It starts with educating yourself and becoming an expert.

I have been communicating with the tenant via text message, and certified mail because he would not provide an email.

The experts on mult-family are commercial appraisers and they wont even talk to you.

I am not saying you are planning that, but make sure you have a CPA doing your taxes so they can certify it is all above board. 

Some of the so-called experts also say that if the dam stops generating power (which it is contractually obligated to do at some water level, and we're not even close to that level), the river flow will quickly increase Lake Mead...The issue of how big a hit the Vegas area is going to take from current events, yeah, we're very concerned about that. 

I had to pick up a certified check.  

If you now want to renovate it using BRRR, you will probably need at least 6 months depending on the ability to put money aside and buy the materials and in some cases get the experts to renovate the place you bought.People here on BP tell you that BRRRR OOS is not a good idea, especially when you just started.

In either case you can try contacting whoever you worked with to get the loan and see if they can help.I would also make sure that I had sent a certified letter to the attorney explaining the problem and demanding resolution by a date certain. 

I am far from an expert though, go the CPA route as mentioned above 

I did not know certified accountants could "practice" in different states.
