How much house can I afford?

Use the 28/36 rule: housing costs should not exceed 28% of gross monthly income, and total debt should not exceed 36%.

What's the difference between APR and interest rate?

Interest rate is the cost of borrowing the principal. APR includes the interest rate plus fees and closing costs, showing the true annual cost.

Should I put down more than 20%?

Putting down 20% avoids PMI. More than 20% reduces your loan amount and monthly payment but ties up more capital.
