Top 5 Things to Know About USDA Rural Development Mortgage Appraisals

USDA appraisals look a lot like FHA appraisals — until they don't. If you're buying in Maine with a Rural Development loan, the appraisal is where most deals either lock in or fall apart. Here's what actually matters, written by a Maine loan officer who closes these every month.

1. A USDA appraisal is a valuation and a property condition review

On a conventional loan, the appraiser's job is narrow: confirm the home is worth what you're paying for it. On a USDA Rural Development loan, the appraiser has a second job layered on top — confirm the property meets USDA's Minimum Property Requirements (MPRs), which USDA has largely aligned with HUD Handbook 4000.1 (the FHA standard).

That means a single USDA appraisal is essentially doing two things at once: setting the value, and flagging anything about the home's condition that violates habitability, safety, soundness, or security standards. It is not a substitute for a private home inspection — your inspector is looking for things the appraiser isn't paid to find (minor mechanical issues, cosmetic defects, future-maintenance items). But it is more scrutiny than a conventional appraisal, and that matters.

How USDA appraisals differ from FHA and conventional

2. Wells, septic systems, and water tests — the Maine reality

This is where Maine USDA deals most often run into friction. Outside of a handful of downtowns, the majority of Maine properties that qualify for USDA are on private wells and private septic — and USDA has specific rules about both.

Private well water testing

If the home's water comes from a private well, USDA requires a water test performed by a state-certified laboratory. At a minimum, the sample must be tested for:

• Coliform bacteria (total coliform and E. coli)
• Nitrates (max 10 mg/L)
• Nitrites (max 1 mg/L)
• Lead (max 15 µg/L)

In Maine specifically, given the region's geology, most lenders (including LeaderOne) also require testing for arsenic and uranium. Both are common in Maine groundwater, particularly in parts of York, Cumberland, Oxford, Kennebec, and Hancock counties. Arsenic above 10 µg/L or uranium above 30 µg/L will require a treatment system be installed and certified before closing.

Septic systems

USDA does not automatically require a septic inspection, but the appraiser must comment on the functional adequacy of the system. If there is any visible sign of failure — standing water, foul odor, sagging ground over the leach field, slow drains reported by the seller — an inspection by a licensed Maine Site Evaluator is required, and any deficiencies become required repairs.

If the home is served by a cesspool (common on older Maine camps and some year-round homes built before 1970), USDA will typically require replacement with a conforming septic system before closing, unless local jurisdiction allows continued use. This is one of the most common reasons older Maine properties don't make it to a USDA closing.

Shared wells and springs

Shared wells are allowed if a recorded, legally enforceable well-sharing agreement exists. Springs and cisterns are generally not acceptable as the sole water source. Seasonal-use systems (dug wells that freeze, for example) will be flagged.

3. Required repairs: what actually must be fixed before closing

The USDA appraiser will note items in one of three buckets:

1. Subject to repairs completed — must be fixed before the loan can close.
2. Subject to inspection — a specialist (roofer, electrician, septic, well, pest) must inspect and certify the item, then any findings are treated like bucket #1.
3. As-is — the home passes USDA's MPRs and no conditions are required.

When an appraiser writes the report "subject to repairs," those repairs have to be completed, inspected, and signed off on by the appraiser (a re-inspection, typically $150 to $200) before the file clears to close. Here is what triggers it most often on Maine properties:

Who pays for repairs?

Technically, anyone can pay — seller, buyer, a third party. In practice, most purchase contracts are negotiated so the seller either performs the work or provides a closing-cost credit that the borrower uses to complete it after closing. But USDA does not allow "escrow holdbacks" for exterior repairs weather-dependent in Maine winters the same way FHA 203(k) does — it's tighter. If the work cannot be completed before closing, talk to your loan officer early about whether a USDA escrow holdback is possible (it's allowed in limited circumstances for weather-delayed exterior work, but it requires lender and USDA approval).

4. How long the appraisal is good for

A USDA Rural Development appraisal is valid for 150 days from the effective date of the report (180 days for new construction). That's 30 days longer than FHA and meaningfully longer than many conventional lender requirements — helpful in Maine, where closings that touch well testing, septic inspection, and wintertime repair work can drag.

If you need more time, the appraisal can usually be extended an additional 30 days with a recertification of value — a brief update from the original appraiser confirming market conditions haven't materially changed. This is not an automatic extension; it requires the original appraiser and a new fee (typically $100 to $150).

Appraisals transfer between lenders

If you start with one lender and switch mid-process, USDA requires the first lender to transfer the appraisal to the new lender at the borrower's request. Some lenders drag their feet on this — you have the right to insist. The appraisal doesn't have to be re-ordered just because your loan moved.

5. "Modest housing" — and what USDA will not finance

USDA is explicit that Rural Development loans are for modest housing: a primary residence that is reasonable, typical, and adequate for the area — not a luxury home. In practice, this rules out or complicates several property types Mainers commonly look at:

• Working farms. USDA RD will not finance a property whose primary use is agricultural production. A home on 10 rural acres with a hobby garden is fine; a home on 60 acres with an active hay operation and equipment sheds is not.
• Income-producing outbuildings. A detached barn the seller rents out to store boats, or a building used as a commercial workshop, cannot be included in the appraised value and may disqualify the property entirely.
• In-ground swimming pools. An in-ground pool's contributory value is excluded from the USDA-appraised value. The pool itself doesn't disqualify the home, but the value you can borrow against won't include it.
• Secondary living units that function as rentals. Accessory dwelling units (ADUs) are allowed only if the property still meets USDA's single-family-residence standard and the ADU isn't separately rented as a business.
• Unique or atypical properties. If the appraiser can't find 3 comparable sales within a reasonable distance and time period, the property may be deemed "not modest" or "not supported by market data." Remote parts of Aroostook, Washington, and Piscataquis counties see this occasionally — comps may need to come from 5+ miles away and go back 12 months.
• Manufactured homes on leased land. Not eligible. The land must be titled to the borrower.

None of this means rural Maine is off the table — it's the opposite. Most of Maine is USDA-eligible and most homes qualify comfortably. But the "modest" standard is a real filter, and it catches a handful of buyers every year who didn't know the rule going in.

The typical Maine USDA appraisal timeline

The biggest variable is the repair list. A clean "as-is" appraisal keeps a 30-day close on track. Anything subject-to adds 5 to 14 days, depending on the trade needed and the seller's cooperation.

Frequently asked questions

How much does a USDA appraisal cost in Maine?

Most Maine USDA appraisals run $550 to $750, paid upfront by the borrower when the report is ordered. Rural and remote properties (Aroostook, Washington, Piscataquis) sometimes carry a premium of $100–$200 for driving distance. Well water tests are separate — typically $150 to $300 depending on the panel of contaminants tested.

Do I need a home inspection if USDA is already appraising the property?

Yes — get a private home inspection anyway. The USDA appraiser is confirming the home meets minimum property requirements. A good home inspector is there to protect you: they'll find issues the appraiser isn't obligated to flag (aging HVAC, minor plumbing leaks, electrical nits) and give you leverage in negotiations. Two different jobs.

What if the appraisal comes in below the purchase price?

Three options: seller drops the price to the appraised value; buyer brings extra cash to cover the gap (USDA allows this, but it reduces the 100% financing benefit); or the purchase contract is renegotiated or canceled using an appraisal contingency. USDA does not allow the loan amount to exceed 100% of the appraised value (plus the 1% upfront fee, which can be financed), so a low appraisal has to be addressed — it can't be ignored.

Can I challenge a USDA appraisal?

Yes. If you or your agent believe the value is wrong, you can submit a Reconsideration of Value (ROV) through the lender. It needs to include 3 to 5 recent comparable sales the original appraiser missed, with clear reasoning. ROVs succeed maybe 20–30% of the time. If the value is still wrong after the ROV, the only remaining option is to order a second appraisal — and USDA is strict about when a second appraisal is allowed to replace the first.

Does USDA require flood insurance?

Only if the property is in a FEMA Special Flood Hazard Area (SFHA). The appraiser will pull the flood zone determination and note it. If the home is in an SFHA, flood insurance is required for the life of the loan. In coastal Maine — parts of York, Cumberland, Hancock, Knox, and Washington — this comes up regularly.

Does USDA require termite or pest inspection in Maine?

Maine is considered a "moderate to heavy" termite infestation area by HUD standards, so southern Maine USDA loans frequently see a termite inspection requirement. If the appraiser notes evidence of wood-destroying insects (carpenter ants are extremely common here), a treatment and clearance letter from a licensed pest company will be required.

What happens if the appraisal expires before we close?

Request a recertification of value from the original appraiser (≈30 days extra, $100–$150). If more than 180 days have passed, a new appraisal is required. This is uncommon on a well-managed file but does happen when major repairs or title issues delay closing.

Can the appraiser's required repairs be done after closing?

Almost always no — USDA requires required repairs to be completed before closing. The narrow exception is an escrow holdback for weather-delayed exterior work (roofing, exterior paint, grading) between roughly November and April in Maine. This requires lender and USDA approval, a signed repair contract, and typically 150% of the repair cost held in escrow. Ask early; don't assume it will be available.

Who selects the USDA appraiser?

Neither you nor your lender picks the appraiser directly. Federal rules require appraisals be ordered through an independent Appraisal Management Company (AMC) that rotates assignments among USDA-approved appraisers in the market. This is designed to prevent pressure on the appraiser to "hit the number." Your lender does choose which AMC to use.
