The real estate melt-down in 2008-2009 necessitated my unretirement...After looking for some other way to rebuild my retirement portfolio I have circled back to real estate as my vehicle of choice.

Well, here comes Hurricane IRMA and screws up one of the target MFs necessitating a new roof which the seller refuses to negotiate on.

But I can control that the tenants have no violent crimes on their criminal report.I do not think managing in a C area necessitates dealing with criminals. 

If you have water heaters exhausting up interior chimneys then be aware of possible leakage.Recognize that every job which you have to do has the potential to spiral into others- I have found a number of patchwork jobs when we went to do work that necessitated doing more work than anticipated. 

So now as stated I have 3 communities going and so I have 3 separate developers licenses.. 3 separate bonds  3 separate insurance policies. and I am closing on a big 90 lot project in December which will necessitate yet another set of licenses bonds and insurance.. 

If you have ownership, will owning the properties necessitate a 1040NR with Sch E for you? 

its not my logic someone who closes on a property before reselling is known as an investor.. and or rehabber or investor flipper.assigning contracts is bringing two parties together for compensation ( definition of activity that necessitates a license in most jurisdictions including CA .)  

Buying a house for myself would necessitate a 4th mortgage.

@Minh Nguyen The majority of the time we find that the occupants don't abide by the agreement reached at the courthouse either, necessitating their removal by the sheriffs after they breach (which of course takes yet more time).

Nothing has changed in your life that would necessitate not living in the pproperty.
