About Home Affordability Calculator
The 28/36 rule
28% of gross monthly income goes to housing (mortgage + tax + insurance + HOA). 36% goes to ALL debt including housing. This was the underwriting standard until the 2008 crisis loosened it. Many lenders now allow up to 43-45%.
Down payment effect
Larger down payment reduces the loan and monthly P&I — letting you afford a bigger price. Down payment below 20% usually triggers PMI (extra monthly cost), reducing affordability.
What this doesn’t include
HOA dues, utilities, maintenance, repairs, and lifestyle costs. Just because you can afford the max doesn’t mean you should — leaving room for savings, emergencies, and other goals is wise.
