Tracking your expenditures

[Mike Testa]

I learned some formulas on this site. Like what percentages to estimate for repairs and cap expenditures etc.   I have 1 business checking account and 1 savings account for my 4 family building.  I keep the tenants deposits in the savings account and the rest in the checking. Do you guys suggest that ?  How do you track (if you do) the separation of funds earmarked for cap expenditures, taxes , and repairs and all those separate categories?
