Run the housing numbers before you make the commitment.
Estimate the payment, test affordability, compare renting with buying, and see whether refinancing could actually save money. Then use the guides to understand the assumptions behind the result.
Use the calculator that matches the decision.
What would the monthly payment be?
Estimate principal, interest, property tax, homeowners insurance, HOA dues, and PMI from your own assumptions.
How much house can I afford?
Work backward from income, debts, down payment, taxes, insurance, and a target debt-to-income ratio to estimate a purchase budget.
Does buying beat renting over my timeline?
Compare the economic cost of renting with buying while accounting for appreciation, ownership costs, transaction costs, and the value of equity.
How long until a refinance pays for itself?
Compare the current loan with a proposed refinance, including closing costs, monthly payment savings, break-even timing, and interest over the remaining term.
Home buying guides built around the same decisions.
How Mortgage Payments Work
See how principal, interest, taxes, insurance, HOA dues, and PMI combine into the real monthly housing cost.
Debt-to-Income Ratio Explained
Understand the DTI formula, what recurring obligations may count, and why lender approval is not the same thing as a personal budget.
PMI Explained
Learn why private mortgage insurance can apply, how it affects monthly cost, and why avoiding PMI is not the only consideration.
How Much Should You Put Down?
Compare the tradeoff between a smaller loan payment and keeping more cash available after closing.
Rent vs. Buy Break-Even
See why transaction costs, ownership expenses, equity, appreciation, rent growth, and time horizon determine the break-even point.
Start with affordability
Before comparing homes, estimate a payment range that fits your income and existing monthly obligations.
Then model the payment
Use taxes, insurance, HOA dues, and PMI assumptions so the monthly number is closer to actual housing cost than principal and interest alone.
Match the tool to your timeline
Rent-vs-buy and refinance decisions depend heavily on how long you expect to stay. Short timelines can change the result even when the monthly payment looks attractive.
