I can only imagine how bad it can be with 10-15 flips a year.

I imagine there are some very specific tax strategies for non-performing note investors. 

You didn’t state whom the seller is but if it is a Federally owned foreclosure such as Hud or FNMA, it is a federal crime to modify the property in any way or take possession prior to closing I cannot imagine any bank is going to extend the closing 2 months

It looks like some concrete in the driveway needs re-poured, maybe one/two pads. 

You could also pour all cash that you make into the property so that it will be all paid for when you finish it.

However, while I am not familiar with that market in particular, I would imagine that competition on the larger properties would be just as stiff as in the duplex and quad market.

Imagine me trying to go into the city, after working on late 1800's farm houses and building barns to value add, then going into the Museum district.

I can't imagine banks are gonna start guesstimating markets to make a extra 20k on a property that they have to up keep and pay taxes on.

I imagine managing the properties yourself is a full time job, and if anything were to happen to my current one I would not be against it, but can't for now and would happily have a property manager.

I can hardly imagine the frustration and stress this has caused you and your wife.
