Most buyers researching a custom home focus on construction cost first and financing second — but if you don't already own a homesite, the land loan is usually the first financing decision you'll actually make, and it works nothing like a standard home mortgage. Here's what buyers in Milton, Alpharetta, and the broader North Atlanta market should understand before they apply.
Why Land Loans Work Differently Than a Home Mortgage
A conventional mortgage is secured by a finished, appraisable structure that a lender can resell relatively easily if a loan defaults. Vacant land carries none of that built-in liquidity — there's no structure, no rental income, and a smaller pool of buyers if the lender ever has to foreclose and resell. That extra risk is why land loans typically come with higher down payment requirements, higher interest rates, and shorter terms than a typical 30-year mortgage.
Raw Land vs. Improved Land: The Distinction That Drives Your Rate
Lenders generally split land into two categories, and the difference matters more than buyers expect. Raw land has no utilities, roads, or grading — essentially untouched. Improved (or unimproved-but-serviced) land already has some combination of road access, utility availability, and survey work completed. Raw land is considered the higher-risk category and commonly requires a larger down payment — often 20–50% depending on the lender — while land that's closer to build-ready can sometimes qualify for more favorable terms closer to a standard construction loan.
What Lenders Actually Look At
Beyond your credit and income, a land loan underwriter is evaluating the site itself: zoning and permitted use, access to utilities or the cost to bring them in, topography and drainage, and whether you have a concrete plan to build within a defined timeframe rather than holding the land indefinitely. A lender is far more comfortable financing land with a real construction plan attached than land being purchased speculatively, which is part of why having preliminary site evaluation done — the same due diligence covered in our free North Atlanta Development Guide — strengthens a loan application, not just a purchase decision.
Typical Terms You Should Expect
Land loan terms vary by lender and by how developed the parcel already is, but a few patterns hold fairly consistently in this market: shorter loan terms, often 2–5 years rather than 15–30; higher interest rates than a comparable home mortgage, reflecting the added risk; and a larger required down payment than most buyers expect coming from a traditional home-buying background. None of this is a reason to avoid buying land — it's simply a different financial structure that's worth budgeting for from the start rather than discovering midway through a purchase.
Construction-to-Permanent Loans: The Other Path
Many buyers building a custom home skip a standalone land loan entirely and instead use a construction-to-permanent loan, which finances the land purchase and the construction cost together in a single loan that converts to a standard mortgage once the home is complete. This can simplify closing costs and paperwork, but it generally requires having your builder, plans, and budget largely finalized before the loan closes — which is part of why lining up land and a builder relationship early, rather than sequentially, tends to produce a smoother financing process.
Budgeting Beyond the Loan Itself
The loan is only part of the real cost of acquiring and carrying land before construction begins. Property taxes, any HOA or association dues, liability insurance on vacant land, and interest carrying costs during the entitlement and design phase all add up before a foundation is poured. Our guide to what custom homes actually cost in this market walks through the construction side in more detail, and financing and carrying costs specifically are covered in the free North Atlanta Development Guide available on our Resources page.
If You're Evaluating Land to Build On
Financing is only one part of deciding whether a specific parcel makes sense. If you're comparing land in Milton, Alpharetta, Roswell, Johns Creek, or Duluth, our guide to choosing the right homesite covers what to evaluate on the site itself. And if you already own land and are weighing whether to build or sell, our companion piece on selling land to a developer lays out that side of the decision. Either way, reach out directly and we can talk through what's realistic for your specific site and timeline.
