I would return the money and let them decide on the next deal based on the merits of the deal separately vs. trying to roll over their money. 

The retirement type funds that are not associated with your current employment can probably be rolled over into something that is self directed and thus allow you to invest in RE in your area or elsewhere.My advice would be if you're in high profit areas like I believe Baltimore to be (and may become more so with your recent events) would be to do it on a Roth basis.

We were hoping to finish next year at a higher sales price, move out, and roll money into a 4-unit MF fixer to do it again.

Or are they rolled in together?

I try not to refinance unless I have to, I will sometimes roll the loans into one, but I prefer the 2nd property to make its own way. 

While the large franchise brokerage may not be for me in a few years it currently provides me the framework to get the selling side of my business rolling strong... 

lets get the ideas and experience rolling in please.

Your current rent roll definitely doesn't support your current offered price.

You will see some properties continue to roll over if the reserve hasn't been met.

You are also able to borrow rehab money and roll it into your mortgage, which will allow you to qualify for properties that would not otherwise pass FHA criteria.
