Planning estimate only. It excludes mortgage payments, tax, purchase costs, capital improvements and property-specific professional advice. A reserve is money set aside, not proof that the eventual bill will match it.
Separate routine and major works
A routine repair allowance and a separate replacement reserve make a large occasional bill less invisible.
Keep finance and tax separate
Use actual mortgage and tax figures elsewhere. This page compares property operating costs before those personal factors.
