Optionally, use an irrevocable trust for added estate planning benefits, though it limits control.

So that was my first partnership, we bought houses and I controlled the whole process and I learned so much.

Well, most of those OTAs have a bunch of premiere partners and still have plenty of limitations on what exactly can be controlled via API and whatnot, so that's not really saying a lot.Doubly worrisome is that there are almost no hands on reviews of Hostaway, and any time the name comes up on BP or Facebook groups there are suddenly a dozen new "users" whose first and only post ever is to talk about how great Hostaway is, without providing any details. 

Control everything but own nothing. 

In-house means more control—you’ll manage everything from printing and stuffing envelopes to postage.

First step would be to talk to the controlling government body about what you can do with it.

No rent control. 

You have a LOT more control of cash-flow than you do appreciation.

They need to do all their due diligence including understanding the value that will be added by the ADU, the finance options available, the consequences of adding the ADU (rent control, property taxes, rental limitations, etc), etc.Good luck

There will always be some sense of resentment or issues that you leveraged control ect.
