Cash management (zero balance, aggregation etc)

[Yuriy Shepelin]

Hi all. I understand that a typical strategy for an apartment complex is to do one LLC per building, and a separate bank account for each LLC (and so a separate bank account per property). I worked in a treasury department for a fortune 100 company and while I didn't touch cash, there were bunch of standard practices, such as the ability to segregate income and disbursements, have lockbox services, accumulation and zero balance accounts that should reduce the amount of slush capital you have to keep especially as you add properties. Has anyone setup anything more elaborate that is working well for multiple multi-family properties? How are you managing the accounting and which banks offer these services for someone with fairly minimal needs compared to a fortune 100 company? Thanks.
