Every number in this thread is from January 2022, when a 30-year fixed was in the low 3s. It is not any more, so here is the current math and, more usefully, the shortcut so you can redo it yourself whenever rates move. The shortcut. At a 30-year fixed rate of about 6.65 percent, which is where Freddie Mac had the national average on August 20, 2026, principal and interest runs about $6.42 per $1,000 borrowed. Multiply your loan amount in thousands by that factor and you have the payment. Worked example on a $250,000 purchase with 5 percent down: Loan amount $237,500 Principal and interest: 237.5 x 6.42 = about $1,525 a month Then add the parts that are not the mortgage but are in the payment: Property taxes, collected monthly into escrow. Pull the actual county figure for the specific address rather than a percentage off the internet, because it varies enormously by state and by parcel. Homeowners insurance, also escrowed. Mortgage insurance, because at 5 percent down on a conventional loan you carry it until you reach 20 percent equity. On a loan this size, commonly somewhere around $80 to $150 a month depending on your credit score and the coverage required. Your loan officer can quote it exactly. HOA dues if any. Realistically, on a $250,000 house with 5 percent down, you are looking at something in the neighborhood of $1,900 to $2,200 all-in in most markets. Small-town South Dakota may land at the lower end. Get a Loan Estimate on a real property and you will see every one of those lines by name. Two things that change the answer more than anything else: Your down payment. Twenty percent down on the same house is a $200,000 loan, about $1,284 in principal and interest, and no mortgage insurance at all. Your rate. Every quarter point matters. On this loan size, a quarter point is roughly $40 a month, which is about $14,200 over thirty years. That is why it is worth getting quotes from three lenders on the same day rather than taking the first one. I am a real estate professional, not a lender, so the exact figure has to come from a loan officer running your actual credit and the actual property. I am Zoltan Peresztegi and I work in Los Angeles and the South Bay, so I am not your local agent in Brown County, but I am happy to point you toward a good South Dakota lender or agent. Zoltan
