It's a flat roof so not a lot of space up there but enough for the racoon.I'm going to ask him his plans to repair but if he doesn't want to, what would you do? 

Your city's planning department will have a form to fill out or other method to communicate with AT&T's Engineering Department.

Anyone who is also planning to buy rentals without using any of his own money let me know we might help each other. thanks

Here are the metrics that I would use in the five categories you cite:  - Household Debt Service Payments as a Percent of Disposable Personal Income (TDSP) - Mortgage Debt Service Payments as a Percent of Disposable Personal Income (MDSP) - Consumer Loans: Other Consumer Loans: Automobile Loans, All Commercial Banks (CARACBW027SBOG) - Student Loans Owned and Securitized (SLOAS) - Consumer Loans: Credit Cards and Other Revolving Plans, All Commercial Banks (CCLACBW027SBOG)I put in links rather than images since BP tends to delete my images for some reason.

Starting a conversation up with the local Planning Department about your intended uses is a good place to start that can fill you in on the process or let you know where what you want to do might be acceptable.

Planning to look at a property in a town where I have other rentals.

I like that you have a plan and are methodically executing that plan. 

-always plan for unexpected expenses-attention to detail can emensly increase ARV.

Perhaps a family law attorney opens back up the divorce case and pursues the ex to judgment, perhaps a real estate litigator gets involved on a contingency basis or even deferred hourly if he/she can pursue treble damages for fraud, etc.… who knows.

Personally, I would never develop condos unless I plan the completely exit the building and ownership.
