You won't be doing your brother any favor by "taking over his payments".  

Or suck it up and hope that the odds are in your favor so you can collect the cash flow you would spend on a property manager.When do you advise to get a property manager?

(A $1K judgment against me became $1,500 in favor and I did collect.)

Until then, do yourself a big favor and call a lawyer.

I would push back for any draw fee's, inspection fee's, admin fee's. etc  These are junk fee's and unless you are getting really favorable terms you should not be paying them (or they should be very very low costs). 

The assets of SDIRA A now include Owner B's IOU in favor of SDIRA A, and the assets of SDIRA B now include Owner A's IOU in favor of SDIRA B. 

Nearly every deal is a multi-offer scenario, so the market is really in favor of the seller since they can easily turn to the next guy and sell their home for full price.Currently we're experiencing a mass exodus from the Bay Area, and tens of thousands of people are leaving for surrounding counties because housing is so much cheaper.

I looked into them on this forum and they seem much move favorable (higher returns in the low teens, relatively hands off even if they turn NPN).

The LLC seems to be the most-favored form of ownership (certainly the most-discussed in REI circles).  

These days I am favoring an investment strategy that allows me to buy into a portfolio of 10 SFR at a time, and co-own with the managers.
