Frequently Asked Questions

What monthly budget should I plan for with a 300K loan at 5.5%?

Use $1,703 as the principal-and-interest anchor. Then include local taxes, insurance, and any HOA dues to build your all-in housing budget.

Run both scenarios side by side. A larger down payment lowers both payment and lifetime interest, while a lower rate has compounding benefits over a 30-year term.

For a 30-year repayment loan, the baseline is about $1,703 per month, with roughly $313,212 in total interest over the full term.
