This is from Housing Wire "Now, the Treasury has clarified that a business qualifies if 50% of its employee’s hours or wages are from inside the zone, or if the property and managers needed to produce 50% of the revenue are from inside the zone."

You should be developing strategies to get in front of owners/sellers directly.As far as who these buyers are, this entire year has seen a lot of cash move into real estate:1031's finally able to get a fair price for their relinquished propertiesFlight from the inflated stock marketRace to lock in the fleeting historically low interest ratesPeople seeking tax benefits of real estate not available in other assetsForeigners sick of the abysmal returns on treasury notesThe good news is that very few of these buyers are talking to the owner of the fourplex down the street and establishing a rapport for a property that is not on the market.Good luck.

It's not illogical to think that way, but it's ... an immature way to look at valuing an investment opportunity.Think of CAP rate the same way you might think of bonds: a treasury bond (the safest investment out there) might give you a "CAP rate" of 3.5%.  

Generally a good indication of mortgage rates is the 10 Year Treasury rate. 

Will this ultimately affect the 10-treasury bond that drives mortgages rates?

The overnight/prime rate increase doesn't affect the 10-year treasury bond that mortgages rates are tied. 

The "risk-free" 10-year US Treasury rate is currently 2.27%.
