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

No rent control. 

I am from Uruguay US Market is different than Rio de la Plata. 

Control everything but own nothing. 

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. 

Self defense training, situational awareness, pepper spray and de-escalation are all good.

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

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

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

Other countries have significant controls to this the US does not have.
