Calculating your monthly payments
One of the most important factors to consider when buying a new home is affordability. As a general rule, mortgage payments should not exceed 30-40 percent of your monthly take-home pay. When calculating affordability for FHA loans you can use 45% of your monthly income for service debit that would show on your credit report and the balance would be what you can afford to pay for a monthly home payment. For example lets say you make $4,500 per month. 4500 x .45= $2,025.00 for service debit. Between your monthly payments for credit cards and car loan you pay $325 per month. $2,025.00 - $325.00 = $1,700.00 this is what you would be allowed to go up to for a home loan monthly including taxes and insurance.
Figure Out How Much You Want To Borrow
Your first step to calculating your monthly mortgage payment is knowing how much you want to borrow. This can be determined by subtracting your down payment amount from the purchase price of the home, which will give you the amount that you will need to request from a lender.
Know Your Rates
The next step is to determine the current interest rates for the purchase of a home. Rates vary and may change often, so check with your lender for current rates. It's worth noting that the interest rates you receive will, in part, be based on your credit history. This means that knowing your FICO score and credit rating will give you a good idea as to how your interest rates will be calculated.
Choose Your Loan Term
Your monthly mortgage payments will be determined by a number of factors, including the term of your loan. If you were to borrow $250,000, your monthly payments would be less with a 30-year mortgage than with a 15-year mortgage. The reason is because it would take larger monthly payments to get the loan paid off quicker, which is why you will need to select a loan term before calculating your payments.
Additional Costs To Consider
Your total mortgage payment will include taxes, homeowner's insurance and possibly even private mortgage insurance (PMI) if you provide less than 20 percent down and your loan requires it.
