Mortgage rates dominate the conversation when homeowners think about moving. But for someone who already owns a home, the interest rate on the next mortgage is only one side of the equation. The other side is the equity that may have accumulated through years of principal payments and home-price growth.
The national equity number is substantial
Cotality data highlighted in Keeping Current Matters' September 2026 report shows the average U.S. borrower had about $310,500 in home equity in the first quarter of 2026. Cotality estimated total mortgage-holder equity at roughly $17.9 trillion across 56.7 million U.S. properties. KCM's state-by-state map placed Colorado at roughly $349,000 in average homeowner equity.
Those are averages, not estimates of what any particular homeowner owns. A recently purchased home, a heavily financed property and a home owned for 20 years can produce completely different numbers. Still, the broader point is important: many homeowners have built a financial cushion that can materially change what their next move looks like.
A low mortgage rate can create tunnel vision
It is understandable for an owner with a 2%, 3% or 4% mortgage to look at today's rates and say, 'I'm never moving.' The problem is that comparing old rate versus new rate leaves out the balance sheet. If selling creates a large amount of usable proceeds, the next purchase may require a much smaller loan than the sticker price suggests.
The useful questions are not only 'What rate would I get?' and 'What would the next house cost?' They also include: What is the current home's realistic market value? What is left on the mortgage? What selling costs should be accounted for? How much cash should remain in reserve? And how much of the remaining proceeds would actually be applied to the next purchase?
Equity is not the same thing as spendable profit
This distinction matters. Home equity is generally the difference between a property's market value and debt secured by the property. It is not automatically the amount an owner will walk away with at closing. Mortgage payoff, transaction expenses, possible repairs or concessions, taxes and the owner's broader financial plan can all affect net proceeds.
That is why a homeowner should estimate the full sale-and-purchase picture before deciding a move is either impossible or easy. A strong equity position can create options, but it should be modeled realistically.
Three ways equity can affect a move
A larger down payment can reduce the size of the next mortgage and soften the effect of a higher interest rate.
A downsizer may be able to purchase with a very small loan or, in some cases, without financing, depending on sale proceeds and the next home's price.
A move-up buyer can compare the cost of staying versus moving using actual estimated proceeds rather than assuming the existing low rate makes relocation impossible.
What about HELOCs and home equity loans?
KCM also points to increased use of home equity through HELOCs and home equity loans. Cotality reported a 10% quarter-over-quarter increase in homeowners tapping equity in the first quarter of 2026. Those tools can be useful in the right circumstances, but borrowing against a home creates debt secured by the property. The rate, payment, tax treatment and risk depend on the loan and the household's finances, so this is an area to evaluate with the appropriate lender, tax professional, attorney or financial advisor rather than treating equity as free cash.
What this means for Colorado homeowners
For a homeowner considering a sale, the practical first step is not to guess from an online estimate. Start with a property-specific value range, subtract the actual loan balance and expected selling costs, then model the next purchase using a realistic amount of available proceeds. The Denver Metro market page provides current local context, while the seller planning section explains how pricing, preparation and estimated proceeds fit into a broader selling decision.
If you are also buying, today's negotiating environment matters too. Fall 2026 is giving prepared buyers more leverage, and the amount of equity brought from a current home can further change the financing picture.
The bottom line
A low existing mortgage rate is valuable, but it is not the only financial asset attached to a home. Before deciding that moving no longer makes sense, understand what the property may be worth, what you may actually net and how that equity could change the next payment. Sometimes the conclusion will still be to stay put. Sometimes the numbers reveal more flexibility than expected.
