Which inspections FHA, VA, USDA, and conventional loans can trigger, and how to flag them before they reach underwriting

This “realtor cheat sheet” is built for agents working with buyers across Asheville, Hendersonville, Black Mountain, Weaverville, Brevard, Cashiers, and the surrounding Buncombe, Henderson, and Madison County markets, where private wells and septic systems are common.

Every loan program comes with its own property requirements, and the specifics depend on the loan type your buyer is using and whether the property is served by a private well, a septic system, or both. This cheat sheet breaks down which inspections typically apply to which loan programs, so you can flag potential issues with your buyer and their lender before the file reaches underwriting rather than after.

Exact requirements can vary by state, county, and individual appraiser findings, so when a property looks like it might be an exception, your loan officer can help you work through it early, on day one rather than the week before closing.

Quick Reference: Inspections by Loan Type

Loan Type	Well Water Test	Septic Inspection	Termite/Pest Inspection
Conventional	Only if the appraiser flags a concern	Only if the appraiser flags a concern	Not automatically required
FHA	Required for any private well	Required if well-to-septic distance can’t be confirmed	Not required nationwide; common by state, local jurisdiction, or lender
VA	Required for any private well	Required if well-to-septic distance can’t be confirmed	Required in most of the country
USDA	Required for any private water source	Required only if the appraiser can’t verify distance or sees an issue	Not required federally; many states require it independently

Why Inspection Requirements Catch Agents Off Guard

Many additional inspection requirements aren’t identified until the appraisal is complete and the file has moved into underwriting. An appraiser evaluating a property with a private well and septic system, for example, checks the distance between the two and flags the file for a water test or septic evaluation if that distance doesn’t clearly meet the loan program’s standards. Because these findings often surface after your buyer is already under contract, an inspection that wasn’t part of the original plan can add real time to a purchase that otherwise looked ready to close. This comes up often on a buyer’s first VA loan on a property with private utilities, a common scenario in Western North Carolina’s more rural markets. Knowing which loan programs are more likely to require these steps helps you set realistic expectations with your buyer from the start.

Private Wells and Septic Systems: The Most Common Trigger

Properties served by a private well, a septic system, or both are the source of most additional inspection requirements, regardless of loan type.

• Well water test: Required on FHA, VA, and USDA loans whenever a property relies on a private well. Conventional loans typically don’t require a water test unless the appraiser identifies a specific concern.
• Septic inspection: Not automatically required on any loan type. It becomes a condition when the appraiser can’t confirm an adequate distance between the well and the septic system, observes a visible sign of a problem such as standing water or unusual vegetation over the drain field, or when state or local regulations require an inspection on every property transfer.
• Well-to-septic distance: Most local health departments require 50 to 100 feet of separation between a well and a septic system. VA doesn’t publish its own fixed distance and instead defers to that same local health department standard. FHA’s distances vary by component, generally 50 feet from the tank and 100 feet from the drain field (sometimes 75, depending on the jurisdiction). On a smaller lot, confirm the applicable distance early, before it becomes an appraisal condition.

Inspection Requirements by Loan Type

Conventional Loans

Conventional loans offer the most flexibility of the four major loan types. A well or septic inspection is typically required only if the appraiser identifies a concern, or if the lender’s specific guidelines call for one. A termite inspection isn’t automatically required, though many buyers order one regardless of loan type.

FHA Loans

FHA loans apply stricter standards once a private well or septic system is involved.

• A water quality test is required for any property served by a private well, with results measured against EPA or local health department standards.
• If the appraiser can’t confirm that the well and septic system meet minimum distance requirements, a septic evaluation will likely be added as a condition of the loan.
• A termite inspection isn’t required nationwide, but it’s commonly required by state law, local jurisdiction, or lender discretion, particularly in areas with a known risk of termite activity.

VA Loans

VA loans are governed by the VA’s Minimum Property Requirements, which apply the most scrutiny to private wells and septic systems of the four loan types.

• A water quality test is required for any property with a private well.
• The appraiser verifies the distance between the well and septic system as part of the appraisal, measured against the local health department standard VA defers to. If the distance falls short, the file may require a variance or remediation before closing.
• A termite or wood-destroying insect inspection is required in most of the country for VA loans, with limited exceptions in a small number of low-risk areas. This is one of the most frequently overlooked requirements on a buyer’s first VA purchase, and the one most likely to surface late if it isn’t flagged early.
• New construction on a VA loan carries its own separate requirements on top of the items above, including a VA-approved builder and a builder-provided warranty. If your buyer is building rather than buying an existing home, loop in your loan officer before the builder contract is signed, not after.

USDA Loans

USDA loan requirements follow a similar pattern to VA and FHA loans but rely more heavily on the appraiser’s findings at the time of inspection.

• A water quality test is required whenever the property has a private water source.
• A septic inspection generally isn’t required unless the appraiser can’t verify distance requirements or identifies a potential issue.
• Termite inspections aren’t required at the federal level, but many states require them independently of the loan program, so confirm this is addressed even on a USDA file.

Manufactured and Modular Homes

Manufactured homes come with a separate set of requirements on top of anything tied to well or septic systems, and they apply across conventional, FHA, VA, and USDA loans:

• The home must have been built on or after June 15, 1976, and carry its HUD certification label and data plate as proof.
• It must sit on a permanent foundation and be classified and taxed as real estate, not personal property. A home that has been moved from its original site generally doesn’t qualify.
• All wheels, axles, and hitches must have been permanently removed.
• FHA and USDA loans require a licensed engineer’s certification that the foundation meets HUD’s Permanent Foundation Guide for Manufactured Housing. Conventional and VA loans require the same type of engineer certification if the home has been added onto or modified.
• Singlewide homes with a data plate manufacture date more than 10 years before the appraisal generally aren’t eligible for financing.

If you’re working with a buyer on a manufactured or modular home, this is worth flagging before the offer goes in, since missing HUD labels or an uncertified foundation can take longer to resolve than a typical inspection.

Flood Zones and Flood Insurance

A flood zone determination happens early in every file, regardless of loan type. If FEMA maps place the property in a Special Flood Hazard Area, flood insurance is required on FHA, VA, USDA, and most conventional loans before the loan can close, separate from standard homeowner’s insurance. This is worth keeping in mind in Western North Carolina. Helene exposed how many flooded properties sat outside FEMA’s mapped flood zones at the time, and flood risk in the region has drawn more scrutiny since. A property along a creek or in a river valley is worth double-checking rather than assuming its flood zone status hasn’t changed, since the added insurance cost is easier to plan for before writing the offer than after.

What Agents Can Do Early in the Process

A few habits can help you avoid last-minute surprises on any file involving a private well, septic system, manufactured home, or flood-prone property:

• Confirm early whether the property has a private well, a septic system, or both, and share that with your buyer’s loan officer as soon as it’s known, ideally before the offer is submitted.
• Ask which loan program your buyer is using, and flag it for your loan officer if it’s their first VA or USDA purchase, since these two programs carry the most property requirements.
• If a property appears to have a well and septic system in close proximity, or shows signs of an aging septic system, raise it with your loan officer before the appraisal is ordered.
• For a manufactured home, confirm the HUD data plate and certification label are present, and ask whether the foundation has already been certified.

If a property is near a creek, river, or floodplain, ask your loan officer to run the flood zone determination before the offer goes in.

• When you’re unsure whether a property will meet a specific loan program’s requirements, a conversation with your buyer’s lender before writing the offer can prevent a much longer delay later on.

Loan-Type Inspection Frequently Asked Questions

Does every private well require a water test?

On FHA, VA, and USDA loans, yes. Conventional loans typically don’t require a water test unless the appraiser raises a concern.

What happens if the well and septic system are too close together?

The buyer may need to obtain a variance from the local health department, relocate one of the systems, or in some cases negotiate repairs with the seller. Identify this as early as possible, since it can affect both timeline and cost.

Is a termite inspection always required on VA loans?

It’s required in most of the country, with a small number of exceptions in low-risk areas. Confirm with your loan officer for the specific property’s location.

Do conventional loans ever require a well or septic inspection?

Yes, if the appraiser identifies a specific concern during the appraisal. Otherwise, conventional guidelines remain the most flexible of the four loan types.

Do manufactured homes need additional inspections beyond well, septic, and termite?

They need their own foundation certification and HUD documentation, which is separate from the well, septic, and pest inspections covered above. This applies across all four loan types.

Does every property need flood insurance?

Only if it’s located in a FEMA-designated Special Flood Hazard Area. When it is, flood insurance is required on FHA, VA, USDA, and most conventional loans as a condition of closing.
