How the estimate works
- Principal and interest use the standard fixed-rate loan formula with your price, down payment, rate and term.
- Property tax follows York County’s published method: the price × 4% (primary home) or 6%, × the 2025 millage for the area you choose.
- Mortgage insurance applies below 20% down, at the yearly rate you set (Freddie Mac’s range is about $30–$70 a month per $100,000 borrowed).
- Cash to close adds the down payment, your closing-cost percentage and a rough insurance-and-tax set-up, minus credits you have in writing.
