Raw land loans cost more than residential mortgages. 80,000 land at 7.5% over 15 years = around 556/month. Typical requirements: 30-50% down, rates 1-3% higher than home mortgages, shorter terms. Lenders see land as riskier because there's no structure to repossess usefully.

A worked example

Try the defaults: land price of 80,000, down payment of 20,000, annual rate of 7.5%, term of 15. The tool returns 556.21. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to Land Price, Down Payment, Annual Rate, and Term. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

The formula behind this

Standard amortisation formula applied to the loan balance after deposit. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.

Stress-testing the plan

Run the calculation at your current rate, then run it again at a rate 2–3 percentage points higher. That's roughly what a product reset could bring at renewal, and it's a useful check on whether you can afford the mortgage in a higher-rate world, not just today's.

What this doesn't capture

The figure excludes arrangement fees, valuation costs, legal fees, insurance, and any early-repayment charges — those can add several thousand to the headline cost. Rate changes at renewal for fixed-term deals will shift the picture further. Use this for the core interest/principal math and add the other costs on top.

Frequently Asked Questions

Why are land loans more expensive?
Higher lender risk — no house to secure against. Foreclosure on raw land is harder to monetise. Rates reflect this premium.
Can the loan convert when building?
Some land-to-construction loans convert automatically. Otherwise you refinance into a construction loan and then into a mortgage once finished.
Raw vs improved land?
Improved land (utilities, road access) gets better rates and terms. Raw land has steepest requirements and highest rates.
Larger deposit helps?
Materially. 50%+ down often unlocks standard mortgage rates on improved residential plots. Below 30% may mean specialised lenders only.
