Time value of money question - PV

Ms. Clara Johnson is buying a house. She expects her budget to allow a monthly payment of $1500 on a 25-year mortgage with an annual interest rate of 6.8 percent. If Johnson makes a 10 percent down payment, the most she can pay for the house is closest to:

A) $216,116. B) $240,129. C) $264,706.

The way the professor solved this:

 B is correct. The consumer’s budget will support a monthly payment of 1,500.

Given a 25 year mortgage at 6.8percent, the loan amount will be $216,115.8.This is obtained by entering the following values :

N = 300,I= 6.8/12,PMT = 1,500,CPT PV.If she makes a 10% down payment –> 240,129.

Anyone else notice something wrong with the math?

I think the math is fine. Can you explain how it is wrong?

I agree that the loan amount is 216,115. 

If she pays 10% of that (21,611) then we get a total amount of 237,726.

How do we reach 240,129?

Let P represent the price of the house

P = 0.1 x P + loan

0.9 x P = loan

0.9 x P = 216,116

P = 216,116 / 0.9

P = 240,129

Therefore, the maximum Clara can pay is $240,129.

She’s not paying 10% of the loan amount as a down payment; she’s paying 10% of the price as a down payment.

Simplify the complicated side; don't complify the simplicated side.
