Everyone above is right that it depends, so let me give you the thing that turns "it depends" into arithmetic you can actually do. Credit pricing does not improve smoothly. It improves in steps. On a conventional loan, your rate and fees are set partly by something called loan level price adjustments, which is a grid the agencies publish. Your credit score does not enter that grid as a number, it enters as a bucket. The buckets run roughly 620 to 639, 640 to 659, 660 to 679, 680 to 699, 700 to 719, 720 to 739, 740 to 759, 760 to 779, and 780 and up. The consequence is the useful part: If you are at 702, going to 718 is worth essentially nothing. Sixteen points of hard work, same bucket, same price. If you are at 698, going to 702 is worth real money, because you crossed into the next tier. Four points, one bucket, meaningful savings. So "should I wait" is the wrong question. The right question is: how far am I from the next breakpoint, and how long will it take to get there. Ask your loan officer this exact thing: "What is my middle score today, what is the next LLPA breakpoint above me, and what would my rate and fees be at that breakpoint versus today?" A competent loan officer answers that in five minutes with a real dollar figure. Then compare it to the cost of waiting. The cost of waiting is the part people underweight. While you improve your score you are paying rent, not building equity, and both prices and rates move on their own schedule with no regard for your credit timeline. If you are four points from a breakpoint and can get there in six weeks, wait. If you are forty points away and looking at a year, the math usually favors buying now and refinancing later. You can always change your rate. You cannot go back and buy a house at last year's price. Three more things worth knowing: There is a floor you do have to clear. Conventional needs 620. FHA needs 580 for 3.5 percent down. If you are below the floor for the program you want, this is not an optimization question, it is a qualification question, and you do have to wait. FHA prices differently. FHA mortgage insurance is set by loan-to-value and term, not by your credit score the way conventional LLPAs are. Which means at lower scores FHA is often the better deal, and above a certain score conventional pulls ahead. Ask your lender to price both side by side, same day, same numbers. That comparison alone is sometimes worth more than twenty points of score. Ask about a rapid rescore. If you are a few points short and you pay down a balance or clear an error, a lender can push corrected data through the bureaus in days rather than the usual thirty to sixty. You cannot initiate it yourself, the lender does. This is frequently what gets someone over a breakpoint without waiting months. One thing that will absolutely cost you: if you are close, do not open new credit, do not close old accounts, and do not let a balance report high right before your application. People spend six months building a score and then finance a couch three weeks before closing. An honest caveat since you posted this in 2021. The agencies have revised those pricing grids more than once since then, and rates are in a different place entirely. Do not work from any specific number you were quoted back then. Get current pricing. I am a real estate professional, not a lender or a credit counselor. The numbers above are structural, but your actual pricing comes from a loan officer running your file. I am Zoltan Peresztegi and I work in Los Angeles and the South Bay, including the Palos Verdes Peninsula. Clay County is outside my market. Message me and I will connect you with a strong local agent and a lender in northeast Florida at no cost to you. Find out how far you are from the next breakpoint. That single number decides this, and it takes one phone call to get. Zoltan
