Two conventional-loan questions get searched constantly and almost never answered together, even though they're really the same underwriting conversation: "what credit score do I need" and "what condition does the home need to be in." A strong credit score can still hit a wall if the property itself doesn't pass the appraisal's condition review — and a borrower who assumes any livable house will do is often surprised by a repair request late in escrow. Here's how conventional financing actually evaluates both the borrower and the property.
Conventional loan minimum credit score
Conventional loans generally start around a 620 credit score, following guidelines set by Fannie Mae and Freddie Mac, with meaningfully better pricing and loan-to-value flexibility available as the score climbs higher. That 620 figure is a general starting point, not a universal cutoff:
- 620 is where conventional financing generally becomes available under standard Fannie Mae/Freddie Mac guidelines, but individual lenders can and do set their own overlays above that floor depending on the rest of the file.
- Score tiers affect pricing, not just eligibility. A 620 borrower and a 760 borrower can both qualify for the same loan program, but typically at meaningfully different pricing and, on some loan-to-value combinations, different mortgage-insurance costs.
- The score doesn't stand alone. Underwriters weigh it alongside debt-to-income ratio, employment history, and reserves. A 620 score paired with a strong overall file can qualify more easily than the same score paired with a thin file.
If your score is under roughly 620, that doesn't necessarily rule out homeownership — it's often exactly the scenario where FHA financing, with its lower published floor, becomes the stronger starting point instead. If your score is close to 620 but not quite there, read why one "no" doesn't end your home search. None of the figures above are a Choice Home Mortgage guarantee of approval at any specific score — they're the general shape of how conventional guidelines work.
How conventional credit requirements compare to FHA
Conventional's roughly 620 starting point sits above FHA's published 580 floor for 3.5%-down financing, which is exactly why FHA is often the first conversation for a borrower whose credit is still being rebuilt. But the comparison isn't purely about which program lets you in at a lower score — it's about the tradeoffs on the other side. Conventional financing generally requires stronger credit but offers mortgage insurance that can be cancelled once you reach 78–80% loan-to-value; FHA accepts a lower score but its mortgage insurance can last the life of the loan on a low down payment. A borrower sitting right around 620–640 is often a genuine toss-up between the two programs, and the right answer depends on the full file, not the credit score alone. See our FHA loan requirements in California piece for the fuller comparison.
What actually moves the needle beyond the score itself
A credit score is a snapshot; underwriters look at the fuller credit picture too. Recent late payments read differently than an old, resolved issue. A thin credit file (few open accounts, short history) can sometimes be harder to underwrite than a slightly lower score with a long, consistent payment record. Collections, judgments, and how recently a bankruptcy or foreclosure occurred all factor in separately from the score number itself, with their own seasoning timelines under Fannie Mae and Freddie Mac guidelines. This is exactly the kind of file-specific nuance that a single published minimum score can't capture, and it's worth a real conversation rather than assuming a number alone tells the whole story.
Conventional loan property condition requirements
The property itself has to clear its own bar, independent of the borrower's credit. Fannie Mae's Selling Guide (section B4-1.3-06, Property Condition and Quality of Construction of the Improvements) sets out a condition-rating framework the appraiser applies, ranging from C1 (new or like-new construction) to C6 (significant deferred maintenance or deficiencies affecting safety, soundness, or structural integrity). The practical rule that matters most to a buyer:
- Properties rated C1 through C5 are generally eligible for financing in "as-is" condition, provided any deficiencies are minor and don't affect the property's safety, soundness, or structural integrity.
- A property rated C6 is not eligible for delivery to Fannie Mae as-is. Deficiencies affecting safety, soundness, or structural integrity have to be resolved — typically via repair — bringing the property to at least a C5 rating before the loan can close on a Fannie Mae-eligible basis.
Freddie Mac maintains a comparable property-condition framework for loans it purchases, though the specific rating language and thresholds aren't necessarily identical to Fannie Mae's — which framework applies depends on which agency's guidelines the lender is underwriting to. Either way, the underlying principle is the same: cosmetic wear and minor deferred maintenance generally don't block conventional financing, but issues touching the structure, roof, foundation, electrical, or plumbing systems typically do, until they're addressed.
What the appraisal actually checks
A conventional appraisal does two jobs: it establishes the property's market value, the number a lender bases the loan on, and it documents the property's condition against the framework above. The appraiser isn't a home inspector and isn't performing an exhaustive systems check — but a visible issue (a sagging roofline, exposed wiring, obvious water intrusion, an inoperable HVAC system) will typically get flagged and can trigger a required repair, a "subject to" appraisal contingent on that repair, or in some cases a lender declining to move forward until it's resolved. This is a different standard than a full home inspection, which buyers should still get independently for their own protection — the appraisal protects the lender's collateral value, not the buyer's overall due diligence.
How condition interacts with down payment and loan-to-value
Property condition and loan-to-value aren't entirely separate underwriting questions. A property with condition issues that would otherwise be workable at a lower loan-to-value can sometimes face additional scrutiny at a very high loan-to-value (a low down payment), because the lender's collateral position is thinner in that scenario. This doesn't mean a low-down-payment purchase can't buy a property with cosmetic wear — it generally can — but a property closer to the C5/C6 boundary is worth extra caution on a minimal-down-payment purchase specifically, since there's less room for the numbers to move if a repair negotiation falls through. Pairing our companion piece on conventional down payment tiers with the condition guidance here gives the fuller underwriting picture for a specific purchase.
What a low appraisal (value, not condition) means for the file
A separate but related appraisal outcome worth understanding: the appraisal can come back with a value lower than the purchase price, independent of the property's condition rating. If that happens, the loan amount a lender will approve is generally based on the lower of the purchase price or the appraised value — which means a low appraisal can require the buyer to bring additional cash to cover the gap, renegotiate the purchase price with the seller, or in some cases dispute the appraisal with supporting comparable sales. This is a different issue entirely from the condition-rating framework described above, though both can surface from the same appraisal report, and it's worth knowing the two are separate problems with separate solutions before assuming a low appraisal number is a condition issue or vice versa.
Second homes and investment properties: a different credit and condition bar
Everything above describes a primary-residence purchase. Conventional guidelines generally apply a higher credit-score floor and different down-payment minimums for a second home or investment property than for a primary residence — and property-condition standards apply the same way regardless of occupancy, since the collateral risk to the lender doesn't change based on who lives there. If you're buying a rental property specifically and traditional income documentation is a poor fit, our DSCR loan program qualifies the property on its rental income rather than your personal credit and income profile the same way conventional financing does — worth a look if the conventional credit or documentation bar doesn't fit your situation.
Buying a fixer-upper with conventional financing
A property with real deferred maintenance doesn't automatically disqualify a conventional purchase, but it does change the process. Common paths when a property comes back with condition issues:
- Negotiate repairs into the purchase contract before closing, so the seller resolves the flagged items and the appraiser can re-verify the condition.
- Renovation-specific financing (such as Fannie Mae's HomeStyle Renovation program) that finances the purchase and the repair costs together, structured specifically for properties that wouldn't otherwise pass as-is.
- Walk away from that specific property if the repair scope is larger than the deal makes sense for, and look elsewhere.
Which path fits depends on the specific deficiencies, the seller's willingness to negotiate, and how the numbers work with repairs factored in — not something to assume in either direction before getting a real read on the property.
What to do before the appraisal, not after
Because a condition surprise late in escrow is stressful and time-pressured, the better approach is addressing likely condition issues before they become an appraisal problem:
- Get a general home inspection early — ideally within your contract's inspection contingency window — even though it's separate from the appraisal. An inspection often surfaces the same issues an appraiser would flag, but earlier and in more detail, giving you time to negotiate before the appraisal is even ordered.
- Ask your agent directly about any known issues with the specific property, including anything disclosed in seller documents, before writing an offer on a property with visible deferred maintenance.
- Budget contingency room if you're purchasing a property with any known condition question — both in timeline and in cash, in case a negotiated repair credit doesn't fully cover the cost.
None of this replaces the lender's own review, but it means the appraisal confirms what you already expected rather than introducing a new problem on a compressed closing timeline.
A worked illustration
As a purely illustrative example with round, hypothetical numbers — not a real deal, not a program promise — picture two borrowers each looking at a $650,000 property. One has a 640 credit score and the property appraises at a C3 condition rating with only cosmetic wear; that file moves through underwriting on the standard conventional track. The other has the identical 640 score, but the property appraises at a C6 rating due to an aging roof with active leaks; that file needs the roof addressed — either by the seller before closing or through renovation-specific financing — before it can close as a conventional loan. Same borrower profile, same purchase price, two very different paths, because the property's condition, not the buyer's credit, was the variable that mattered.
What repairs typically get requested, and who pays
When an appraisal flags a condition issue, the repair itself is negotiated between buyer and seller as part of the transaction — the lender doesn't dictate who pays, only that the deficiency gets resolved before the loan can close on a Fannie Mae-eligible basis. Common negotiated outcomes include the seller completing the repair before closing, the seller crediting the buyer cash at closing to complete it afterward (where the lender's guidelines allow this structure), or a price renegotiation that accounts for the cost. Which path makes sense depends on the specific repair, how much leverage each side has in the negotiation, and how the timeline lines up with the closing date — a repair that requires a permit or a specialist contractor can take longer than a purchase contract's contingency period allows, which is worth flagging early rather than discovering it late in escrow.
Rural and older-home considerations in California
Two property situations that come up often enough in California to be worth naming directly: an older home with original electrical or plumbing systems, and a rural property with a well or septic system instead of municipal utilities. Neither automatically fails a conventional appraisal, but both draw closer scrutiny than a newer, standard-utility home. An older home's systems are evaluated on function and safety, not age alone — a 1960s electrical panel that's been properly maintained and poses no hazard is a different appraisal outcome than the same-era panel with visible deterioration. A well or septic system typically needs its own separate inspection and certification, distinct from the general appraisal, confirming it meets local health-department standards and has adequate capacity — a requirement that has nothing to do with credit score and everything to do with the property itself.
The short version
Conventional financing evaluates two things independently: the borrower, generally starting around a 620 credit score with meaningfully better terms as it climbs, and the property, which has to clear Fannie Mae's condition-rating framework — C1 through C5 generally fine as-is, C6 requiring repair to at least C5 before the loan can close. A strong score doesn't override a property that fails the condition check, and a great property doesn't override a credit profile that doesn't fit the guidelines. Both have to line up, and neither is something to assume from a distance before someone has actually looked at the specific numbers and the specific address.
