In the housing market, timing is everything, but with so many volatile economic variables — from mortgage rates to gas prices — homebuyers can feel like they’re stuck playing against a glitchy shot clock.
Realtor.com provided some clarity to anxious homebuyers on Wednesday, outlining three strategies to rate-proof their budgets based on 26 years of mortgage data. The portal’s researchers found that consumers should prepare for fluctuations of 50 basis points (or 0.50 percent) to 100 basis points (or 1 percent) in either direction within the next three to 12 months.

“Rate-proofing for potential buyers right now is super important because they can’t build assumptions for their finances on the chance that interest rates may go down,” Home Qualified President Ralph DiBugnara told Realtor.com. “They need to be comfortable with the monthly payment, whether the rates go down or up, and build their budgets around that. This is not a market where you can time for the best rate and the best price that’s the best fit for you.”
The report laid out three strategies, based on the assumption that a homebuyer has a monthly mortgage budget of $2,000, and they want to buy within the next 12, six or three months:
- Buyers should anticipate rates shifting 100 basis points in either direction, giving them a potential range of 6 to 8 percent based on the current average 30-year fixed mortgage rate of 6.95 percent. A 1 percent rate increase would decrease their buying power by $28,000 to $272,000, while a 1 percent rate decrease would boost it by $33,000 to $333,000.
- Buyers should prepare for rates to shift 75 basis points in either direction. A 0.75 percent rate increase would drop their buying power by $21,000 to $279,000, while a 0.75 percent rate decrease would expand their budget by $24,000 to $324,000.
- Buyers should plan for rates shifting 50 basis points in either direction. A 0.50 percent rate increase would chop their budget by $15,000 to $286,000, while a 0.50 percent rate decrease would boost what they can buy by $16,000 to $316,000.
The report said homebuyers who want to make a purchase by year’s end have it the easiest, while buyers working on a longer timeline are more vulnerable to any number of housing market and macroeconomic changes that could occur.
No matter which group a homebuyer falls into, Realtor.com suggested building a budget buffer of at least $130 per month, a figure that’s based on a median-priced property of $429,500 with a 10 percent down payment, and a 7 percent mortgage rate.
In that scenario, the monthly principal and interest currently total $2,542, and a $130 buffer allows them to absorb a 0.50 percent rate increase or decrease, which would shift the payment by $129 more or $127 less.
Homebuyers will get a better idea of what they’re facing in October, after the next Federal Open Market Committee (FOMC) meeting on Oct. 28.
At its Sept. 16 meeting, the Fed increased the federal funds rate (the short-term rate) by 25 basis points to 4 percent at the top of the range. Currently, the CME FedWatch has put the probability of another hike at 73.1 percent and the probability of the Fed holding steady at 26.9 percent.
The federal funds rate impacts how banks and financial institutions set their rates, including mortgage rates. It’s important to note that a change in the federal funds rate does not guarantee that mortgage rates will move in tandem; however, rates’ quick ascent over the past week hasn’t been comforting.
From Sept. 22 to Sept. 23, the 10-Year Treasury Note — another mortgage rate indicator — increased 0.014 percent to 5.074 percent. That one-day jump has led analysts to predict that rates could reach 7.28 percent by next week.
Notable one-day jump
IF this holds, and yesterday’s spread remains, we’re looking at another 52-week high for the average 30-year fixed mortgage rate—likely coming in around 7.28% https://t.co/PlGdvdOXpv

“Mortgage volatility is a constant feature of the homebuying process, no matter the state of the economy,” Realtor.com’s report read. “What a buyer can afford continuously shifts: a dream home that was within budget just a week ago can suddenly become out of reach today depending on rate ups and downs. But experts maintain that following these guidelines makes these shifts more predictable, allowing shoppers to be better prepared and more empowered to take control of their homebuying.”
