The point is to not have them hurt so bad that you stop investing, or find yourself unable to invest anymore.Finally:Follow the three immutable laws of real estate investing (tm @Joe Fairless)1.

@Joe S. 

Joe, thank you? 

@Joe M.Find a local property manager who can tell her what the local rents are and how far under market they are now, what interior finishes other units have (a contractor to tell her what those improvements will cost), and what they would lease for after repair.

Joe, I’m also in the auto industry where there is a lack of Supply and high demand.

@Joe MathewI use smart move from TransUnion for credit and background checks.  

I'm with @Joe Splitrock on this one, if he is a good tenant and paying leave it be. 

I like to leverage tech and it's really gotten better the last couple years.The type of deals I'm interested in are wholesaling lease options ala Joe McCall(his software is REI SImple), and/or possibly doing land deals ala Jack Bosch (his software is Investment Dominator).Then I learned about Propelio, and it seems pretty darn comprehensive and comes with a ton of training.I do recognize the advantages of systematizing, and so at some point I will likely want to pull the trigger on a system to help me. 

@Joe SplitrockGood catch!  

@Joe SplitrockThank you for the response, Joe.After I thought about it, it seemed like a dumb question.
