Frequently Asked Questions

The 28/36 rule states that you should spend no more than 28% of your gross monthly income on housing costs and no more than 36% on total debt payments including housing.

While 20% is ideal (avoids PMI), many loans allow 3-5% down. FHA loans require as little as 3.5% down payment.

Private Mortgage Insurance (PMI) is required when your down payment is less than 20%. It typically costs 0.5-1% of the loan amount annually and protects the lender against default.
