The Mortgage Rate Lock-In Effect: Why Fewer Lafayette Owners Sell

If you have wondered why there are not more homes for sale in Greater Lafayette, part of the answer is sitting in your neighbors' mortgage paperwork. A lot of owners have a rate they do not want to give up.

Economists call it the mortgage rate lock-in effect. Here is what it is, what the research says, and what it means if you are trying to buy or sell here.

What the lock-in effect is

Most homeowners with a mortgage have a fixed rate. Many bought or refinanced when rates were much lower than they are now. If they sell, they give up that loan and take a new one at today's rate.

That can turn the same size home into a much larger monthly payment. So owners who might otherwise move up, scale down, or relocate across town decide to stay. They are not trapped in a legal sense. They are locked in by the math.

The result is fewer homes coming on the market than you would normally expect. Buyers feel it as thin inventory. Sellers feel it as less competition, but also as a harder time finding their own next home.

What the research found

The Federal Housing Finance Agency studied this directly. In its working paper The Lock-In Effect of Rising Mortgage Rates, FHFA researchers found that for every percentage point that market rates exceed a borrower's original rate, the probability of that home selling decreases by 18.1%. They estimated lock-in prevented 1.33 million home sales nationally between mid-2022 and late 2023.

The same FHFA paper found that the reduced supply pushed home prices up by 5.7%, which outweighed the 3.3% downward pressure from higher rates themselves. In plain English: higher rates made homes harder to afford, but fewer sellers kept prices from falling.

That is national research, not a Lafayette-specific study. It lines up with what I see on the ground here, though, especially in the price ranges where owners bought or refinanced in recent years.

How it shows up in Greater Lafayette

Lock-in does not hit every part of the market the same way.

Move-up homes feel it most. The owner of a starter home who would normally sell and buy something larger faces a higher rate on a bigger loan. Many wait. That keeps starter homes off the market and keeps those same owners out of the move-up market as buyers.

Life events still move people. Job changes, Purdue appointments, growing families, divorce, retirement, and estates keep homes coming to market no matter what rates do. Those listings are a big part of our supply right now.

Owners without a mortgage are not locked in. Owners who have paid off their homes, or who hold very small balances, can move without rate pain. They tend to make up a meaningful share of sellers in some segments.

I covered how supply shapes the whole market in what housing inventory really means.

What it means if you are buying

Fewer listings means less choice and, for well-priced homes, more competition. Be ready to move when the right home appears, with a full pre-approval and a clear sense of your budget. That is the first step in Buy & Move Smart.

It also helps to understand your own payment, not just the price. I walked through that in how interest rates change your buying power.

Ask about assumable loans when a listing has one. Some FHA and VA loans can be taken over by a qualified buyer with lender approval, which can mean inheriting a lower rate. The catch is that you need to cover the gap between the price and the loan balance. I explained how that works in assumable mortgages in Indiana.

What it means if you are thinking about selling

If you are one of the locked-in owners, you are not alone, and staying put can be a perfectly reasonable choice. The question is whether the move you want is worth the higher payment.

A few things belong in that decision.

Your equity. If prices have risen since you bought, you may be bringing a larger down payment to your next home, which shrinks the new loan. I covered how to figure that in home equity explained.

The size of the move. Scaling down can sometimes keep the payment close to where it is now, even at a higher rate. Moving up costs more.

Timing between homes. If you have to buy and sell at once, the order matters. I talked through that in should you sell before you buy your next home.

What waiting costs. Waiting for rates to fall is not free. Your life may need the move now, and nobody can tell you when rates will change or what prices will do in the meantime.

A simple way to run your own numbers

Here is the exercise I do with sellers who feel stuck.

First, get a realistic value for your current home and estimate your net after selling costs. Second, have a lender price out the next home at today's rates with that equity as your down payment. Third, compare the new payment to your current one and to your budget. Fourth, write down what the move would change in your life, beyond the numbers.

Some owners see the payment and decide to stay. Others realize the difference is smaller than they feared, or that the move is worth it. Either way, the decision is based on your numbers instead of a headline.

Why lock-in can make the market feel stuck in both directions

Lock-in creates a strange loop. The owner who would sell a starter home stays put, so the first-time buyer has fewer homes to choose from. The same owner is not shopping for a larger home, so the move-up seller has one fewer buyer. Each household that stays affects two parts of the market at once.

That is why a market can feel slow and competitive at the same time. Fewer homes trade hands overall, yet the well-priced homes that do come up can still draw several interested buyers. People see the low sales volume in a headline and assume prices must be soft. On the ground, the two things often sit side by side.

It also explains why I pay close attention to the reason each seller is moving. When most listings come from life events rather than choice, sellers often have firm timelines, and buyers who understand that can write cleaner offers that fit the seller's needs instead of just pushing on price.

Will it last

I cannot predict rates, and I would be wary of anyone who says they can. What I can tell you is that lock-in loosens over time. Life keeps moving people, owners gradually build equity, and if rates drift closer to what people already hold, more owners will list.

When that happens, inventory tends to rise, and the balance between buyers and sellers shifts. Watching new listings in your price range is one of the earliest ways to see it coming.

What the headlines cannot see

The market is the market. National research tells you why supply is tight in general. It does not tell you which owners on your street just refinanced, which ones have a job change coming, or which homes are about to come up before they ever appear online.

You can find listings anywhere. What you cannot Google is what is coming to market next week and who is finally ready to move. That local knowledge is what actually protects you in a market where supply is thin.

If you are weighing whether to give up your rate, or how to buy when choices are limited, grab a time on my calendar and we will run the real numbers together. You can also start with a home value estimate. No pressure either way.
