There may be restrictions on when you can exit and how you exit.

If everyone took the cash for keys approach, then the odds of a LL getting such a tenant increases.I have never had to do a cash for keys.  

I have heard there are FHA construction loans but that they are pretty restrictive and do not allow for multi unit construction.

They are very nice and can be helpful providing you what you can and cannot build on your property (Set back, height restrictions, front look etc).

That seems odd to me. 

Have you asked if there are any deed restrictions on the property?

As mentioned above, Portland has more restrictive rules than most of the state of Oregon.

These 2 platforms don't focus on MTR but vacation rentals so using Furnished Finder is a better way to get those longer term folks.I have always been a bit concerned about the area's penchant for restrictions.

I don't know if SF County has restricted the AirBnb licenses.Jens

That truly determines the successful from the unsuccessful, making it happen despite all the odds against you.I have a similar story of finding real estate and achieving financial freedom over the course of 4 years, going from 0 to over 300 doors.
