Anything is possible but cost may make it cost prohibitive. 

@Michael Ealy  In MA, CA and MI (the three states in which I've taken the time to research the actual RE laws), selling your contract is prohibited unless you're licensed to sell real estate.Double closing is 100% legal. 

@Mike G. my initial reaction is to get a new lender as quickly as possible...most people do not think of a 3 or 4-unit building as a "single family", but it is...we only really move to multifamily at the 5 unit mark...What is the setup of the property...triplexes are very rare and oftentimes are comprised of more than one structure...on the same parcel...the only issue I can see is if this is non-conforming...maybe a SFR and a condo...or condo and duplex...something like that.In reality, the only thing that would prohibit you from getting your offer accepted is the competitiveness of the market...you actually would have about a 4% of getting an FHA offer accepted here...hot markets and FHA loans (especially in locations with older properties) is a fatal combination...most listing agents would advise to not accept and FHA loan because they are inherently problematic at both underwriting and closing timelines...you are almost always better off with a conventional loan unless your credit score is low...What else is going on with the situation?

Did you prohibit the landlord from agreeing to new leases.

are you saying the Federal rules prohibit the assigning of short sales negotiated through a lender?

I do own and manage some buildings, however, where some or all pets are prohibited completely regardless of references or similar.

Given the break-ins, he requested a dog for his daughter, but our current lease prohibits pets.

Would this be a prohibited transaction- Let's say I purchase a commercial office building with my SDIRA and lease that property to my full time employer.

If they have a regular mortgage, there will be an exclusion prohibiting vacation rental activity most likely.
