Credit Score Below 620? Here Is How You Get Above It Before You Apply

This is milestone 14 of The Essential First-Time Homebuyer Roadmap, and it is where the credit work pays off. The earlier milestones handed you the fast-track action steps that lift your score and the do not do's that protect it. This milestone tells you the number to aim for and why 620 is the line that matters. If your scores are sitting below 620, the goal is not to stress about where you are today. The goal is to get above 620 for FHA or Conventional, and a 30 to 50 point move over 2 to 4 months is not uncommon once you are working the plan.

The Number That Matters: 620

Every loan program draws its own line in the sand, but for the loans most first-time buyers use, FHA and Conventional, 620 is the line that matters. Get above it and the door opens wider. Stay below it and you are pushing an uphill grade. That is why this milestone has one job: get you above 620 before you ever apply. It is not a magic number that makes the rest of the process effortless, but it is the threshold that makes FHA and Conventional realistic, and it is the number a lender anchors to the first time they look at your file. If you want the full picture of how each loan program sees your score, the FHA vs Conventional vs VA comparison walks through where each one draws its lines, and the mortgage hub compares every program a buyer can use once you are above the line.

The Truth About FHA Below 620

Here is the honest version. You can theoretically get approved for FHA below 620, but it gets harder the lower you go, and the deeper you drop, the more the lender has to justify your file to the automated underwriting system. Some lenders will not touch a file below a certain number no matter what, and the ones that will tend to pile on conditions and slower reviews. So the question is not whether it is possible. The question is why risk it when moving your score is not hard once you have identified the action steps. A buyer at 619 and a buyer at 621 can look nearly identical on paper, but the one at 621 is negotiating from a position of strength.

How Far Can You Actually Move the Needle?

Let me give you a realistic target instead of a fantasy. Using the action steps and avoiding the do not do's, a 30 to 50 point increase over 2 to 4 months is not uncommon. That is not a promise for every single file, and nobody can guarantee points, but it is a real, observed range from files that get worked properly. Think about what that does for a buyer sitting at 590. Two to four months of disciplined work puts them at 620 to 640, right in the range where FHA and Conventional get real. It is not a 100 point jump overnight. It is steady, structured work over a realistic window, and it is exactly the runway this Roadmap was built around.

The Action Steps That Move the Number

The fastest work comes from a short list of moves that are legal, repeatable, and proven. Reduce revolving balances to 30% of your credit limit, and 10% for maximum impact. Ask a long-standing credit card relationship to increase your credit limit. Add an authorized user with low utilization. Have a third-party service add your rent and utility history to your report. And dispute errors plus collection items you already paid. I spelled each of these out in the fast-track steps post, and they are the engine behind the 30 to 50 point move. The how to raise your credit score guide covers the same ground with the specifics in one place.

The Do Not Do's Protect Every Point You Gain

The other half of the equation is not undoing the work. The do not do's are the mirror image of the action steps: do not open new accounts while a purchase is in motion, do not pay off installment loans early, do not contest a collection that is correct, and do not close a $0 balance card. One careless move can erase a month of gains. I walk through all four in milestone 13, and if you are below 620 right now, they matter even more, because you have less room to absorb a mistake. The buyer who adds points and then protects them is the buyer who shows up at pre-approval with a number that actually holds up.

If Your Scores Are Below 600 Right Now

Do not fall into an emotional funk if your scores are below 600. I know it is easy to look at a number in the 500s and feel like the whole process is out of reach. It is not. The same plan applies, it just needs a longer runway and a steadier hand. The action steps still work, the do not do's still protect you, and the goal is still the same line: get above 620 for FHA or Conventional. A buyer who starts at 580 with four months of discipline gets to a very different conversation than a buyer who starts at 600 and does nothing. The score is a starting point, not a verdict, and the buyers who treat it as a project with a deadline are the ones who walk into pre-approval with options.

The San Antonio Angle

In the greater San Antonio market, this timing lines up with the countdown from milestone 1. Month six is when you pull your real scores and find out where you actually stand. Months five and four are when you run the action steps and hold the do not do's. By month three, you hand a stronger file to Lawrence and Patricia, and the pre-approval conversation gets a lot more comfortable. Buyers here often try to compress this into a few weeks, and they end up waiting longer or starting over. The buyers who treat the 2 to 4 month window as part of the plan are the ones who close on their own timeline.

Credit score requirements vary by loan program and by lender, and every underwriting review applies its own standards. No lender can promise a specific score outcome, so confirm the realistic plan for your exact file and timeline with your loan officer before relying on any result.
