Stop Looking at Zillow. Your Mortgage Rate Just Went Up 0.4% in a Week.
Stop looking at Zillow. I mean it. Put down your phone. Close the app. Because that house you saved last week — the one with the granite countertops and the finished basement and the "price recently reduced" tag — just got $180 more expensive per month. And it's not because the seller raised the price. It's because your mortgage rate did.
I live in Roslindale, Boston. I've been tracking the Greater Boston housing market since 2019. And I've never seen volatility like this. Mortgage rates went from 6.25% to 6.41% in a single week last month. That's a 0.16% jump. On a $500,000 mortgage, that's $52 more per month. In one week. Because bond yields climbed. Because oil prices rose. Because someone somewhere did something that made investors nervous.
And here's the part that makes me want to throw my laptop: the market is still defying logic. Even with rates at 6.4%, existing home sales in Greater Boston have posted consecutive positive weeks. Pent-up demand is outweighing sticker shock. Buyers are so tired of renting that they're absorbing rates that would have killed the market five years ago. The median sale price in Boston is hovering around $650,000. With 6.4% rates and 20% down, that's a monthly payment of $3,280. Before taxes and insurance. Before HOA fees. Before the inevitable repairs that come with a 100-year-old Boston colonial.
I had a client — let's call her Priya — who was pre-approved at 6.25% in April. She found a condo in Somerville for $520,000. By the time she made an offer, rates were 6.45%. Her monthly payment went from $2,560 to $2,620. She panicked. She asked the seller for a $10,000 price reduction to offset the rate increase. The seller said no. Three other buyers were interested. Priya walked away.
Two weeks later, the condo sold for $515,000. The buyer who got it had a 6.5% rate. Priya called me, furious. "I should have just paid the extra $60 a month." She was right. She should have. But she couldn't see past the number. She couldn't see that $60 a month — $720 a year — was nothing compared to the cost of staying in her rental, which was going up $200 a month at renewal.
The math of waiting is brutal. If rates go down to 5.5% next year — and that's a big if — Priya would save $280 a month. But if home prices rise 3% in that same year, the $520,000 condo becomes $535,600. Her down payment goes up. Her closing costs go up. And she pays another $2,400 in rent while she waits. The net savings? Maybe $1,000. Over a year. For the stress of timing the market.
Here's what I tell buyers now. Stop trying to time the rate. You can't. The bond market is driven by geopolitics, Federal Reserve policy, inflation data, and random tweets from people you've never heard of. If professional economists can't predict rates, you certainly can't. Focus on what you can control. Your down payment. Your credit score. Your debt-to-income ratio. Your savings rate.
The "3% rule" is real in Boston right now. Sellers are cutting prices by at least 3% to spark faster sales, especially in the $350K-$650K mid-market. That's not a crash. That's a negotiation. If you're a buyer, use it. Make an offer 3-5% below asking. The worst they can say is no. And in this market, with inventory slowly rising, some will say yes.
But also be realistic. The 3% mortgage is gone. It might come back. It might not. If you're waiting for 3% before you buy, you might be renting forever. And renting forever is its own kind of financial trap. No equity. No tax deductions. No stability. Just a monthly payment that goes up every year.
I'm not saying rush into a bad deal. I'm saying run the numbers. Calculate the total cost of buying at 6.4% vs. renting for another year. Factor in equity buildup. Factor in tax benefits. Factor in the emotional cost of instability. Then decide. But decide based on math, not on Zillow alerts.
Priya bought a different condo last month. $495,000. Rate of 6.5%. Her payment is $2,510. She's not thrilled about the rate. But she's thrilled about the home. The garden. The parking spot. The fact that her monthly housing cost is fixed for 30 years while her former landlord just raised rent on the next tenant by $250.
