A couple wants to lend money using the house value as a cover. The lender will lend them 70% of the value of the house. The couple bought the house 12 years ago for $ 79,000. The house is financed by a deposit of 20% and a mortgage loan at 30 years and 12% interest on the unpaid amount of debt. Equal monthly repayments will be amortized over a 30-year period. The net worth of the house now is $ 100,000. After the 144th monthly repayment, the couple asks the lender for the maximum amount of the loan. How much money (up to the nearest dollar) will the couple get?
To calculate the maximum loan amount that the couple can get, we need to follow these steps:
Step 1: Calculate the remaining mortgage loan balance
The couple bought the house 12 years ago with a mortgage loan. We need to calculate the remaining balance on the loan after 144 monthly payments.
To calculate the remaining balance, we can use the formula for a fixed-rate mortgage:
Remaining balance = Loan amount * [1 - (1 + interest rate) ^ (-number of months)] / interest rate
Loan amount = House value - Deposit amount
Interest rate = 12% per year / 12 (since it's compounded monthly)
Number of months = 30 years * 12 months per year - 144 payments already made
Using these values, we can plug them into the formula and find the remaining balance on the mortgage loan.
Step 2: Calculate the maximum loan amount based on the house value
The lender agrees to lend 70% of the value of the house. We can use this percentage to calculate the maximum loan amount.
Maximum loan amount = House value * 70%
Step 3: Compare the remaining balance with the maximum loan amount
Finally, we compare the remaining balance on the mortgage loan with the maximum loan amount. The couple will get the lower amount of the two.
Let's calculate each step step by step:
Step 1:
Loan amount = $79,000 - 20% ($79,000) = $79,000 - $15,800 = $63,200
Interest rate = 12% per year / 12 = 1% per month
Number of months = 30 years * 12 months per year - 144 payments already made = 30 * 12 - 144 = 216 months
Remaining balance = $63,200 * [1 - (1 + 0.01) ^ (-216)] / 0.01
Step 2:
Maximum loan amount = $100,000 * 70% = $100,000 * 0.7
Step 3:
The couple will receive the lower amount between the remaining balance and the maximum loan amount.
To get the final answer, let's calculate the remaining balance and compare it with the maximum loan amount using the given numbers:
Remaining balance ≈ $34,274.93
Maximum loan amount ≈ $70,000
Therefore, the couple will be able to borrow up to $34,274 (rounded to the nearest dollar) from the lender.
