A 620 credit score is one of those numbers that sits exactly on the line. It is good enough that most lenders will take your call and pull your file seriously. It is not good enough to get you anywhere near the best rate on the sheet. Knowing which lenders work comfortably at 620, and which ones quietly decline it, will save you a string of pointless applications and hard inquiries.
The short version: plenty of lenders will approve a 620. You will pay for the privilege, usually somewhere between a quarter and three-quarters of a percentage point above what a 760 borrower gets for the same house. Here is how that plays out in practice.
What a 620 Credit Score Actually Unlocks
Fannie Mae and Freddie Mac both set their minimum at 620 for conventional loans, which means nearly every lender that sells loans to them follows the same floor. So 620 is the entry point for conventional financing, not the middle of the pack. The pricing tiers get meaningfully worse as you drop from 760 down to 620, and the last few points before the floor are the most expensive ones you will ever buy.
FHA is a different story. FHA lenders can go down to 580 with 3.5% down and 500 with 10% down, so a 620 clears FHA with room to spare and usually gets automated approval without extra documentation. VA and USDA do not publish a hard score floor, but most participating lenders want 620 for VA and around 640 for USDA before their automated systems will issue an approval.
One practical detail people miss: 620 is often the cutoff between automated underwriting and manual underwriting. Above it, a computer makes the decision in minutes. Below it, an underwriter reads every page, and the file takes longer and asks for more paperwork. If your score dips below 620 before closing, expect the process to slow down considerably.
Which Lenders Work Well at 620
Non-bank mortgage lenders
Companies like Rocket Mortgage, PennyMac, Newrez and Freedom Mortgage live inside agency guidelines and price aggressively at 620. They are built for volume, they follow the Fannie and Freddie grids closely, and they rarely add extra credit overlays on top. If your file is clean apart from the score, this is often where the sharpest quote comes from.
Banks and credit unions
The big national banks tend to layer their own minimums on top of the agency floor, and several set them at 640 or 660. Regional banks and credit unions that keep loans on their own books have more room to bend, especially if you have banked with them for years or you are borrowing a modest amount relative to the property value. Ask directly whether they portfolio the loan or sell it.
FHA-focused and specialty lenders
Lenders who specialise in government-backed loans are comfortable with lower scores and thinner credit files. They handle FHA files all day and know exactly which compensating factors underwriters will accept.
Mortgage brokers
A broker with wholesale access can price your file across 10 or 15 lenders in an afternoon without adding a single inquiry, since wholesale rate shopping is done on soft credit. That matters at 620, because the spread between the best and worst quote on the same day is often larger than the gap between score tiers. If your credit history has real blemishes, it is worth reading about home loan lenders for bad credit before you start calling, since the lender list changes fast as the score drops.
Lenders that will generally work with a 620 include:
- Large non-bank retail lenders operating inside Fannie and Freddie guidelines
- FHA specialists who handle 580 to 640 files every week
- Credit unions with portfolio lending programs and relationship pricing
- Wholesale lenders reached through a broker
- Non-QM and bank statement lenders, if you have compensating factors and can absorb an 8% to 11% rate
The Real Cost of Borrowing at 620
Mortgage pricing is driven by loan-level price adjustments, which are fees the agencies charge lenders based on credit score, down payment and loan type. At 620 with a small down payment, those adjustments can run somewhere between 1.5% and 3% of the loan amount. On a $300,000 loan, that is $4,500 to $9,000, either paid upfront as discount points or folded into a higher rate.
A concrete comparison. A 760 borrower might be quoted 6.5% on a $300,000 thirty-year fixed loan, which is a principal-and-interest payment of about $1,896. A 620 borrower on the same day might see 7.25%, or roughly $2,047. That is $150 a month, and about $54,000 in extra interest if the loan runs its full term. Refinancing later can shrink that gap, but only if your score improves and rates cooperate.
FHA Versus Conventional at 620
This is the comparison worth running properly, because the cheaper option is not always the obvious one.
Conventional at 620 costs more in loan-level pricing but comes with private mortgage insurance that drops off automatically once you hit 78% loan-to-value, and you can request removal at 80% with an appraisal. FHA is easier to qualify for and usually carries a lower rate, but it charges a 1.75% upfront premium plus annual mortgage insurance that, with 3.5% down, typically stays for the life of the loan. On a long hold, conventional often wins. On a short hold where you plan to refinance in three to five years, FHA can be cheaper.
Get both quotes on the same day with the same loan amount. That single comparison is worth more than any advice column, including this one.
Compensating Factors That Offset the Score
Underwriters do not look at credit score in isolation. A 620 with a 34% debt-to-income ratio and six months of reserves is a materially different file from a 620 with a 48% DTI and nothing in the bank. The factors that carry the most weight:
- Down payment above the minimum. Ten percent down instead of 5% can pull the pricing adjustment down a full tier.
- Low DTI. Keeping total debt payments under 40% of gross income opens doors that a 48% ratio closes.
- Cash reserves. Two to six months of housing payments in a verifiable account.
- Clean recent history. No late payments in the past 24 months carries real weight, even if older derogatory marks exist.
- Stable employment. Two years in the same field, with a documented raise or promotion, helps.
If you are carrying older collections or a recent late payment, it helps to understand how lenders treat files further down the scale. The approval standards described for lenders who approve a 580 credit score give a realistic picture of how much a derogatory mark actually costs you.
Adding 20 to 40 Points Before You Apply
Small score improvements move you between pricing tiers, and the tiers are chunky. Getting from 620 to 640 can shave 0.25% off the rate. Getting to 660 can shave more.
The fastest lever is credit utilisation. Paying a revolving balance down before the statement closing date, rather than the due date, is what actually reports to the bureaus. Dropping from 60% utilisation to under 10% can add 30 or 40 points in a single billing cycle.
Next is error correction. Pull all three reports and look for accounts that are not yours, balances reported twice, or late payments listed on accounts that were current. A rapid rescore, arranged through your lender, can update the file in three to five business days rather than the usual 30 to 45. If you are sitting just under a lender minimum, ask about it directly. The same discipline applies whether you are targeting 620 or looking at mortgage lenders for a 600 credit score, where a handful of points often separates an approval from a decline.
Two things not to do: close old credit cards, which cuts your available credit and raises utilisation, and open a new card or car loan in the six months before applying. Both cost points at exactly the wrong moment. A goodwill letter asking a creditor to remove a single isolated late payment occasionally works, and it costs nothing to try.
What to Ask on the First Call
Most of the difference between a good and a bad outcome at 620 comes down to the questions you ask before anyone pulls your credit.
- What is your minimum credit score for this specific loan program, and do you have overlays above the agency guidelines?
- Can you send me a full Loan Estimate with the rate, points, origination fee and all third-party costs, not just a rate quote?
- Does your pricing change if my score moves during processing, and will you re-price the loan if it improves?
- What DTI limit and reserve requirement do you apply to a 620 file?
- Is there any lender credit available in exchange for a slightly higher rate, and what does that do to the payment?
Ask each of those to three lenders and compare the Loan Estimates side by side on the same day. Rates move daily, so a quote from Tuesday against a quote from Friday is not a real comparison. The lender who answers all five clearly, without dodging, is usually the one whose closing costs also match the estimate at the end.
