A new study from AD Mortgage just put a number on the “wait for better rates” strategy — and it’s not flattering for the waiters. Across 61% of the scenarios they modeled, buyers who purchased now came out ahead financially compared to those who held off. That’s not a gut feeling or a realtor pep talk. It’s a simulation run across hundreds of combinations of price, rate, and timeline variables.
Here in the Phoenix metro, that finding should land with some weight. I talk to buyers every week who are convinced the smart play is to sit tight, let rates drop, and jump in when things “calm down.” The data suggests that strategy backfires more often than it works.
Why Waiting Feels Logical But Often Isn’t
The thinking goes like this: if rates drop from 6.8% to 5.9%, monthly payments shrink, so waiting is worth it. Clean logic. The problem is that it ignores two things that don’t pause while you wait — home prices and opportunity cost.
In Phoenix, we’ve watched median home prices in suburban markets like Gilbert and Chandler absorb rate increases without much give. As of recent market data, the Phoenix metro median sits around $430,000 to $450,000 depending on the month. A rate drop that finally convinces 50,000 sidelined buyers to move will not arrive in a vacuum. It arrives alongside renewed competition, bidding wars, and price pressure. The rate goes down; the purchase price goes up.
The AD Mortgage study models exactly this dynamic. In most scenarios, the price appreciation that accumulates during the waiting period — combined with the months of rent paid instead of equity built — erases the benefit of a marginally lower rate.
The Numbers That Actually Move the Needle
Let’s make this concrete for an Arizona buyer. Say you’re looking at a $420,000 home in Mesa today with a 6.7% rate on a 30-year fixed. Your principal and interest comes to roughly $2,720 per month. Now say you wait 18 months for rates to hit 5.9% — a scenario that’s possible but not guaranteed. If that same home appreciates just 4% annually (conservative for this market over the past decade), it’s now priced at around $453,000. Your payment at 5.9%? About $2,690.
You saved $30 a month. And you paid rent for 18 months instead of building equity.
That’s the trap. The monthly payment looks similar, the price is higher, and you’ve handed your landlord somewhere between $25,000 and $45,000 in rent with nothing to show for it on a balance sheet.
The AD Mortgage study found that in scenarios where appreciation runs even modestly positive, buying sooner wins — and it wins by a wider margin as the holding period lengthens. Only in scenarios where prices actually decline meaningfully (10% or more) does waiting pay off clearly.
What This Means in the Phoenix Market Specifically
Phoenix is not a price-decline market right now. Inventory is tighter than it looks on paper. We have more active listings than we did in 2022 and 2023, but a meaningful chunk of that inventory is overpriced and sitting — not evidence of softness, just sellers anchored to peak-era comps.
The genuinely well-priced properties in Tempe, Peoria, and the East Valley are still moving within two to three weeks. I’ve seen multiple-offer situations on anything under $400,000 in good school districts. That’s not a market that’s going to hand you a discount for being patient.
Affordability is actually improving in some respects as wage growth continues to outpace price increases in parts of the market — but that window doesn’t stay open forever, and it’s not the same as prices going backwards.
The Scenarios Where Waiting Does Make Sense
To be fair to the study’s nuance: 39% of the scenarios still favored waiting. That’s not nothing. Waiting tends to win when:
- You genuinely can’t afford the monthly payment right now without stretching your DTI past comfortable limits
- You’re planning to stay in the home fewer than 3–4 years (short holding periods compress the equity-building advantage)
- You expect a significant job change, move, or life event in the next 12–18 months
- You’re in a local market where supply is genuinely growing faster than demand
Phoenix checks that last box in specific pockets — some of the outer suburbs like parts of Buckeye and Maricopa have more builder inventory coming online, which keeps a ceiling on appreciation. But core metro? Not so much.
It’s also worth being honest about financing strategy. Some buyers in today’s market are exploring adjustable-rate mortgages as a way to buy now at a lower initial rate and refinance when the market shifts. That’s a legitimate play if you understand the risk and have a clear timeline.
Don’t Let Perfect Timing Be the Enemy of a Good Deal
The buyers I’ve seen win in this market aren’t the ones who nailed the timing. They’re the ones who found a solid property, negotiated hard on price or seller concessions, and got in before appreciation ran away from them. A rate you can refinance later. A price you paid too much for is baked in.
The AD Mortgage findings confirm what I’ve seen on the ground here for years — the “wait for the perfect rate” strategy is mostly a story people tell themselves to feel better about inaction. Sixty-one percent of the time, the math disagrees.
If you’re sitting on a preapproval, have a stable job, and plan to stay in a Phoenix-area home for five or more years, the study’s conclusion is simple: the cost of waiting is probably higher than you think. Get in, build equity, and refinance when the opportunity comes.
