1. **State the problem:** You can afford monthly payments of 600. The mortgage rate is 2.41% annually for a 15-year fixed loan. We want to find how much you can borrow (the loan principal $P$).
2. **Formula used:** The loan payment formula is
$$M = P \times \frac{r(1+r)^n}{(1+r)^n - 1}$$
where:
- $M$ is the monthly payment,
- $P$ is the loan principal (amount borrowed),
- $r$ is the monthly interest rate (annual rate divided by 12),
- $n$ is the total number of payments (months).
3. **Calculate parameters:**
- Annual interest rate = 2.41% = 0.0241
- Monthly interest rate $r = \frac{0.0241}{12} = 0.002008333...$
- Loan term = 15 years = $15 \times 12 = 180$ months
4. **Rearrange formula to solve for $P$:**
$$P = M \times \frac{(1+r)^n - 1}{r(1+r)^n}$$
5. **Calculate $(1+r)^n$:**
$$ (1+0.002008333)^{180} = 1.002008333^{180} \approx 1.4116 $$
6. **Substitute values:**
$$P = 600 \times \frac{1.4116 - 1}{0.002008333 \times 1.4116} = 600 \times \frac{0.4116}{0.002835}$$
7. **Simplify:**
$$P = 600 \times 145.13 = 87078$$
So, you can afford to borrow approximately **87078**.
8. **Calculate the maximum home price with 20% down payment:**
If $P$ is 80% of the home price $H$, then
$$H = \frac{P}{0.8} = \frac{87078}{0.8} = 108848$$
**Final answers:**
- Amount you can borrow: **87078**
- Maximum home price you can afford: **108848**
