OFFICIAL DATA / 2026 / 1–4 UNITS

Local limits.
A clearer starting point.

Compare the standard conforming baseline, the FHFA county maximum and the FHA forward-mortgage county maximum for the actual property’s county and unit count.

As of October 30, 2026: official 2027 county limits have not appeared in the agency sources checked. Some lenders offer early 2027 conventional amounts under their own rules; these are not official FHFA or FHA limits.

San Joaquin County 2026 / 1–4 units

County limit equals the baseline, so there is no separate FHFA high-balance range for this county.

San Joaquin County: 2026 loan amount limits

1 unit$832,750$832,750$678,500
2 units$1,066,250$1,066,250$868,600

4 units$1,601,750$1,601,750$1,304,850

FHFA baseline is the standard lower-48 limit. FHA county maximum is independently set; its national floor is not a minimum loan amount. Limits are loan amounts, not purchase prices or approvals.

2026 FHA national floors: 1 unit: $541,287 · 2 units: $693,050 · 3 units: $837,700 · 4 units: $1,041,125. A floor is the lowest county maximum, not a minimum loan amount. County-specific maximums appear above.

Sources checked October 30, 2026: FHFA 2026 county table and HUD 2026 forward mortgage county file. HUD Mortgagee Letter 2025-23. FHFA values apply to loans acquired in 2026; FHA timing generally follows case-number assignment. Confirm timing, unit count, occupancy and program details with a loan officer. Approval and availability depend on the loan and property.

A CLOSER LOOK / OCTOBER 2026

Across the Altamont.
A different set of questions.

A new community, a longer commute, a different county. The right comparison begins with the specific home and the full cost of owning it.

Mountain House ↗

California’s January 2026 estimates place Mountain House among the fastest-growing cities over 30,000. Population growth is an estimate, not a count of homes for sale. Consider your actual commute and the costs attached to a particular property.

Tracy ↗

The city publishes a residential pipeline with separate categories for construction, approvals and projects under review. Check the latest report and confirm the status of a specific community before relying on a planned delivery date.

Lathrop ↗

The city identifies River Islands as an approved development under construction. Plans describe phases and a long buildout; planned homes are not the same as completed homes or current inventory.

Manteca

Compare specific neighborhoods, transportation routes and property costs. For any new home, ask about the estimated tax bill, special assessments, association dues and insurance before settling on a payment target.

Start with the whole payment.

Ask your loan officer to compare written offers using the same loan amount and assumptions. An incentive, initial payment or advertised rate is only one part of the decision. Availability and loan approval depend on the borrower, property and lender.
