I figured as much since you had a bunch of question marks and exclamation marks in there and a few incredulous capital letters :) .

Before myself and a few other builder developers jumped in.. it was hard to sell anything in those blocks of town..

'Your best bet is to wholesale for now- you find a super good deal (how are the yellow letters coming?)  

what did your letter say that got you 6 deals?

It bitcoin IS block chain innovation. 

Let them know about the PM and emphasize that you will keep the property in excellent condition, thereby making the whole block look better.I'd schedule a visit where you stay for a few days, and at that time maybe a gift card would be appropriate......

Pick an area that is within a 2 hour drive or a 3 hour nonstop plane flight.Get in that market and really learn it neighborhood by neighborhood block by block.Local market knowledge is every investor’s competitive advantage.I do MF deals in Greenville SC where I live and already own 400 doors.

Quote from @Eli Ling: also does FO letter mean F@#k off letter?

Then I usually get a letter from the Sewer provider citing the Indiana law which says I'm responsible for Sewer if the tenant fails to pay. 

Quote from @Kar Sun: My tenant's lease is coming to a close and I am relieved she will be moving soon.She has been paying on time but has been extremely unpleasant and rude.While the money does not smell my mental sanity is more important than money in this case.She sent me a registered letter stating that she feels "unsafe because we have not done the fixes the way she wanted it".She requests to have her witness for a walkthrough.In my state a walkthrough is required but I am not about to grant it to her to bring any witnesses as that is not in my contract.If she feels unsafe she does not have t be present.I also do not treat a final walkthrough with a tenant as a final sign off.This walkthrough does not include a detailed inspection of the plumbing and the appliances that will be done after she departs.This is simply for the visible cosmetic issues and should take less than 1 hr.
