Every worksheet here gives estimates for planning, not an approval, an appraisal, or a legal opinion. Values, rents, rehab scopes, tax rules, and loan terms all move once you are in a real deal, so confirm the numbers with your lender, contractor, attorney, and accountant. Nothing on this page is tax, legal, or investment advice.
