The permitting process and the availability of reasonably buildable lots is a concern.   

The booker is less concerned about the price as they are getting the workers' housing settled efficiently.

You wire funds to a company that is in the business of building buildings, they create plans, get permits, raise additional capital, supervise construction, supervise filling the building with tenants, sell the building to an institutional investor, and if everything has gone to plan then there will be a significant profit and they wire you back more money than you put in.

My preference would be areas with tech workers, software professionals, etc. 

When it comes to acquiring lucrative coastal luxury vacation rentals on the Oregon Coast the most challenging components can be permitting and timing. 

I would check with an attorney or CPA on it.EDIT - Check out Scott Royal's site - https://royallegalsolutions.com/what-states-are-permitting-s...He used to be on here quite a bit but I haven't seen him in a long while.

You also should call your local zoning or permitting department to get information on areas you are interested in and how to be a legal STR.I 100% recommend making sure the STR could work as a LTR as well in case you have to pivot ever.

Said differently, you won't need a special ADU permit to create an ADU.I'm interested in potentially purchasing a single-family home in eastern MA (Norfolk or Middlesex county), and doing this exactly.

I have heard Boise was cracking down on permitting, so make sure you can meet all licensing requirements and that you are in an area zoned for this type of use. 

If you do fall within either, you are permitted to ask if an animal is a service animal, and (if it is not obvious) what task(s) it has been trained to perform.
