All-In Monthly Cost at $550,000 Purchase Price
To make the comparison meaningful, every community uses the same $550,000 purchase price and the same financing assumption: 20% down ($440,000 financed at 6.75%, 30-year fixed). The only variable that changes the real monthly cost is the county — which sets the property tax rate.

HOA Fees Are a Secondary Variable
