Spec-home feasibility: what can you pay for the lot?
Maximum lot basis is not a mystery. It is whatever is left after a supported exit pays for the house, the site, the friction, and your profit. This calculator is that identity. It is not LotAlpha’s full underwrite, and it is not an appraisal.
Why this is only a screen
- Enter a supported exit, not a wish list. Use a sales-supported ARV or a clearly labeled directional band. Do not paste the highest asking price on the street.
- Enter costs you would defend to a partner. Hard construction, a site-work allowance, and soft costs / interest. If you do not know site work, put a wide number — do not put zero.
- Set selling cost and required profit. Commission, closing, and the profit you actually need. Shrinking profit to make the lot fit is how builders go broke on paper first.
- Read the residual lot basis. If the maximum lot basis is below asking, you negotiate or walk. This identity does not approve a loan or prove the house will sell.
