Every buyer in the DMV is asking the same question right now: should I wait for rates to drop?
It’s the wrong question.
The right question is: what happens to the deal I actually want while I’m waiting?
Let’s run the math most people never do.
The Setup
You are looking at a $750,000 condo in DC. Twenty percent down. Thirty-year fixed. Rates this week are 6.30% — a four-week low, but still not the number you were hoping for. The temptation is obvious: hold off, wait for a 5-handle, come back in twelve months.
Here is what that actually looks like.
Scenario A: Buy Now at 6.30%
- Purchase price: $750,000
- Down payment: $150,000
- Loan: $600,000 at 6.30%
- Monthly P&I: $3,714
Not fun. But that is the starting line.
Scenario B: Wait Twelve Months
Rates drop to 5.75%. You feel vindicated. But here is the part nobody models — prices moved 4% while you were on the sidelines. In a market where Northern Virginia absorbed inventory 8% faster in Q1 than a year ago, that is a conservative assumption, not an aggressive one. When rates drop, buyers return. When buyers return, prices firm. That is how this market has always worked.
- Purchase price: $780,000
- Down payment: $156,000 (you need $6,000 more in cash just to start)
- Loan: $624,000 at 5.75%
- Monthly P&I: $3,641
You saved $73 a month. Congratulations.
The Math Nobody Runs
That $73 a month is real. But here is what it cost you:
- $30,000 in appreciation — money the seller made, not you
- $6,000 more in down payment — cash tied up instead of working
- $36,000 in rent over twelve months at $3,000/month — gone, forever
Total cost of waiting: $66,000.
Total lifetime savings from the lower rate, assuming you hold the mortgage for thirty years: $26,000.
You lost $40,000 to save $26,000. And that is assuming rates actually drop half a point — which nobody has reliably forecasted in three years.
The Argument Nobody Makes
Here is the piece that tips the math decisively: you can refinance a rate. You cannot un-buy a property at a lower price.
Buy at 6.30% today. If rates drop to 5.75% in 2027, you refinance and capture the savings — minus a few thousand in closing costs, which the lower rate pays back within a year. You keep the $30,000 of appreciation you earned by owning the asset while you waited. You stop paying rent. You start building equity. You get the tax deduction on mortgage interest.
Date the rate. Marry the house. The cliché exists because the math is real.
The DMV-Specific Reality
This math is particularly sharp in our market right now because the DMV is split. Inside DC, absorption has declined for sixteen straight quarters — softer demand means more room to negotiate and less price risk if you wait. That is a real argument.
But in Northern Virginia, it is not. Arlington and Alexandria are seller markets. Inventory is moving. If you are targeting those neighborhoods and waiting for rates, you are not waiting — you are losing. Every month the Q1 absorption trend continues, the deal you actually want gets more expensive, not less.
The fantasy of lower rates AND lower prices is just that — a fantasy. Historically, those two things do not happen together. They cannot. When money gets cheaper, buyers show up, and prices go up.
What to Do Instead
Stop asking when rates will drop. Start asking these three questions:
- Can I afford the payment at 6.30% today? If yes, you are in the game.
- Is the property I actually want available at today’s prices? If yes, you are in the window.
- Will I regret this purchase if rates drop next year and prices rise 4%? If no, stop waiting.
The window between “waiting for better rates” and “the deal you wanted is gone” is narrower than it looks.
The math backs it up.
