These calculators give you a reliable ballpark based on what you enter. They are built to help you understand the range of numbers involved — not to replace a formal Loan Estimate. For a precise quote, a Flagstone loan officer can provide a full Loan Estimate within 24 hours.

Use current average 30-year fixed rates as your starting point. Your actual rate depends on your credit score, loan type, down payment, and property. Flagstone offers free rate quotes in about five minutes and it does not affect your credit score.

Start with the Home Affordability Calculator to establish a price range, then use the Monthly Payment Calculator to confirm the monthly number fits your budget. The Closing Cost Calculator is also critical — most first-time buyers are surprised by how much cash is needed at closing beyond the down payment.

Run the Net Proceeds Calculator first to understand how much equity you will have from the sale. Then use the Affordability or Monthly Payment Calculator to plan your next purchase using that equity as a down payment. A Flagstone loan officer can help you time both transactions to avoid holding two mortgages simultaneously.

A 2-1 buydown is a seller-funded arrangement that temporarily lowers your interest rate by 2% in year one and 1% in year two. Use the Temporary Buydown Calculator to see the exact payment difference and whether the upfront cost makes sense for your deal.
