We just don't have the exhaustive resources for commercial stuff here like we do with residential. 

Hey BP, I just finished the remodel on a 200 year old log cabin and wanted to share the results after this exhausting remodel. 

I have seen things like exhaust fans not being connected.

We have always pushed for >12% CoC & quickly abandoned the exhausting, mind numbing idiosyncrasies of just being residential Landlords, except for maybe 8 properties our kids still hold, for their experience.There are so many ways & niches to accumulate significant REI wealth & having the foresight to tax defer the loading/then implementing of 401(k)-solo's is an excellent beginning.

But this isn't an exhaustive list, and to me in Cincinnati, these are good signs and hold true in many up and coming neighborhoods. 

So, mitigation is the more profitable action to exhaust first.I think best play involves typing up Brothers share and bulletproofing deal without much of any cash now.

Working a 60 hour professional job while building a real estate portfolio was exhausting.

HMLs are about the last resort, the title lenders of RE, high interest, high points, short term collateral based commercial lending, certainly some are better than others, but I'd exhaust banks, credit unions, brokers with private money before looking at an established HML dealing on a national scale or even regionally.

And then I was just exhausted.  

What if two years from now they go up to the attic and notice an exhaust fan that terminated in the attic and not vented outside, or they wanted to add a receptacle somewhere and hired an electrician, and the electrician told them they can't and because the junction box has too many conductors in it and it exceeds the box fill capacity, so they have to pay to open the wall for a bigger, deeper box or piggy back another box...do they send you the bill too?
