Can I Get a Mortgage on 5, 10 or 20+ Acres? Mortgage vs Land Loan

Buyers across Bulverde, Spring Branch and Canyon Lake ask the same question: can my mortgage cover the whole place, or do I need a separate land loan? The answer depends on one thing, whether a habitable home is part of the deal. This page walks the verified agency rules so you know which product fits before you call a lender.

Home loans vs land loans: the line in the sand

A home loan finances a home. The land is part of the security, but the property has to work as a residence, with the home and site appraised together. That is why Fannie Mae, USDA and VA each have acreage rules, because a 40-acre tract with a house is still a home loan, while 40 acres with no house is not.

A land loan (or lot loan) finances land only, for building later or holding as an investment. Land loans fall outside the home-loan rules on this page, have their own rates, down payments and terms, and those terms were not verified in this pass. I will not quote you a land-loan rate, because the honest answer is to check lenders directly, for example Texas Farm Credit, for current terms on the exact tract.

Fannie Mae: the appraisal must cover the whole site

Fannie Mae Selling Guide B4-1.3-04 (06/04/2025) is direct: the appraisal must address the entire site, and the appraiser may not appraise only 5 acres of an unsubdivided 40-acre parcel. If you are buying 12 acres, the appraisal covers all 12, and the land has to be supportable as part of the value.

Not verified: any Fannie Mae excess-land or acreage cap. We did not confirm a published cap in this pass. If a lender or agent quotes you one, ask for the Selling Guide section, or check the Fannie Mae Selling Guide directly.

USDA: no acreage cap, but the land cannot pay the mortgage

USDA Rural Development site requirements (7 CFR 3555.201, rule effective Mar 9, 2016) set no maximum acreage limitation, so a USDA loan can cover a large rural tract in Comal or Guadalupe County. The catch is the site must not be income producing. A small garden is allowed, but land that generates farm income, or a commercial setup, will not pass the site review.

The related USDA income limits are a separate yearly check, and the honest method for those is the official USDA tool, which I detail on the USDA income limits page.

VA: no acreage limit, with the rural property rules on top

VA Pamphlet 26-7 Chapter 12 (revised Oct 18, 2019) does not set a limit on the number of acres. VA financing can cover a home on substantial acreage, as long as the property appraises at or above the price and the land is reasonable relative to the improvements. VA's rural rules on wells, septic and private roads apply, and I break those down on the VA loans on rural property page.

When you need a land loan instead

• Raw land with no current home. Fannie Mae, USDA and VA all finance homes, not vacant land under these rules.
• Land you plan to build on later. A land loan carries the ground, and the construction financing (for example a construction-to-permanent loan) is a separate step.
• Splitting or holding acreage. If the plan is a future subdivision or an investment hold, that is a land lender's product.

Land-loan rates, down payments and terms were not verified in this pass, so check lenders directly, such as Texas Farm Credit, for the current numbers on the exact tract.

What to verify on the specific property

• Subdivided or unsubdivided parcel. Fannie Mae's whole-site rule changes how the appraisal works on an unsubdivided 40-acre parcel, so confirm the parcel status with the survey and the appraisal district.
• Income-producing use. USDA rules prohibit it; confirm the current use and any ag or wildlife valuation on the Comal CAD record.
• Well, septic and access. These carry their own rules on rural acreage, detailed for VA on the VA rural property page.
• FHA acreage rules. Not verified in this pass. HUD Handbook 4000.1 governs FHA, and the honest check is the handbook itself at hud.gov.
