Solution
Solution Steps
Step 1: Calculate Monthly Interest Rate
The monthly interest rate is calculated from the annual interest rate:
\[
\text{monthly interest rate} = \frac{0.035}{12} = 0.0029166667
\]
Step 2: Calculate Number of Payments
The total number of payments over the loan term of 25 years is:
\[
\text{number of payments} = 25 \times 12 = 300
\]
Step 3: Calculate Monthly Principal and Interest (PI)
Using the loan amortization formula, the monthly principal and interest payment is calculated as follows:
\[
\text{monthly PI} = \frac{280000 \times 0.0029166667}{1 - (1 + 0.0029166667)^{-300}} \approx 1401.75
\]
Step 4: Calculate Monthly Property Tax and Insurance
The monthly property tax and insurance are calculated from their annual values:
\[
\text{monthly property tax} = \frac{6573}{12} \approx 547.75
\]
\[
\text{monthly insurance} = \frac{2156}{12} \approx 179.67
\]
Step 5: Calculate Monthly PITI
The total monthly payment including principal, interest, taxes, and insurance (PITI) is:
\[
\text{monthly PITI} = 1401.75 + 547.75 + 179.67 \approx 2129.16
\]
Final Answer
The monthly principal and interest payment is approximately \( \boxed{1401.75} \) and the monthly PITI is approximately \( \boxed{2129.16} \).
