**Condominium Mortgage Calculation**

The price of a condominium is $140,000. The bank requires a 5% down payment and one point at the time of closing. The cost of the condominium is financed with a 30-year fixed-rate mortgage at 9%. Use the following formula to determine the regular payment amount. Complete parts (a) through (c) below.

\[ \text{PMT} = \frac{P \left(\frac{r}{n}\right)}{1 - \left(1 + \frac{r}{n}\right)^{-nt}} \]

**Questions:**

a. Find the required down payment.  
$ [ \text{Box for answer} ] $

b. Find the amount of the mortgage.  
$ [ \text{Box for answer} ] $

c. How much must be paid for the one point at closing?  
$ [ \text{Box for answer} ] $

**Explanation of the Formula:**

The formula provided is used to calculate the regular payment amount (PMT) required to repay a loan. It factors in principal (P), the annual interest rate (r), the number of payments per year (n), and the total number of payments (nt).

- \( P \) is the principal, or the initial amount borrowed.
- \( r \) is the annual interest rate (in decimal form).
- \( n \) is the number of payments per year.
- \( t \) is the number of years.

This formula accounts for compound interest and is commonly used in mortgage calculations to determine monthly payment amounts.

**Problem Scenario:**

The price of a condominium is $140,000. The bank requires a 5% down payment and one point at the time of closing. The cost of the condominium is financed with a 30-year fixed-rate mortgage at 9%. Use the following formula to determine the regular payment amount. Complete parts (a) through (e) below.

**Mortgage Payment Formula:**

\[
\text{PMT} = \frac{P \left( \frac{r}{n} \right)}{1 - \left( 1 + \frac{r}{n} \right)^{-nt}}
\]

**Instructions:**

1. **Round to the nearest dollar as needed.**

2. **Part d:**
   - **Find the monthly payment (excluding escrowed taxes and insurance).**
   - Enter your answer in the space provided: $[ \hspace{3cm} ]$
   - **Round to the nearest dollar as needed.**

3. **Part e:**
   - **Find the total cost of interest over 30 years.**
   - Enter your answer in the space provided: $[ \hspace{3cm} ]$
   - **Round to the nearest dollar as needed.**

**Explanation of Formula Components:**

- \( P \) = Principal amount (loan amount)
- \( r \) = Annual interest rate (as a decimal)
- \( n \) = Number of payments per year
- \( t \) = Loan term in years
- \( \text{PMT} \) = Monthly payment amount

By substituting the given values into this formula, the monthly payment can be calculated, and subsequently, the total cost of interest over the loan period can be determined.
