Do you want to get to x number of doors so you can retire or are you looking to park some excess cash in an asset you can control? 

Any expenses in excess of your rental income from related parties is not deductible. 

I am sure  there is excessive wear and tear.

As Elijah said, if the deals aren't cash flowing in excess of the preferred return on day 1, don't distribute monthly.

So let's say there is some moisture on the wall, his tenant calls him, my tenant calls me. 

So we pay title company > title company pays loan, and if there is any excess, this goes to the seller/original borrower.Assumptions, while they still happen, are much more rare in my experience. 

But the truth is I budget conservatively and would rather have excess reserves than be scrambling to come with cash when expenses come up.

Even though they are paying for the utilities, it is putting excessive wear on the system and I worry it will fail prematurely, which would be my cost to bear.Does such a product exist?

I like deals that generate 2k or a more, a Month, in excess cash flow after all debt seduce and expenses are paid for.
