Question

In the summer of 2014, the average listing price for homes for sale in the Hollywood Hills was $2,663,995.

Answer 1

Answer:

• monthly payment: $15,903.61
• interest: $2,368,664.10

Step-by-step explanation:

a) The loan amount is 90% of the price shown, so is ...

  0.90 × $2,663,995 = $2,397,595.50

The monthly loan payment is given by the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

  A = $2,397,595.50(0.0525/12)/(1 -(1 +0.0525/12)^(-12·30))

  A = $13,239.61

The monthly escrow payment will be 1/12 of the annual amount:

  0.012 × $2,663,995 / 12 = $2664.00

So, the total monthly payment on the house will be ...

  $13,239.61 +2664.00 = $15,903.61

__

b) The sum of monthly loan payments is ...

  $13,239.61 × 360 = $4,766,259.60

so the interest on the $2,397,595.50 loan is ...

  $4,766,259.60 -2,397,595.50 = $2,368,664.10
