Plan from land purchase to finished home

Compare the land loan with construction financing, then estimate mortgage insurance on the completed home.

How the Land Loan Payment Is Calculated

The calculator uses the standard fixed-rate amortization formula: payment = P × r ÷ (1 − (1 + r)−n), where P is the loan amount, r is the monthly rate and n is the number of monthly payments. The loan amount is the land price minus your down payment. Cash to close adds your down payment and closing costs such as the survey, title policy, appraisal and origination fee.

Example: $150,000 of unimproved land with 25% down leaves a $112,500 loan. At 8.5% amortized over 15 years the payment is $1,107.83 a month, you pay about $86,910 in interest over the full term, and you need $40,500 at closing ($37,500 down plus $3,000 of costs).

Why Land Loans Need Bigger Down Payments

Land produces no rent and is harder to resell than a house, so lenders treat it as riskier collateral. The less developed the parcel, the more cash they usually ask for. These are typical market ranges, not rules; each lender sets its own terms.

  • Raw land (no road access, utilities or permits): often 20–50% down and 5–10 year terms, frequently with a balloon.
  • Unimproved land (some access or partial utilities): often 20–30% down and 10–20 year terms.
  • Improved lots (road, water, septic or sewer and power in place): often 15–30% down with terms that can reach 30 years.

Rates on land loans usually run above conventional mortgage rates. Local banks, credit unions and farm credit lenders are the most common sources, and seller financing is common for rural parcels.

Balloon Payments on Land Loans

Many land loans are amortized over a long period to keep the payment low but come due much sooner. When the balloon date arrives, the entire remaining balance is due at once. The calculator finds it with the remaining-balance formula Bk = P(1 + r)k − payment × ((1 + r)k − 1) ÷ r.

Example: the same 112,500 loan with a 5-year balloon still has a payment of1,107.83, but after 60 payments you owe $89,352, having paid about $43,322 in interest. Plan to sell, refinance, pay cash, or roll the balance into a construction loan before that date; the Consumer Financial Protection Bureau warns that you may not be able to refinance if rates rise or your finances change.

Before You Borrow for Land

  • Confirm zoning, setbacks and whether the lot can be built on before committing.
  • Price out a survey, a perc test for septic, well drilling and the cost of bringing in power; these often cost more than buyers expect.
  • Ask whether the lender will let you convert the land loan into a construction-to-permanent loan later. Land equity usually counts toward the construction down payment.
  • Compare the balloon balance with realistic resale value in case your plans change.

Frequently Asked Questions

Common questions about the Land Loan Calculator

Typical ranges are 20–50% for raw land, 20–30% for unimproved land and 15–30% for an improved lot with utilities. Lenders set their own requirements, and a stronger credit profile or an existing relationship with a local bank can lower the amount.
