What does the BP brain trust think about how this new tax bill in its current or expected form will affect us? 

There was also some broken pipes in the basement. 

Expect nothing and you won't be disappointed.

How much cashflow would you expect to make it worthwhile? 

With values on the rise and interest rates expected to go up it could cost you quite a bit to wait to find a perfect deal. 

Unless you expect steep appreciation negative cash flow in investment properties is cash flow prohibitive.

I expect a price drop by December 2018 to July 2019.When 4 to 10 unit multifamilies become easily available for say 150k or less then maybe we will invest in Kalamazoo again.It is a very decent market when priced right but you have to buy at very low prices to compensate for the low rental rates.  

Can always expect minor expenses though.

On a side note, if your uncle passed away after age 70 1/2, the IRA can generally be distributed over his life expectancy which will help your father in spreading out the tax payments.

Bank does not respect that, it either expects me to rent it out or sell it before I secure the loan of the second one.
