See below:So my advice, get your 10 Fannie Mae loans, then refinance the bulk of those to a commercial blanket loan and open up your Fannie Mae slots again for more residential purchases with the best terms.

So calling it unit B is not going to help me one bit or for that matter the mailman.The owner next store took down the mailboxes as they're subject to vandalism, and have the mailman deliver the mail through the door slot.

My partner had slot of cash on hand and wants to invest, I have little to none to contribute but found a property, can serve as the property manager, am able to provide value based on my experience.

It let us drop our interest rate and free up loan slots as well.  

The mailbox is one of those where you just put it in a slot so it was never marked vacant.

lol  Again, IF no attic in that space, You could still install the Ridge Vent itself on top of that 12ft peak area, just not cutting out the decking there (not cut slot under the vent!).

While all 8 slots are currently filled, one of the selected individual may not be be able to attend. 

I'd like to get other people's opinions but here's what I was thinking on pros and cons.pros: low down-payment, high leverage effectively a hedge against inflation, use up unique fha loan slot, get a second rental, I can get capital gains by building/buying for 5% less than market value. 

If you don’t include utilities in the rent, then do you still need to add a value into those slots ?

This is pretty much what most people do, they use their one and only 2nd home slot for their first STR, then you are stuck with investment loans thereafter.
