Putting down 20 percent or more avoids private mortgage insurance (PMI) on conventional loans, which saves money monthly.
A 15-year mortgage typically offers a lower interest rate than a 30-year mortgage, saving tens of thousands in total interest.
Budget for property taxes and homeowners insurance on top of your principal and interest payment since these are part of total housing cost.
Even small extra payments toward principal early in the loan term have a large impact on total interest due to compound savings.
Shop around and get quotes from at least three lenders since rates and fees can vary significantly between institutions.
How much house can I afford?
A common guideline is to keep your total monthly housing payment below 28 percent of your gross monthly income. This includes principal, interest, taxes, and insurance combined. Your total debt payments should generally stay under 36 percent of gross income.
What is PMI and when do I pay it?
Private mortgage insurance is required on conventional loans when your down payment is less than 20 percent. It protects the lender if you default. PMI typically costs between 0.5 and 1 percent of the loan amount per year and can be removed once you reach 20 percent equity.
Should I choose a fixed or adjustable rate?
Fixed-rate mortgages lock in the same rate for the entire term, giving predictable payments. Adjustable-rate mortgages start lower but can increase over time. Fixed rates are generally safer for long-term homeowners who plan to stay in the property.
What is included in a monthly mortgage payment?
A standard mortgage payment includes principal, interest, property taxes, and homeowners insurance, often abbreviated as PITI. If your down payment is below 20 percent, PMI is added as a fifth component.
How does a larger down payment affect my mortgage?
A larger down payment reduces the loan amount, which lowers both the monthly payment and total interest paid. It may also eliminate PMI requirements and can help you qualify for a better interest rate from lenders.
