I'm just thinking that I made the mistake of telling them my intentions (that I wanted to rent out the other units), but I'm just curious if it's a federal law with buying multifamily properties.

We bought it with the intention of renting it until we're ready to retire, so selling now feels like we're upending our plan.

He bought the duplex with the intentions that when his sons got old enough to attend the local university they could live in one of the units and have their own space and still be close to home.

That’s like saying consumers should know all the tricks and ways an Auto Stealership intends to extort maximum profit from the ill informed.

My intention is to wholesale the property, typically I would blast it on CL and FB marketplace but I feel that I can’t do that in this situation because of the agent.

I'd also like to get my license so I can can buy/sell my own properties, get MLS access, potentially make a few bucks on the side or perhaps be a "full-time" agent after I have kids so I can keep my resume current and work from home...but I'm stuck on finding a broker who will let me hang my license with them knowing I don't have any intention of being a traditional, full-time agent.

Do you have any evidence whatsoever that his intentions were nefarious?

Ill send his cell # over PM. 

Don't sweat it.Do not listen to guru's who tell you to run around promising to buy everybody's house for cash when you have zero ability or intention to do so.

This particular deal is a little different from your normal investment as it's intent is to be rented until my family and I are ready to fill it's walls with our own photos and it's floors with my son's never ending accumulation of toys.
