Mortgage
Rate shopping, credit scores and down payment timing can shift buying power by $28,400
By Real Estate Wire Staff, . Real Estate Wire.
Mortgage rates have crossed 7% for the first time since January 2025, but Realtor.com's economics team reports that the headline figure obscures a wide band of actual outcomes. Analyzing 2025 Freddie Mac loan data, senior economist Jake Krimmel found that the middle 80% of borrowers secured rates spanning nearly a full percentage point within a single month. Realtor.com put the spread at 93 basis points, which on a $2,000 monthly principal-and-interest budget works out to approximately $28,400 in purchasing power.
The analysis identifies three levers: credit score, down payment size, and lender selection. They differ sharply in how quickly a buyer can act on them.
On credit scores, the Realtor.com data shows that rate benefits arrive in tiers rather than as a smooth curve. Crossing the 700 threshold cuts about 5.47 basis points; moving past 720 delivers the largest single-step improvement at 5.51 basis points; the 740 mark shaves off 4.91 basis points; and gains above 780 shrink to 2.56 basis points. In practical terms, lifting a score from 680 to 720 saves 11 basis points and adds roughly $3,200 in purchasing power, while a full climb from below 640 to above 780 saves more than 32 basis points and adds about $10,100. Sarah DeFlorio, vice president of mortgage banking at William Raveis Mortgage, told Realtor.com that "focusing on keeping a good credit score will provide the best benefit for getting a better rate and mortgage terms overall." Audi Garner, founder of HELOCpedia, added that pricing is tiered, so moving from a 700 to a 740 score can improve the rate more than adding a few percentage points to the down payment.
Down payments follow a similar tiered logic. Crossing the 10% threshold produces the largest rate benefit below 20%, at 5.5 basis points. Between 10% and 20%, the rate barely moves, though private mortgage insurance costs rise at lower levels. The 20% mark itself, Krimmel notes, is not a rate milestone on its own: the step from 15%-19% to 20% down is worth only 0.7 basis points, though it does eliminate private mortgage insurance. Above 20%, meaningful rate reductions continue up to 35% down before flattening. Moving from 20% to 40%-plus down lowers the rate by 17.5 basis points, worth about $5,400 in purchasing power. Andy Restrepo of A&D Mortgage told Realtor.com that a buyer with 12% to put down is better off putting down 10% and using the remaining 2% to pay off debt, since the rate pricing is the same at both levels and reducing debt may lift the credit score further.
Lender selection is the fastest lever and, according to the Realtor.com analysis, potentially the most powerful in the short run. Brokers and correspondent lenders priced 5 to 6 basis points below traditional retail lenders on average in 2025 data. Switching from a retail lender that originates at 2.1 basis points above the headline rate to a top competitive lender pricing 17 basis points below average saves 19 basis points and adds roughly $5,800 in purchasing power. Realtor.com notes that is double the rate benefit of moving a credit score from 690 to 720, and it can be done immediately. DeFlorio cautioned, however, that the lowest-rate lender is not always the right choice: lenders with the sharpest pricing are often the most backlogged, and slow turnaround times can kill a deal with a tight closing window.
The practical implication is sequencing. Credit score improvements and down payment accumulation are long-horizon moves that reward buyers who plan well in advance. Lender shopping is the one action available to a buyer already under contract. For professionals advising clients in a 7%-rate environment, the Realtor.com framework suggests the conversation should start with where the client's credit score sits relative to the 700, 720 and 740 thresholds, then move to whether their cash reserves are better deployed as a larger down payment or as debt reduction, and only then turn to rate shopping across lender types.
What the analysis does not address is how rate variation interacts with local market conditions, including how quickly sellers in specific markets are willing to negotiate on price or offer concessions that offset financing costs. That remains a deal-by-deal judgment.
