Before you can build a custom home, you need land. For many buyers, that means securing a lot loan — a specialized financing product designed specifically for purchasing raw or improved land. Understanding how lot loans work, what they cost, and how they fit into your overall construction financing strategy is an important first step in the custom home building process.
What Is a Lot Loan?
A lot loan (also called a land loan) is a financing product used to purchase a parcel of land on which you intend to build a home. Unlike a construction loan, which funds the building process, a lot loan simply finances the land purchase. It's a standalone product that you'd later refinance into a construction loan when you're ready to build.
Lot loans are available for raw land (undeveloped land with no utilities or infrastructure), improved land (land with utilities, roads, and other infrastructure in place), and lots in established subdivisions or planned communities.
Why Lot Loans Are Different From Mortgages
Lenders view vacant land as a riskier investment than a home with a structure on it. Land doesn't generate income, it can be difficult to sell quickly, and its value can be more volatile than improved property. As a result, lot loans typically come with higher interest rates, larger down payment requirements, and shorter terms than conventional mortgages.
Expect lot loan interest rates to be 1–3 percentage points higher than conventional mortgage rates. Down payment requirements are typically 20–50%, depending on the type of land and the lender. Loan terms are usually 5–20 years rather than the 30-year terms available for home mortgages.
Types of Lot Loans
The type of land you're purchasing significantly affects your financing options. Improved lot loans are the easiest to obtain because the land has utilities, road access, and other infrastructure that make it more valuable and easier to sell. These loans are available from many banks, credit unions, and mortgage lenders.
Raw land loans are more difficult to obtain because undeveloped land is harder to value and sell. Fewer lenders offer raw land loans, and those that do typically require larger down payments (30–50%) and charge higher rates. If you're purchasing raw land, you may need to work with a local bank or credit union that understands the specific market.
Qualification Requirements
Qualifying for a lot loan requires a strong credit profile. Most lenders require a credit score of at least 680 for improved lots and 720 or higher for raw land. Your debt-to-income ratio, income stability, and cash reserves are evaluated similarly to other loan types. Lenders will also want to understand your plans for the land — a clear, credible plan to build a home within a reasonable timeframe makes lenders more comfortable.
Some lenders require a timeline for construction as a condition of the lot loan. If you don't begin construction within a specified period (often 1–3 years), the lender may call the loan or require refinancing.
Using Land Equity for Your Construction Loan
One of the most important advantages of owning land before you build is that your land equity can count toward the down payment on your construction loan. If you purchased a lot for $100,000 and it's now worth $120,000, you have $120,000 in equity that most construction lenders will count as your down payment contribution.
This can significantly reduce the cash you need to bring to closing when you're ready to build. In some cases, borrowers with substantial land equity can qualify for a construction loan with little or no additional cash down payment, depending on the lender's loan-to-value requirements.
Seller Financing as an Alternative
For raw land purchases, seller financing is sometimes available and can be more flexible than bank financing. In a seller-financed transaction, the land seller acts as the lender, accepting a down payment and monthly payments over an agreed-upon term. Seller financing typically requires a larger down payment (20–30%) but may offer more flexible terms and a faster closing process than bank financing.
The downside of seller financing is that the interest rate may be higher than bank rates, and the loan term is usually shorter (3–10 years), requiring you to refinance or pay off the balance when you're ready to build.
Planning Your Land Purchase
Before purchasing land, do your due diligence carefully. Verify zoning and land use regulations to confirm you can build the type of home you're planning. Investigate utility availability — connecting to water, sewer, electricity, and gas can add tens of thousands of dollars to your project cost if they're not already at the property line. Review any easements, deed restrictions, or HOA covenants that might limit your building plans. Have the land surveyed and consider an environmental assessment, particularly for rural or previously industrial properties.
