Financial planning for buy and hold

[Venky B.]

When calculating cash flow, we use 6-8% vacancy, 6-10% maintenance and 10% caps. The question I have is, if there are more than one house rented, how an invester will manage each of the accounts. If we need to look at separating out how much funds are available for each of the home, how to keep track of it. Do we need to keep separate bank accounts for each home or is there any other way of planning for keeping track of funds.

Thanks
