This depends on several factors, including your income, debt, and down payment. A good rule of thumb is that your total monthly housing expenses should not exceed 28% of your gross monthly income. You can use a mortgage calculator to get a more accurate estimate of how much you can afford to borrow.

A fixed-rate mortgage has an interest rate that remains the same throughout the life of the loan. An ARM has an interest rate that can fluctuate over time, based on a market index. ARMs typically have lower initial interest rates than fixed-rate mortgages, but the rate can increase over time, making your monthly payments higher.

The best type of mortgage for you will depend on your individual circumstances. If you are looking for predictability and stability, a fixed-rate mortgage may be a good option. If you are comfortable with the possibility of your interest rate increasing in the future, an ARM may save you money in the short term.

While a 20% down payment is ideal, it is not always required. Many lenders offer conventional mortgages with down payments as low as 3%. If you put down less than 20%, you will likely be required to pay private mortgage insurance (PMI) until you reach 20% equity in your home.

PMI is an insurance policy that protects the lender in case you default on your mortgage. You are typically required to pay PMI if you put down less than 20% on your home. PMI can add hundreds of dollars to your monthly mortgage payment.

The steps to getting a mortgage can vary depending on the lender and the type of loan you are applying for. However, in general, the process will involve:
Getting prequalified

Shopping around for a mortgage lender

Putting in an offer on a home

Applying for a mortgage

Closing on the loan

Closing costs are fees that you pay in addition to the purchase price of the home. These costs can include things like origination fees, appraisal fees, and title insurance. Closing costs typically range from 2% to 5% of the purchase price of the home.
