New Mexico FHA Loan Requirements 2026
Thirty-one of New Mexico’s thirty-three counties share the same FHA loan limit. Los Alamos and Santa Fe sit above it. This guide covers the 2026 limits county by county, credit and down payment requirements, how mortgage insurance works, and how FHA stacks with Housing New Mexico assistance.
New Mexico FHA Loan Limits by County
Thirty-one of New Mexico’s thirty-three counties sit at the 2026 national FHA floor. Two clear the high-cost threshold and carry higher limits.
| Area | One family | Two family | Three family | Four family |
|---|---|---|---|---|
| 31 counties at the floor | $541,287 | $693,050 | $837,700 | $1,041,125 |
| Los Alamos County | $692,300 | $886,250 | $1,071,300 | $1,331,350 |
| Santa Fe County | $569,250 | $728,750 | $880,900 | $1,094,700 |
FHA high-cost limits are calculated at 115% of the local median sale price. HUD used a $600,000 median for Los Alamos and $495,000 for Santa Fe. Verified against the HUD FHA Mortgage Limits lookup for CY2026, which returns 33 records for New Mexico.
FHA Requirements in New Mexico
FHA requirements are federal and identical everywhere. What varies in New Mexico is only the limit, and only in two counties.
| Requirement | FHA Standard | Notes |
|---|---|---|
| Minimum down payment | 3.5% | At 580 or above; 10% between 500 and 579 |
| Occupancy | Primary residence | No investment properties or second homes |
| Loan limit | $541,287 in 31 counties | $692,300 in Los Alamos, $569,250 in Santa Fe |
| Appraisal | FHA appraisal required | Property must meet HUD minimum property standards |
| Mortgage insurance | Required | Upfront and annual — see below |
FHA Mortgage Insurance Premiums (MIP)
FHA charges mortgage insurance twice: once upfront and again annually for the life of most loans.
| Premium | Rate | Applies to |
|---|---|---|
| Upfront MIP | 1.75% of base loan amount | All purchases and refinances |
| Annual MIP, LTV over 95% | 55 basis points | The standard 3.5% down purchase |
| Annual MIP, LTV 90.01% to 95% | 50 basis points | Loans with 5% to 10% down |
| Annual MIP, LTV 90% or less | 50 basis points | Loans with 10% or more down |
Every New Mexico FHA loan falls in the “$726,200 or less” premium tier — including Los Alamos, whose $692,300 limit still sits below that threshold. So the higher county limits do not push any New Mexico borrower into the higher premium band.

FHA Versus Conventional in New Mexico
With a $248,100 median home value, most New Mexico buyers choose between these on credit and mortgage insurance rather than on loan size.
| Factor | FHA | Conventional |
|---|---|---|
| Minimum down payment | 3.5% | 3% |
| Mortgage insurance | 1.75% upfront + 55 bps annual | PMI, no upfront premium |
| Can insurance be cancelled? | No, for most loans | Yes, at 80% LTV |
| 2026 limit | $541,287 in 31 counties | $832,750 in all 33 |
| Credit flexibility | More forgiving | Stricter tiers, priced by score |
Conventional carries the higher limit in every New Mexico county. The cancellation difference usually decides it: FHA insurance stays for the life of most loans while conventional PMI drops at 80% LTV.
Housing New Mexico Assistance + FHA
FHA financing and Housing New Mexico assistance are designed to stack, and FHA is named explicitly as an eligible first mortgage.
| Program | Pairs with FHA? | What it adds |
|---|---|---|
| FirstDown | Yes — FHA named explicitly | Up to 4% of the sales price |
| HomeNow | Via FirstHome | $7,000, forgivable after 10 years |
| FirstDown Plus | Via FirstHome | $10,000 at 0% over 15 years |
| Manufactured Home Financing | Yes — FHA named explicitly | Assistance for manufactured homes |
FirstDown’s own fact sheet lists FHA, VA, USDA, HUD Section 184, HFA Advantage and HFA Preferred Conventional as eligible first mortgages. FirstDown or HomeNow plus FirstDown Plus stops at $35,000 combined.
