Yearly = value*1% + age*0.02%*value + condition adjust; Monthly = yearly/12

How does this work?

1% rule: yearly maintenance ~1% of value, plus older homes add ~0.02% per year of age. Poor condition adds 30%, good subtracts 20%.

This covers HVAC, roof, plumbing, paint. Major systems (roof $10k, HVAC $8k) average over 10-20 years.

For YMYL budgeting, save 1-3% yearly in maintenance fund, not just mortgage.
