Can you please help me with this question

Suppose you can get a loan with a below-market interest rate from a home builder. The fully amortizing FRM loan has 4% interest rate, 30 year amortization, $240,000 loan amount. If the home usually sells for $300,000, at what price should the homebuilder sell the home to you in order to earn a market return of 4.5% on the loan? Assume you will hold the loan for 30 years.
