Mortgage rates have been on everyone’s radar lately, and it’s easy to understand why. The average 30-year fixed rate climbed to its highest level in 13 months in early September, hovering near 6.71% according to Freddie Mac, with some daily measures pushing closer to 7%. For buyers watching that number bounce around, it’s tempting to treat the rate as the single deciding factor in whether or not to move forward with a purchase.
The rate alone shouldn’t be treated as a simple yes-or-no answer. Instead, he recommends buyers run the numbers on six specific financial factors before deciding whether to move forward, pause, or adjust their home search. Here’s what to look at.
1. Your Full Monthly Payment — Not Just Principal and Interest
It’s easy to fixate on the principal-and-interest number a lender quotes, but that figure is only part of the picture. A complete monthly payment estimate should include realistic property taxes, homeowners insurance, mortgage insurance, and HOA fees on top of principal and interest. Skipping these can leave buyers with a monthly budget that looks fine on paper but doesn’t reflect what they’ll actually owe.
2. What the Loan Really Costs Over Five Years
A small rate increase can look minor on a monthly basis, but the long-term math tells a different story. On a $350,000, 30-year loan, moving from 6.25% to 7% raises the monthly payment by roughly $174. That may not sound significant until you zoom out: over the first five years, the buyer with the higher rate would pay approximately $13,200 more in interest and build about $2,780 less equity through principal paydown. Most buyers plan to stay in a home well beyond one year, so it’s worth calculating cost over a five-year window rather than just the first monthly bill.
3. How Much Cash Is Left After Closing
A monthly payment might fit comfortably within a budget, but that doesn’t mean the purchase is financially sound if it drains all available savings. Buyers should look closely at how much cash remains after the down payment and closing costs are paid — leaving little to no emergency fund is a bigger red flag than accepting a slightly higher rate while keeping reserves intact.
4. Likely Maintenance Costs in Year One
Big-ticket repairs don’t wait for a convenient time. Before closing, buyers should get a realistic sense of the age and condition of major systems — roof, HVAC, water heater, appliances — so they aren’t blindsided by a large repair bill shortly after moving in.
5. The True Cost of Continuing to Rent
Waiting to buy isn’t free. Continuing to rent comes with its own costs, including ongoing rent payments, the likelihood of annual rent increases, the expense of moving again later, and — perhaps most importantly — the equity a buyer isn’t building in the meantime. Comparing the cost of waiting against the cost of buying now gives a clearer picture than looking at mortgage rates in isolation.
6. Seller Credits and Rate Buydowns
In markets where buyers have some negotiating leverage, sellers may be willing to contribute toward closing costs or a temporary rate buydown. Rather than assuming a lower purchase price automatically produces the best savings, buyers should compare a price reduction against seller-paid credits to see which option actually saves more money over time.
Don’t Forget: Shop Your Lender
One more number worth checking before committing: what different lenders are actually quoting. A 2026 analysis of 3.2 million mortgage originations found that borrowers who didn’t shop around could overpay by an average of $3,363 a year by settling for a less competitive loan. Buyers can’t control where the bond market goes, but they can compare lenders, negotiate credits, and choose a home that leaves room in the budget — decisions that often matter more over five years than trying to time the “perfect” week to lock a rate.
