Answer:
$319,525.64
Step-by-step explanation:
It appears you want the interest to accumulate for 15 years before you pay anything on the loan. The value of $180,000 appreciating at 3.9% annually will be ...
$180,000·(1 +0.039)^15 = $319,525.64
If your lender allows you to wait 15 years before making any payment, your payment will be $319,525.64.

<em>Additional comment</em>
Home loans are usually paid with monthly payments computed from the formula ...
A = P(r/12)/(1 -(1 +r/12)^(-12t))
where A is the monthly payment on principal P, r is the annual interest rate, t is the number of years.
For your $180,000 loan, the monthly payment is ...
A = $180,000·(0.039/12)/(1 -(1 +0.039/12)^(-12·15)) ≈ $1322.44
The total of those payments is ...
180·$1322.44 = $238,039.20
If you pay $1322.44 monthly on the loan, your total payment is $238,039.20.
