I've heard that a plan well conceived is already half achieved.

I can totally conceive of a profits interest here for pure services--e.g., the % you might pay to a property manager plus a few other incidentals.  

So your scenario works just fine. depending on timing it's conceivable that you might have two properties qualifying with your residency but waiting for the two year wait to end so you can sell the next one and take the 250/500k exemption.

Even if the designs are truly eye catching and unique, I suspect a business based on tiny homes will be unprofitable unless conceived in a booming city that has a surplus of small lots and people ready to change their lives for a real reason like surviving property costs.

The key to me was to create a "calendar" with all of my available slots, look at who is going that I would conceivably work with, and then reach out to them to schedule a chat prior to leaving for the conference.

There's no official limit so you could conceivably get a bunch at the same time. 

Might be just a pre-conceived notion in my thoughts that was wrong.

When baby #2 was conceived, I knew it was time to get out of our 2 bedroom duplex that we rented.

Whatever the mind can conceive and believe it can achieve."
