As an experienced investor, and frequent user of the website, I would have expected you to refrain from personal attack and insults. 

Eventually, a lender will say no more, loan concentrations to one borrower or to the types of loans, policies change. 

Suggestions on what area I should concentrate on here in Lex?

Frequent buy and sell eats into your profit.

Learn all you can about different types of REI and choose a concentration (wholesaling, flipping, buy &hold, notes, etc). 

@Jackson Long  this question of why don't the TK providers just keep them all is asked quite frequently.. but I think I can answer1. some of these guys do 20 to 50 houses a month.. not possible to get them all financed long term.. its all short term debt.. ( ask me how I know) lol.2.

I primarily invest and work in areas around Lexington but there are a pretty good amount of people on here in Louisville & REI groups that meet there frequently.

I have read many similar forums over the past few weeks and found that while people debate the pros and cons of an LLC frequently there seems to be no discussion around the limitations of using personal umbrella and liability insurance to protect your rental properties.
