FHA, VA, USDA and conventional (Fannie Mae/Freddie Mac) loans all treat a septic system and private well as acceptable, provided the system is functioning, located on the subject property (or covered by a recorded easement/maintenance agreement if not), and meets the local or state health authority's requirements. The programs differ in how prescriptive they are and how much documentation they typically require; none of them ban septic or well properties outright.
FHA's baseline preference is connection to public water and sewer where that's feasible at reasonable cost. Where it isn't, an existing individual well and septic system is acceptable if it's functioning properly and meets the local health authority's requirements; the handbook also sets minimum separation distances between the well, the septic tank, the drainfield and the property line, with the local health authority's own standard controlling where it is stricter than HUD's. If the appraiser sees signs of septic failure, the lender must order a further inspection before the loan proceeds. (HUD Handbook 4000.1, Property Acceptability Criteria.)
VA's Minimum Property Requirements call for a reliable, safe water source and sewage disposal that functions without backups, odors, or surfacing effluent. A private well's water typically needs documented potability against local or federal health standards. VA updated Chapter 12 ("Change 46") for appraisals ordered on or after May 1, 2026, streamlining some of the older prescriptive language in favor of deferring to local code compliance and the appraiser's observation of function.
USDA guaranteed loans require the lender to obtain a septic evaluation. The system must sit entirely on the subject property (or be covered by a recorded easement and maintenance agreement), meet applicable state or local health authority requirements, and have the capacity to handle the home's wastewater without creating a nuisance or health hazard. For well-to-septic separation distance, USDA's own handbook points to HUD 4000.1's standard or to whatever the local/state health authority finds acceptable, rather than setting an independent number. A shared well is limited to four living units unless separately approved, and each dwelling needs its own shutoff valve.
Conventional loans require utilities that meet community standards; where public water/sewer isn't available, a private well and septic system are acceptable if located on the subject property (or accessible under an adequate, legally binding off-site agreement). The appraiser is required to note anything affecting the value or marketability of the property related to the well, septic, or water supply, and where a lender has reason to suspect well-water contamination, obtaining a water certification is treated as sound practice.
None of the four sets a blanket rule that a septic-served or well-served property is ineligible. All four ultimately anchor to the same idea: the system has to actually work, it has to sit on land the borrower controls (or has a binding right to use), and it has to satisfy whatever the local or state health authority requires. We are intentionally not repeating specific foot-distances or dollar figures beyond what's cited above; get the current number from the handbook itself or from your lender, since local health authority rules frequently supersede the national baseline anyway.

Yes. FHA accepts a functioning individual septic system that meets local health authority requirements when public sewer isn't feasible at reasonable cost, subject to HUD Handbook 4000.1's property acceptability standards.
VA's Minimum Property Requirements (Pamphlet 26-7, Chapter 12) require sewage disposal to function without backups, odor or surfacing effluent, and give the appraiser and lender discretion to require an evaluation, service record, or permit depending on what's observed and the local jurisdiction.
USDA (HB-1-3555, Chapter 12) requires a lender-obtained septic evaluation and generally defers to HUD 4000.1 or the local/state health authority for well-to-septic separation, rather than setting its own separate distance standard.
Yes. Fannie Mae's Selling Guide (B4-1.3-04) requires the well/septic to be on the subject site (or covered by a binding access/maintenance agreement) and requires the appraiser to flag anything affecting value or marketability tied to the water or sewage system.

Laws, lender overlays and local ordinances change; confirm current requirements with the county or state agency, your lender, and a licensed inspector before you rely on this for a closing.
