The Cost of Waiting: Why Selling Now With Your Low Rate Beats Waiting for Rates to Drop

I hear this all the time from sellers: "I'll wait until rates come down, then sell."

The logic seems reasonable. If rates drop, more buyers can afford homes, demand goes up, prices go up, and you sell for more. Right?

Maybe. But there's a massive flaw in this plan that most sellers aren't considering. And it has everything to do with your assumable mortgage.

The Flaw in the "Wait for Lower Rates" Strategy

Your assumable rate is valuable because of the gap between it and current market rates. With rates at 6.5% to 7%, a buyer assuming your 2.75% loan saves over $1,000/month compared to getting a new mortgage. That savings is what makes buyers pay a premium for your home.

Now imagine rates drop to 5%. That gap shrinks from 4 percentage points to 2.25 points. On a $400,000 loan, the monthly savings goes from about $1,027/month down to roughly $480/month.

Still good. But the premium a buyer is willing to pay for your assumable rate drops significantly.

At 4.5%? The gap is 1.75 points. Monthly savings: about $370.

At 4%? The gap is 1.25 points. Monthly savings: about $260.

See the pattern? Every quarter-point drop in market rates reduces the value of your assumable mortgage to buyers. The very thing you're waiting for (lower rates) is the thing that makes your biggest selling advantage less powerful.

Run the Numbers on Waiting

Let me make this concrete. Say your home is worth $475,000 today with a $400,000 loan balance at 2.75%.

Scenario 1: You sell now (rates at 6.8%)

• Monthly savings for buyer: $1,027
• Lifetime interest savings for buyer: ~$370,000
• Premium buyers are willing to pay: significant, often full asking or above
• Your equity: approximately $75,000

Scenario 2: You sell in 18 months (rates drop to 5.5%)

• Monthly savings for buyer: $640
• Lifetime interest savings for buyer: ~$230,000
• Premium buyers are willing to pay: moderate
• Your equity: maybe $80,000 to $85,000 (if prices appreciate modestly)

So by waiting, you might gain $5,000 to $10,000 in equity from appreciation. But you lose a massive chunk of the assumable premium. The rate-driven bidding wars, the above-asking offers, the motivation that makes buyers stretch? All of that weakens as the gap narrows.

And that's assuming rates actually drop. Which brings me to the next point.

Nobody Knows When (or If) Rates Will Drop to 4%

Rates were below 3% from 2020 to early 2022. That was an anomaly. Before that, rates hadn't been that low since... well, ever. The long-term average for a 30-year fixed mortgage is between 7% and 8% going back to the 1970s.

Rates at 6.5% aren't high by historical standards. They feel high because we got used to something that was genuinely unusual.

The Fed doesn't control mortgage rates directly. Inflation, bond markets, global economics, geopolitics. All of these influence where rates go. Plenty of economists predicted rates would be back in the 4s by 2025. They're not.

Waiting for rates to drop to a specific number is a gamble. And while you're gambling, the value of your assumable rate is at its peak right now.

The Opportunity Cost of Sitting

Beyond the assumable math, there's the regular opportunity cost of not selling when your life situation calls for it.

Career moves you're delaying. If a better job in another city is on the table, every month you wait is a month of lost income or career growth.

Space you need. If your family outgrew the house, you're paying the cost of being cramped in ways that don't show up on a spreadsheet. Stress, storage units, the kid sleeping in a converted office.

Investment returns you're missing. If you'd sell now and deploy your $75,000 in equity into a new home, investment, or down payment, that money starts working for you today. Every month it sits locked in your current home's walls, it's doing nothing except appreciating at whatever rate the local market gives you (which in most Colorado markets is 2-4% annually right now).

Maintenance and carrying costs. Every month you own a home, you're paying the mortgage, insurance, property taxes, HOA (if applicable), and maintenance. If you're staying purely because of the rate and not because you love living there, those carrying costs add up.

"But My Rate Is So Good, I Don't Want to Lose It"

I covered this in depth in my post about whether to sell with a low-rate mortgage, but the short version: you're not losing your rate. You're selling it.

Your buyer takes over the rate. You take your equity in cash. Then you use that equity to make your next move (bigger down payment, investment property, whatever makes sense for you).

And yes, your next mortgage will probably be at a higher rate. But a higher rate on a smaller loan (because you're bringing significant equity to the table) can result in a very manageable payment.

The Military Seller Angle

For military families, this is especially relevant. PCS orders don't care about interest rate forecasts. When the Army says move, you move.

If you're PCSing and you have an assumable loan, you're in the strongest possible selling position right now. The rate gap is wide, assumption demand is high, and military buyers at your next duty station's base are actively looking for assumable deals.

Waiting out your orders hoping rates drop before your report date is a losing strategy. Sell now, capture the assumable premium, take your equity, and move on.

What If Rates Go Up Instead?

Here's a scenario nobody talks about. What if rates don't drop? What if they hold at 6.5% or tick up to 7%+?

In that case, your assumable rate becomes even more valuable over time. But you also face a market where buyer pools are shrinking, affordability is getting worse, and selling any home gets harder.

The best time to sell an assumable property is when rates are high enough to make the spread valuable but not so high that the overall market freezes up. That's roughly where we are right now.

Making Your Decision

I'm not going to tell you what to do. Your situation is yours. But I want to make sure you're seeing the full picture.

If you're holding onto your home purely because of the rate, and your life would be better if you sold, you're paying a cost for that decision every day. And the assumable premium that makes your home especially valuable to buyers? It's at its peak right now.

If rates drop, that premium shrinks. If rates stay high, you still have the advantage, but the market itself might be tougher. The sweet spot is now.
