This strategy would accomplish your current goal of obtaining LTR properties and also being able to recycle your cash indefinitely(at least, that's the goal of a successful BRRRR).

I bought a great little home at a great price and great interest rate last Fall in Washington, DC, where I live and plan on staying indefinitely.

For me, there has to be a viable exit strategy to pay off the HELOC in less than 12 months, that frees up my line so I can do another deal and I also don't want to have a large balance on a variable rate indefinitely. 

IF THERE ARE INDEFINITE LAYOFFS AS THEY SEEM TO SUGGEST LANDLORD WITH MORTGAGE WILL TAKE A HIT ALSO.

I suggest, start with one, learn along the way, then repeat, indefinitely.  

Definitely would need to know more about the process and what's expected.Possibly templatizing this and follow up with metrics would be awesome.Thanks for pitching in - definitely something to think about.

But realistically I think there will be stifling regulation for a very long time, if not indefinitely to the point of failure.

Some servicing contract stipulates the timeframe so you're not chained to it indefinitely. 

J-tree (San Bernardino County) just changed some rules and are considering a moratorium or cap, Palm Desert does not allow short-term rentals for a while now (I had to convert mine to 30+ days), and Yucca Valley is not issuing new licenses, originally for 45 days but expected to be continued indefinitely.

Lastly electric is hands down better than gas cars, maybe aside from the engine noise a sports car makes, it is finally clear it is the direction we are going and should have been going many years ago.
