This is a quick estimate of principal and interest only. It doesn't include property tax, homeowners insurance, HOA dues, or private mortgage insurance (PMI), which typically applies to down payments under 20% and would add to the lower-down-payment scenario's real monthly cost beyond what's shown here.
