The Homeowner’s Guide to Navigating High Rates, Hidden Equity, and Life Changes
By Kofi Nartey, CEO of GLOBL
The Dilemma
If you hold a mortgage at a very low fixed rate (say 2.75% to 4%) and you’re now thinking of moving or upgrading at a time when new 30-year fixed mortgage rates may be upwards of 6% or higher, you’re in a rare but growing situation. On one hand you may have legitimate reasons to move (bigger family, new job, lifestyle change, better neighborhood). On the other hand you’re reluctant to give up what may be one of the most financially favourable loans in your lifetime.
As one headline puts it: homeowners are feeling “locked in” by their ultra-low rates. realtor.com+2finance.yahoo.com+2 The shift in borrowing cost creates a financial barrier to moving. U.S. Bank+2Rocket Mortgage+2
Given that dynamic, the purpose of this article is to arm you (the homeowner) with a full toolkit of strategies and decision-frameworks — so that you can make a move if you need to, without feeling like you’re leaving money on the table. We’ll walk you through: what you’re giving up by leaving the low rate; what you’re getting into; several creative and conventional strategies; how to model the numbers; and how to decide.
What you’re giving up (and what you’re entering)
The “benefit” of your low rate
When you locked in, say, 3.25% on a 30-year fixed loan during a low-rate period, each successive payment is cheaper than what someone else might pay today on the same loan amount at say 6.25%. That difference manifests in monthly payment, total interest cost, and in effect gives you “extra” cash flow or equity build-up relative to a new borrower at higher rate.
As one commentator notes: “It’s ‘shadow’ because the only way to monetize it is to let time elapse until the mortgage goes away.” moontowermeta.com In effect your low-rate loan acts as a “hidden asset” or at least a significant cost advantage.
The “cost” of moving
If you move and buy a new home, you’ll presumably take out a new loan at the current market rate. If rates are say 6%+, then your monthly payment and interest cost will be significantly higher — all else equal (loan size, term). Often you may also be buying a more expensive home (so you’re combining higher loan size + higher rate). That means your payment could rise materially unless you take steps to mitigate.
As the article on “The Cost/Benefit of Giving Up a Low Mortgage Rate” points out:
“Let’s assume you have a $500k house with a 20% down payment. At 2.75% that’s … $1,630 a month. Now … at 5.75% … more than $2,330.” A Wealth of Common Sense
Also, the “lock-in effect” is not just theoretical: survey data shows that many homeowners are postponing their move because they are unwilling to take on a much higher rate. realtor.com
Quantifying the gap
Let’s work a simple example. Suppose you currently have:
- Loan amount: $300,000
- Interest rate: 3.25% fixed
- Term remaining: 25 years (for simplicity)
- Monthly payment (principal + interest): Roughly $1,460.
(Using standard amortization tables)
Now you plan to buy a new home requiring you to borrow $400,000, and new rate is 6.25% for 30 years. Monthly payment on $400k @6.25% ~ $2,463 (approx). So you’re looking at ~$1,000+ more per month. Over 12 months that’s $12,000 extra annual cash outflow. Over 10 years, ignoring prepayment, you’re looking at ~$120,000 higher paid (plus lost opportunity of paying down principal faster) simply because of rate + size.
Thus: you need to justify that increased cost by benefits of the move (better home, better location, lifestyle, future value) or mitigate the cost via strategy.
Strategic Options
Below is a menu of strategies — some conventional, some creative. You may combine them. What matters is modelling your numbers, involving your advisors, and aligning with your broader life/financial goals.
Strategy 1: Port or assume the existing loan (if possible)
Mortgage porting
In some jurisdictions (especially outside U.S.) lenders offer porting of a mortgage: you move the loan to a new property, keeping the same interest rate, term (or adjusted term) and pay any difference for the larger loan at the current rate. For example, you keep your $300k 3.25% loan and borrow an extra $100k at new rate. In the U.S., this is less common. But one article notes lenders may allow “transfer of mortgage” under certain conditions. Hellmuth & Johnson+1
Example:
- Old loan: $300k @ 3.25% for 25 years → $1,460/month.
- New home: you need $400k total. You “port” $300k at 3.25% and borrow extra $100k at say 6.25% → ~$709/month for that part. Combined payment ~$2,169/month (versus ~$2,463 if full $400k @6.25%).
- Advantage: you keep most of the low rate.
- Disadvantage: you still take on a new higher-rate loan portion; lender must offer porting, new home value/qualification etc. Many U.S. institutional loans don’t permit. Implementation complexity.
- Consult your lender: ask about “rate and term transfer”, “assumable/portable loan”.
Assumable mortgage
Certain government-backed loans (especially Federal Housing Administration (FHA), Department of Veterans Affairs (VA), United States Department of Agriculture (USDA)) may be assumable. That means a buyer can take over your existing loan and its rate, subject to lender approval. Hellmuth & Johnson+1 This is relevant not so much for staying in your home, but if you’re selling and the buyer can assume your low rate — that becomes a marketing tool. But for you moving, it may not help unless your buyer assumes your loan and you simply buy new. This requires that your loan be assumable and buyer qualifies.
Cooling considerations
- Porting/assumption are rare in standard U.S. conventional mortgages. Due‐on‐sale clauses often prohibit transfer without lender’s consent. Hellmuth & Johnson+1
- Even if you port, you may be constrained to similar loan size or take second lien for difference.
- Fees and underwriting may apply.
- Example: if you have this option, it can dramatically reduce cost of moving. But don’t assume it exists: check loan docs and lender policy.
Strategy 2: Sell and use equity + larger down payment to offset higher rate
If you move and accept taking a new rate at 6%+, what you can do is use your existing home’s strong equity (likely given low rate + price appreciation) to reduce the size of your new mortgage, thereby mitigating the pain of higher rate.
Example:
- Suppose you own home with value $600,000, outstanding loan $300,000 @3.25%. Equity $300k.
- You sell, move to a home priced $800,000. Instead of borrowing $640k (if 20% down), maybe you put 40% down (e.g., $320k), so you borrow ~$480k. At 6.25% for 30 years → monthly payment ~$2,954. Compare to what you’d owe if you borrowed $640k → ~$ $3,935/month. Big difference.
- Or you buy a slightly smaller home／price. Use large down payment to keep loan size lower.
- In short: use the equity to “buy down” loan size. Payment shock is more manageable.
- Also remember — higher down payment may help interest rate slightly.
Pros: Straightforward. You lock in profits.
Cons: You still pay the higher rate. Might require staying longer to amortize cost.
Strategy 3: Sell your home, buy the new one but plan to refinance when rates drop (bridge the gap)
You accept you will pay a higher rate for now, but you’re moving because reasons outweigh the cost. You plan to refinance once/if rates drop. In the meantime, you might take some steps to cushion the pain.
Example:
- New home price: $450,000. Loan $360,000 @6.25% → payment ~$2,775/month.
- Later you sell old home, apply $100,000 equity. Now your loan is $260,000 at same rate until you refinance. Payment ~$2,012/month (still at 6.25%, amortizing 30 years).
- When rates drop (say to 4.5%), you refinance the $260k and drop payment further.
- You could also buy down points up front for the new loan (pay extra up front to reduce rate slightly).
- Work with your mortgage broker to include a “no-prepayment penalty” loan so you can refinance with ease later.
Pros: Enables the move now. Keeps an eye to the future when rates improve.
Cons: You pay the higher rate until you can refinance — if rates don’t drop, you might be “stuck” longer than expected. You must be disciplined with equity and payment structure.
Strategy 4: Rent out your old home, buy the new one (become a landlord)
Instead of immediately selling your current home with the low rate, you hold it as a rental property (or second home), and purchase the new home. This allows you to keep the low rate asset while still making your life move.
Example:
- Old home: mortgage payment $1,500/month. You estimate rent of $2,500/month. Net positive ~$1,000 before expenses.
- You buy the new home: perhaps borrow at 6.25% for $400k → payment ~$2,463/month (as earlier example).
- The rental income helps qualify you for the new loan (lenders count part of rental income) and helps cover your new payment.
- Over time, the rental may also appreciate and build additional equity.
- When the new home value rises or you’ve held for some years, you could sell the original or keep it longer term as investment.
Pros: Keeps your low rate loan anchored in the first home; uses equity/income from that to help with new home.
Cons: Being a landlord has responsibilities (vacancies, repairs, property management). You now own two homes temporarily (cost, taxes, insurance). Market risk for rentals. Must consider tax and insurance implications. Also your new rate is still high unless you mitigate it.
Strategy 5: Creative / Alternate financing approaches
Beyond the standard path, you may consider more creative structures. These require careful legal, tax, insurance review.
Shared‐equity / partner financing
For example you partner with an investor or institutional firm that provides part of the down payment in exchange for sharing appreciation. This can reduce how much you borrow (thus reducing rate burden). Work like this: you finance $300k, investor funds $100k; you agree to split 25% of future appreciation. This can help you keep monthly payment lower, though you give up part of upside.
Rent-to-own / lease with option
You could lease your new home (or the one you are buying) for a period, with rent credits toward down payment. While you continue holding your low-rate home or delaying sale. This grants flexibility while you prepare for full purchase. (Less common, needs good contract terms and legal advice.)
Seller financing / “subject-to” arrangements
You might negotiate with a seller to take over their existing loan (at their lower rate) or structure part of the purchase as seller-financed at favourable terms. This is more complex, and you must assess due-on-sale clauses, tax outcomes, title risk, etc. Hellmuth & Johnson+1
Buy-down or discount points
Even with a higher rate, you can pay upfront discount points to reduce your rate. For example pay 2 points (2% of loan amount) to get the rate down from 6.25% to maybe 5.75%. If you plan to stay long term, this may make sense. See article on buydowns. HomeLight
Decision Framework: How to Choose Which Strategy
As advisors from varied disciplines, we suggest the following step-by-step framework.
Step A: Clarify your trigger and time-horizon
- Why do you want to move? (Lifestyle, family, job, school, etc.)
- How urgently? Can you wait 6-12 months or must it be now?
- How long do you plan to stay in the next home? 5 years? 10+ years? The longer the horizon, the more moving makes sense.
- How much equity do you have in the current home? (Especially useful if you plan to use that equity.)
Step B: Model your current home’s “value of the rate”
- What is your current remaining loan balance, term left, rate?
- What is your current monthly payment (P&I)?
- Estimate new home cost, new loan amount, new rate (e.g. 6%+). Compute new monthly payment.
- Compute difference in monthly payments, difference in total interest cost (over say 5 years, 10 years).
- Ask: “What would it cost me to give up my low-rate loan?” There are opportunity costs. (Some articles show that homeowners often under-appreciate the “lost benefit” of the low rate.) A Wealth of Common Sense+1
- Consider the “lock-in effect” – you may be stuck unless benefit of move outweighs cost. realtor.com+1
Step C: Model each strategy’s numbers
Pick the strategies above that are feasible for you (porting, rental, bigger down payment, etc.) For each one:
- Estimate payment, loan size, rate, term.
- Estimate additional costs (renting old home costs, property management, taxes).
- Estimate tax implications (capital gains, rental income, depreciation, 1031 if applicable).
- Estimate timeline until you might refinance (if that is part of strategy).
- Estimate risk: what if rates don’t drop? What if home prices decline? What if rental vacancy occurs?
Step D: Evaluate qualitative factors
- Does the new home/location significantly improve lifestyle, commute, family quality, future value?
- Are you comfortable managing a rental property (if you go that route)?
- Are you comfortable with somewhat higher payment risk for now?
- Insurance & estate planning: does your situation change (you may want additional life / disability insurance if you take on a bigger loan or rental exposure).
- Tax strategy: If you rent the old home, you’ll convert primary residence to investment — this has impact on capital gains exclusion ($250k/$500k if you’ve met the 2-of-5 years rule) and depreciation recapture.
- Liquidity: Do you have reserves? Moving and owning two homes can throw off cash flow if not managed.
Step E: Create a “worst-case/best-case” scenario and decide your threshold
- Worst-case: Rate stays high for many years, you carry bigger payment longer than planned, home value drops.
- Best-case: You move, rates drop soon, you refinance, payment comes down, home appreciates.
- Decide: “I am willing to pay up to $___ per month more or $___ in total cost over 10 years to make this move because of the lifestyle benefit I expect.”
- If the additional payment or cost is less than your threshold/value, move; if more, hold off or adopt a strategy to mitigate.
Real-World Numeric Case Study
Let’s build a worked example with assumptions:
Current home
- Outstanding loan: $350,000
- Rate: 3.25% fixed
- Term remaining: 30 years (for simplicity)
- Monthly P&I: ~$1,523
New home scenario
- Home price: $550,000
- New down payment: 20% → $110,000
- New loan: $440,000
- New rate: 6.50% (30-yr fixed)
- Monthly P&I: ~$2,783
Payment difference: ~$2,783 − $1,523 = $1,260/month extra.
Strategy A – Straight move: Sell current home, buy new, new loan at 6.5%. Payment jumps by $1,260/month.
Strategy B – Use higher down payment: Suppose you put 40% down ($220,000). New loan $330,000 @6.5%. Monthly P&I ~ ~$2,088 → difference ~$565/month. Much more manageable. You have sacrificed some liquidity (used more down payment) but payment rises modestly.
Strategy C – Rent current home: You don’t sell. You rent your current home for $2,800/month (estimated rental market). Net after expenses (tax, insurance, property management, vacancy) maybe $1,800/month net. You buy the new home with, say, 20% down ($110k) and borrow $440k @6.5% as before → $2,783/month. But your rental income helps you qualify and offset cost. You’re paying ~$983/month net on new home after rental income ($2,783 − $1,800) though you still carry the old loan (which is $1,523 payment) and other costs. You’ll need to run the full cash-flow.
Strategy D – Plan to refinance: Use Strategy B (smaller loan) and assume you will refinance in, say, 3 years if rates drop to 4.5%. In 3 years payments at 6.5% will have paid down principal to maybe ~$310,000 (assuming some schedule). If you refinance to 4.5% for 27 years (remaining), your payment would drop to maybe ~$1,584/month — essentially back to near your current level. So your “extra cost” is essentially carrying ~$565/month for 3 years letting you move now, then payment drops. That might be an acceptable “premium” for the move benefit.
Risks & Pitfalls (and Insurance / Financial Planning Considerations)
- Rates may not drop: If you’re counting on refinancing in 3 years and rates stay high, you could be stuck with the higher cost.
- Home value risk: Moving to a more expensive home means you’re more exposed if values decline (or linger).
- Rental risk: If you hold the old home as a rental, you may face vacancy, market downturn, higher maintenance/management costs.
- Insurance & liability: Owning two properties, rental property exposure, may require additional insurance, landlord liability protection, and you need to check your life insurance coverage (if you increase debt, you might want larger life/ disability coverage).
- Tax consequences: Converting your primary residence to rental means you lose the primary‐residence capital-gains exclusion unless you meet requirements. Depreciation recapture could hit. Consult your tax advisor. realtor.com
- Liquidity & cash flow: Bigger down payment or higher payments reduce cash for emergencies or other investments — a financial planner will point this out.
- Opportunity cost of rate advantage: Some experts argue you may “incinerate” the benefit of your low rate if you sell too soon without fully weighing the cost of replacement. moontowermeta.com+1
- Lock-in effect meaning less mobility: Some homeowners are simply staying put because cost to move is too large. But if your reason to move is strong (job, family), staying put may cost you in other ways (commute, quality of life).
Recommendation: A Balanced Approach for Moving Now
Given all of the above, here’s how we advise our clients to structure a move when they have a low rate and want to change homes.
- First, don’t let the rate alone dictate inaction. If your life situation strongly points toward moving (needs bigger home, job relocation, family demands), then staying simply to retain the low rate may cost you more in intangible and future value.
- Second, treat your current low-rate loan as a valuable asset. Quantify how much extra you’d pay by giving it up and treat that number as a “cost of moving”. Let’s say for you it’s $800/month extra; then ask: is the benefit of the move worth $800/month for the expected time horizon (say 10 years)?
- Third, pick or blend strategies to reduce that cost:
- Use more down payment to reduce loan size.
- Consider keeping your current home as rental (if practical).
- If possible explore loan porting/assumption (rare but worth asking).
- Design your new loan with refinancing flexibility (no penalty, points buy-down).
- Fourth, make sure you have a “contingency exit” plan: e.g., after 3 years you’ll reassess and refinance if rates drop; if not you’ll hold for the longer term. Build scenario models: if rates stay at 6.5% or go to 8%, what happens? How long until payment burden becomes unacceptable?
- Fifth, coordinate with professionals:
- Mortgage broker/lender: understand all options, check loan type, fees, porting.
- Real-estate agent: market your current home well, understand timing, price, buyer readiness in a high-rate environment. Note many sellers are currently holding off because they feel locked in. realtor.com
- Financial planner: run cash-flow, net worth, investment alternatives. Does moving make sense relative to staying and investing elsewhere?
- Insurance/estate planner: update your life/disability insurance if new debt; review landlord insurance if rental; review estate impact if you own two homes.
- Sixth, execute with a timeline:
- Pre-list your current home, get market readiness.
- Get pre-approved for new loan with realistic rate scenarios.
- Negotiate with both sale and purchase to align timing (to avoid double mortgage burden).
- If keeping old home as rental, set up property management, reserves, tax strategy in advance.
Key Takeaways for Homeowners
- Holding a 2.75%-4% mortgage in a 6%+ rate era is a rare cost advantage — don’t trivialize it.
- But life changes (bigger home, better neighborhood, relocation) may outweigh purely financial logic of staying.
- The extra cost of moving (higher rate + possible larger loan) can be mitigated significantly via: higher down payment, keeping current home as rental, loan porting/assumption (where possible), planning to refinance.
- Always run the numbers: payment increase, cost differential, timeline, equity, risk scenarios.
- Make sure to think beyond the monthly payment — think total cost, lifestyle benefit, flexibility, future refinancing potential.
- Work with a team (mortgage, real-estate, financial, insurance) to ensure all angles are covered (cash flow, tax, risk).
- Your decision doesn’t have to be “stay exactly as you are forever” or “move and accept massive payment jump”. There’s a spectrum of strategies in between.
- If the move is strong-justified (job, life, family), then with smart structuring you don’t have to feel like you’re “giving up” everything by leaving your low rate — you can aim to optimize.
Conclusion
If you are married to your low interest rate on your home loan but want to divorce the house and move on to something better, you’re not stuck. You’re in a unique and very strategic position. Yes, the rate differential is real and meaningful — but with planning, creativity, and the right guidance you can structure a move that makes sense both for your finances and your life.
Think of your low rate as a strong asset, and your decision to move as a major life investment. The task is to bridge between them. Use the strategies above, model your unique numbers, consult your team of advisors, and pick the path that balances cost, benefit, risk and timing. If you do, you’ll move on your own terms — not from necessity, but by design.
