Math Problem Statement
You and your spouse have decided it is time to purchase a home. You have a total of $10,723 that you can use for a down payment and closing costs. Since you will not be paying rent, you will have $1,070 in your budget to pay a mortgage. Your agent tells you that total closing costs will be $2,000. Your monthly escrow for taxes and insurance will be $150 in addition to your mortgage payment. You will qualify for a 30-year mortgage at 6.5%. What is the maximum you can pay for your new home?

Solution
To determine the maximum amount you can pay for a new home, we need to calculate the loan amount for which the monthly mortgage payment, excluding taxes and insurance, fits within your budget.
Here’s the step-by-step breakdown:
-
Determine the amount available for the down payment:
- You have $10,723 available, but $2,000 is required for closing costs, so the down payment is:
-
Determine the monthly mortgage payment (P&I – Principal and Interest) you can afford:
- Your total budget for housing expenses is $1,070.
- From this, $150 goes toward taxes and insurance, leaving $920 for the mortgage payment (Principal and Interest): \text{Mortgage Payment (P&I)} = 1,070 - 150 = 920
-
Use the mortgage formula to determine the maximum loan amount: The monthly payment for a mortgage can be calculated using the formula for the present value of an annuity: Where:
- is the monthly mortgage payment ($920),
- is the loan amount (which we are solving for),
- is the monthly interest rate, which is the annual interest rate divided by 12 (6.5% annual interest rate gives ),
- is the total number of monthly payments over 30 years (30 years = 360 months).
Rearranging the formula to solve for :
-
Plug in the values:
Calculating the factors: Now substitute and solve:
-
Add the down payment to find the maximum home price: Now, add the down payment of $8,723 to the loan amount:
-
Compare with the given options: The closest option to this calculated value is $154,276.95.
Answer: $154,276.95
