Imagine a borrower with a 570 credit score, steady income, and enough savings for a down payment. On paper, at least two federal mortgage programs could work for that person. In practice, most lenders would decline the application before an underwriter ever saw it. That disconnect between what the government allows and what the mortgage industry actually approves is one of the most expensive blind spots in American homebuying, and as of spring 2026, nothing has closed it.
Below is what the federal rules say, where the real obstacles hide, and how to avoid wasting time and money on the wrong lender.
The Federal Minimums Are Lower Than Most People Think
Three federal agencies set the ground rules for the most common mortgage paths open to borrowers with lower credit scores. Their official positions are publicly documented and have not changed in recent years.
FHA loans: The U.S. Department of Housing and Urban Development publishes its Single-Family Housing Policy Handbook (4000.1), which governs FHA-insured mortgages. Under those rules, borrowers with credit scores between 500 and 579 can qualify with at least 10 percent down. At 580 or above, the minimum drops to 3.5 percent. These are regulatory thresholds baked into federal policy, not loose guidelines.
VA loans: The Department of Veterans Affairs takes a different approach. Its housing assistance pages confirm that the VA itself does not impose a minimum credit score for its home loan guarantee program. Instead, it guarantees a portion of each loan to reduce risk for private lenders, then leaves credit-qualification decisions to those lenders. The result: a veteran with a 580 score might get approved at one bank and rejected at another, even though the same federal guarantee backs both loans.
Conventional loans (Fannie Mae and Freddie Mac): The Federal Housing Finance Agency oversees both entities and publishes credit score policy materials describing how scores factor into loan approvals. Conventional loans generally carry a 620 minimum. But the FHFA has been working to transition Fannie Mae and Freddie Mac to newer scoring models, specifically FICO 10T and VantageScore 4.0. The agency originally targeted a rollout beginning in late 2025; as of spring 2026, the transition remains underway, and no final compliance deadline for all lenders has been published. The shift matters because the scoring model a lender uses can produce meaningfully different numbers for the same borrower. Someone who falls just short of 620 on one model might clear it on another.
The FHFA also publishes annual conforming loan limits that cap the loan size Fannie Mae and Freddie Mac can purchase in each county. Borrowers with lower credit scores tend to feel these limits more sharply because pricing adjustments and underwriting scrutiny both increase as loan size and borrower risk rise together. Once a loan exceeds the conforming cap, it enters jumbo territory, where standards tighten and options for marginal-credit applicants shrink fast.
One program often overlooked: USDA Rural Development loans, backed by the U.S. Department of Agriculture, serve eligible buyers in qualifying rural and suburban areas. The USDA does not publish a hard minimum credit score, though its automated underwriting system generally looks for 640 or above. Borrowers below that threshold can sometimes qualify through manual underwriting, making USDA loans another path worth exploring for buyers in eligible locations.
Where the Rules Get Murky
The federal minimums are straightforward enough. The confusion starts with everything layered on top of them.
Predatory marketing targets the most vulnerable borrowers first. The VA and the Consumer Financial Protection Bureau have jointly warned veterans about aggressive loan pitches promising effortless savings. That alert, first issued in 2014, focused on refinancing, but the same consumer-protection risks apply whenever a home loan is marketed with claims that sound unusually easy. Phrases like “guaranteed approval below 580” or “buy a home with no credit check” do not reflect any verified federal standard. At best, they describe niche programs loaded with compensating requirements. At worst, they are lead-generation bait for high-fee products. If a pitch sounds too simple, it almost certainly is.
Lender overlays are invisible until you apply. Every major mortgage originator sets its own internal credit score floor above the federal minimum. Some accept FHA borrowers at 580. Others quietly require 620 or even 640. No centralized, verified list of these overlays exists in the public domain, a transparency gap the CFPB has acknowledged in past supervisory work. Borrowers often discover a lender’s true cutoff only after submitting a full application, which triggers a hard credit inquiry and can temporarily lower their score. For someone hovering near a threshold, that small dip can be the difference between approval and denial.
Sub-620 approval rates are not tracked in useful detail. Neither HUD nor the VA publishes recent approval rates broken out specifically for borrowers below 620. Industry analysts sometimes cite figures, but those typically come from proprietary samples rather than official government data. Any claim about what percentage of sub-620 applicants actually close on a home should be treated as an estimate, not a fact.
The scoring-model transition is still in progress. Some analysts have suggested that VantageScore 4.0 could score certain consumers higher by incorporating utility and rent payment data, potentially helping borrowers near the 620 line. But the magnitude of that effect and the pace of lender adoption remain uncertain. Until the transition is complete and lenders are uniformly using the new models, borrowers are left guessing whether their scores will look better or worse under the system that ultimately evaluates them.
What Borrowers Below 620 Should Actually Do
The practical challenge is separating what the government permits from what a specific lender will approve. Here is how to approach it without burning time or credit inquiries.
Start with official sources, not search results. The strongest evidence comes directly from federal agency publications. HUD’s handbook, the VA’s housing assistance pages, and the FHFA’s policy documents represent binding program rules or official agency positions. When HUD says a score of 500 qualifies for FHA with 10 percent down, that is a regulatory fact. Institutional resources like HUD’s research arm at HUD User and the VA’s guidance for real estate professionals offer useful supporting context, though they do not always reflect the most current handbook amendments. Cross-reference everything.
Ask lenders to name their overlay before you apply. Before submitting a full application, ask each lender directly: “What is your minimum credit score for FHA (or VA) loans, and do you have additional requirements beyond the federal guidelines?” A lender who will not answer that question clearly is not worth the hard inquiry on your credit report. Get the answer in writing if possible.
Shop more than one lender. Because overlays vary widely, a rejection from one institution does not mean the program itself is closed to you. Borrowers below 620 benefit more from comparison shopping than almost any other group, precisely because the spread between the most and least restrictive lenders is so wide. The CFPB recommends getting quotes from at least three lenders, and for this credit tier, that advice is worth taking literally.
Use HUD-approved housing counseling. HUD maintains a network of approved housing counseling agencies that help borrowers understand their options, review their credit reports for errors, and map out realistic timelines for improving their position before applying. The service is free and underused relative to its value. A counselor can also help identify state and local down payment assistance programs, which vary by location and can meaningfully change the math for buyers with limited savings.
Be skeptical of easy promises. If a lender, advertisement, or social media post claims you are “guaranteed” approval with a sub-620 score, treat that as a red flag. Federal programs create real opportunities for lower-credit borrowers, but no one can guarantee approval because the final decision always rests with a private lender applying its own standards on top of the government’s rules.
Know the timeline for credit improvement. For borrowers who fall short today, the gap may be smaller than it feels. Paying down revolving balances, correcting reporting errors, and letting recent hard inquiries age can each move a score by meaningful increments within a few months. A HUD-approved counselor can help prioritize which actions will have the biggest impact for a specific credit profile.
Federal mortgage programs genuinely do extend below 620, and for many borrowers, that opens a door that feels permanently shut. But the distance between the government’s floor and a lender’s actual threshold is where confusion, wasted applications, and unnecessary costs pile up. The borrowers who close that gap fastest are the ones who know exactly what the rules say and refuse to let any lender hide the ball on where they diverge.
