The most common general answer I've received is keep it simple while your small.

I focus on easy management, so keep my units in a small radius so that my maintenance guys, and various service provider companies such as HVAC, plowing, and plumbers are common to all buildings. 

I don't see how it makes sense for a lone investor.  

@Tyler HuntingtonI will assume your pro-forma on the expenses is accurate, and there are no common areas where you might need to pay for electric to a light or two; tenants pay for water, sewer, trash, etc.My suggestion is to look hard at your acquisition costs.  

This is common sense.

@Joe Bertolino and @Matt Motil that makes sense that something that doesn't look like marketing material is much more likely to be opened.

I am not sure if it makes sense to invest in a MFR now and get a solid PM and tenants, or to wait until we get back and invest.

As far as your question goes, you can try to close both if that makes sense for you or you can back out of the deal (it happens in real estate quite a bit and with short sales all the time). 

The deal will sell itself if the numbers make sense.

(The first thing that occurs to me is an "herbal" dispensary, but that's just because I have an unusual sense of humor.)
