I follow bogle heads methods for investing in that respect. 

Document each time you've tried to contact the tenant and the method. 

But how do you tell a RE professional that their development methods suck for a new media medium?

You can research the BRRRR method on this site but searching the term.

How do you find the point of diminishing returns for rehabbing as part of the BRRRR Method?

@Chris Tabanico I think this is the course of action I'd like to do;  I first heard about this method back in January and this seems like the best way to go given my situation. 

The benefits of having a 50/50 partner would also ease the mind when getting a first time deal and would hedge my own losses financially if the deal went sour, at the risk of losing a friendship.Investing strategy: BRRRRing SFH or buy and hold small MFH, whichever method has more/better deals and can be agreed upon with partner.Now truthfully so, I’m not really sure what to ask here.

Mind you I do have the resources to make emergency repairs and have no debt on my rental properties so I do not fear vacancies like many do and the pool of cash builds back quickly.I suppose if I was organized or not so darn busy I would do something that yielded better returns but hey it works for me.I do this the slow boring methodical way but so far so good.I know this didn't answer your question.

I'm guessing each state has their own method of sharing what's been nominated.I'm in Des Moines and it appears there are a couple pockets of nominated areas (Drake area and what appears to be around Valley Junction in West Des Moines which surprises me):I am also noticing that there's some great info on both of these youtube videos/websites:https://eig.org/dcihttps://www.youtube.com/watch?

Should I try the BRRR method?
