FHA vs Conventional Loans in New Hampshire: Oil Tanks, Radon and Winter Appraisals — Lilac Saltbox

Updated October 2026

An older New Hampshire house can have an attractive price and still create financing delays when the appraiser encounters a leaking oil tank, an unreliable furnace, or snow covering the septic area. Choosing FHA or conventional financing requires separating mortgage eligibility from the property's physical condition.

Compare financing without assuming conventional means unrestricted

For 2026, the FHA floor is $541,287, with higher FHA limits in Rockingham and Strafford counties. Check the property county and unit count through HUD FHA Mortgage Limits before setting the borrowing target.

The baseline conforming limit is $832,750 across eight New Hampshire counties; Rockingham and Strafford have higher limits up to $920,000. These are loan amounts, not purchase-price caps. Conventional financing may offer different mortgage-insurance options, but it does not exempt a property from basic safety, soundness, and marketability requirements.

FHA appraisals explicitly address minimum property requirements. Conventional lenders also review significant defects, and individual lender requirements can be stricter than a buyer expects. Compare financing costs separately from repair expenses using the monthly payment calculator.

Identify the conditions that can hold up closing

An oil tank is not automatically disqualifying because it is old. Visible leakage, unstable supports, damaged lines, or evidence of contamination create a different problem. Obtain a qualified assessment rather than assuming replacement alone resolves contaminated soil.

Suspected septic failureInvestigate system condition and repair feasibility

Radon testing is a buyer-protection measure, not a universal automatic FHA denial. An appraisal also does not replace a home inspection, water analysis, or septic evaluation.

Plan around winter access

Snow and frozen ground can prevent meaningful observation of roofs, grading, wells, and septic components. Ask early whether the lender needs a specialist report, repair completion, or a later inspection. Repair escrows are conditional tools, not a guaranteed workaround for an unsafe or uninhabitable property.

Review the rural septic and well guide before finalizing inspection deadlines. The Consumer Financial Protection Bureau also explains how inspections and appraisals serve different purposes.

Lilac Saltbox can help frame the financing comparison around documented condition, expected repairs, and a closing schedule that accommodates New Hampshire winter access.

Editorial Methodology & Primary Sources

Verification date: Not recorded; check the primary source and lender timestamp before relying on an estimate.

Rate comparisons use participating lender feeds, not a whole-market survey or guaranteed offers. Freddie Mac PMMS is a market benchmark, not a personalized quote. Calculator models rely on published regulatory formulas and disclosed assumptions rather than fabricated first-person loan testing.

Monthly principal and interest use the amortization formula P × r / (1 − (1 + r)−n), where r is the monthly note rate and n is the number of payments; at zero interest use P / n. PITI adds monthly property taxes and homeowners insurance; PMI is separate. APR includes applicable finance charges under Regulation Z and is not the note rate used for payments. Compare lender Loan Estimates for actual APR and fees.

The payment snapshot uses illustrative annual taxes of 1% of home price, $1,200 insurance and 0.5% PMI below 20% down, not verified local quotes. Other calculators disclose their inputs and assumptions. Published guidance and lender feeds may change independently; confirm current program rules, taxes and offers before a decision.
