Cash reserves/ unit/ house

[John G.]

I'm just trying to get an idea of what everyone likes to have for cash reserves for cap ex, maint., etc.  I am up to 22 units which all of a sudden there I am.  Its easy to lose track of how much one SHOULD have in the bank because its hard to leave money sitting and not working for you.

I understand there are many variables such as age of house, age of roof, age of furnace, etc.  But, I'm just curious what everyone else likes to have sitting there waiting per unit or per house.
