Mortgage Basics: Down Payment, Interest Rates and How Much House You Can Afford

Buying a home is the biggest financial decision most people make. Understanding how mortgages work will help you borrow wisely and avoid becoming house poor.

How a mortgage works

A mortgage is a long term loan secured by the property. You repay principal and interest monthly, often over fifteen to thirty years. Early payments go mostly toward interest, while later payments reduce the balance faster.

Fixed or variable rate

A fixed rate stays the same for the term and gives predictable payments. A variable rate can start lower but changes with the market. Choose based on your budget and how much uncertainty you can handle.

Down payment and costs

A larger down payment lowers your monthly payment and may remove mortgage insurance. Also budget for closing costs, taxes, home insurance, maintenance and utilities, not just the loan payment.

How much can you afford

A common guideline is to keep housing costs under about twenty eight percent of gross income and total debt under thirty six percent. Get preapproved to know your real budget and strengthen your offer.

Tips for a better deal

Improve your credit score, reduce other debts, compare several lenders and ask about points and fees. Even a small rate difference saves a large amount over many years. Rules vary by country, so consult a licensed advisor.
