I am a fan of KISS in most things and this is not an exception.  

Quote from @Glen Wiley: I am not a big fan of those rules - I think they are too simplistic.What will your interest rate be?

Ha, huge fan, I just made a video about the book from Chris Voss!

Pro tip--make sure your exhaust fan in the bathroom is vented to the atmosphere--meaning out to the outside.....go out the roof or out the side of the unit or secured to an opening in a soffit vent grille off the house. 

I've also never been a fan of investments that are subject to scarcity myself and feel that it's no way to gain FI.

Or I've seen a few of them pay cash or do 50% down payments, which of course they will "cash flow" (I'm not a fan or doing over 20% to 25% down).

Quote from @John Litz: I am not a fan of the arbitrage system.

Fortunately our remedy was fairly simple, large floor fans and new ceiling tiles but it was a massive inconvenience and the damage would likely be much worse if it repeated in units in other places.

Never buy without personally inspecting and approving the property and INDEPENDENTLY, INDEPENDENTLY, INDEPENDENTLY, verifying everything from values to market rates, to approving tenant selection procedures and standards, to repairmen on standby, to everything else in Christendom that you can thing of.I am not a fan of out-of-state investing, especially for those with less than 50 years of experience, and for them, they’re probably too old for the hassle. 

That being said, I'm a fan of the buying distressed, forcing equity and either selling or refinancing.
