Drew, in particular expanding on Joe's initial comment (as I was going to request more detail...).I suppose I wanted to be sure I wouldn't fall into a situation where my ability to conduct business is adversely impacted should a central contract not work out.

If the numbers work out and you can put the deal together why not.

Then in the event the other 2 (or one of them) doesn't work out, you have a pre-priced backup that will preserve your 1031 exchange and give you a professionally managed income-generating property that has the potential to do another 1031 in the future at the end of the line. 

One of them we got signed up and leased out that week, the other two didn't work out, but we got that other unit rented out the following week.

What if the numbers work out great and you have found yourself a good opportunity?

Do the numbers work out pretty close to what they advertise? 

Loan terms were good but numbers didn’t work out after analyzing the deal.One question though.

Being new to the bigger pockets forums,  I'm not sure what I'm allowed to say,  so I'll just hint VERY strongly...

I want to give you one of my hacks that will help you beat out the competition and close on a deal sometimes for even less than your competition.
There is a section you can add to a contract called Escrow holdback. ...

This is a great option assuming the numbers work out and you can service the loan payments.
