Mortgage Rates Hit 7.40%—Your Old Low Rate Still Can’t Move

The average rate on a 30-year fixed mortgage climbed to 7.40% in the latest weekly reading cited on Oct. 20, according to Freddie Mac data reported by Realtor.com News. That was the highest level since 2023 and another blow to buyers already struggling with monthly payments.

For homeowners, the increase reinforces a basic obstacle to moving: A low mortgage rate stays with the old property. A seller who locked in a much cheaper loan several years ago generally must pay it off at closing and obtain new financing for the next home. Congress is again considering whether mortgages should be portable, but sellers should not build current plans around that possibility.

Portable mortgages are a proposal, not a financing option today

A portable mortgage would let an owner transfer an existing loan, including its interest rate and remaining terms, to another property. Rep. Thomas Kean, a New Jersey Republican, introduced the Making Ownership Viable for Everyone Act in June 2026. The bill would direct Fannie Mae and Freddie Mac to purchase portable mortgages.

As of Oct. 20, the bill had no co-sponsors and remained in committee. Congress also discussed portability at a House Financial Services hearing in February, where lawmakers questioned whether the existing mortgage system could accommodate such a significant change.

The central problem is that most U.S. mortgages are packaged into securities based partly on the property securing each loan and assumptions about when that loan will be repaid. A sale normally triggers repayment of a conventional mortgage. Moving the same debt to a different house would disrupt those assumptions and introduce new risks for investors. Lenders could respond by charging higher rates to compensate, reducing some of the affordability benefit portability is supposed to create.

Portability would not eliminate financing gaps, either. An owner moving to a more expensive property would still need enough cash or a second loan to cover the difference. The United Kingdom and Canada permit forms of mortgage portability, but their lending systems rely less on long-term, fixed-rate loans and commonly use shorter rate periods or prepayment penalties.

Today’s rate still determines the size of a seller’s buyer pool

For a seller listing now, the practical number is 7.40%, not the rate on the seller’s existing loan. Most prospective buyers will qualify based on current financing costs. When rates rise, the same household income supports a smaller loan, so some buyers lower their target price, increase their down payment or leave the market temporarily.

That can shrink the buyer pool most sharply around common qualification thresholds. A home priced just above what local buyers can comfortably finance may receive plenty of online attention but few serious showings. If nearby sellers are slow to adjust, listings can accumulate and give buyers more negotiating leverage.

Higher borrowing costs can also lengthen days on market. That does not guarantee a slow sale; condition, location, inventory and local demand still matter. But sellers should be cautious about using a closed sale from a lower-rate period as the only pricing benchmark. Recent pending sales and current competition provide a better view of what financed buyers can support now.

Offer strength may change before the headline price does. A buyer could offer close to asking while requesting closing-cost assistance, a rate buydown, repair credits or a longer financing contingency. Those terms reduce certainty or seller proceeds. Comparing offers means calculating the likely net after concessions, not simply choosing the largest number on the first page.

Assumable loans can help some listings, but eligibility is narrow

An assumable mortgage is different from a portable one. With portability, the seller carries a loan to the next property. With assumption, the buyer takes over the seller’s existing loan on the home being sold, subject to program and lender requirements.

Some FHA, VA and USDA mortgages may be assumable. Realtor.com estimates that roughly 10% of active listings could potentially qualify, yet only about 0.6% of listings mention assumability. Those figures do not mean every apparently eligible loan can be transferred smoothly. Approval requirements, program rules and the gap between the loan balance and purchase price can complicate the transaction.

For example, if the seller’s remaining mortgage is well below the agreed price, the buyer must cover that difference with cash or separate financing. A low assumed rate can still be valuable, but it does not finance equity the seller has built. Sellers should verify the loan type, balance, servicer process and potential timeline before advertising an assumption as a central listing benefit.

VA loan holders need particular care because an assumption can affect entitlement and liability depending on who assumes the loan and how the transfer is handled. This is an area for confirmation from the loan servicer and qualified advisers, not assumptions based on old closing documents.

Price and concessions should be tested against the seller’s next move

Sellers should run two affordability calculations. The first is for the likely buyer: What monthly payment does the asking price create at a current market rate, including taxes, insurance and any association dues? The second is for the seller: What will the next home cost after the existing mortgage is paid off?

That second calculation can reveal whether a sale that looks profitable on paper actually improves the household’s position. Net proceeds should account for the mortgage payoff, transaction expenses, negotiated credits, repairs and moving costs. If the next purchase requires a 7.40% mortgage, the higher payment may outweigh the benefit of accessing equity or buying a different property.

Before cutting the list price, sellers can compare the cost of a reduction with the cost of a targeted concession. A closing-cost credit or temporary rate buydown may help a qualified buyer more than an equal price cut, although the value depends on the loan and lender. Any concession should be measured against the seller’s net and disclosed clearly in the contract.

The key is not to wait for portable mortgages to rescue the market. The MOVE Act could change, stall or never become law, and implementation would require major lending-system adjustments. Sellers deciding in 2026 should plan around financing that exists now, while treating a verified assumable loan as a property-specific advantage rather than a marketwide solution.
