In theory your thesis sounds like to might have some validity, BUT, in my 45 + years in real estate I have found little or no correlation that I can see.  

So with careful mortgage planinning between your title timeframes (title seasoning as lenders like to call it), planning your income or tax returns, and how long you live at each property while you're house hacking them you could in theory get a HELOC on each primary residence before you leave them and buy the next. 

All great in theory but not going to really learn anything unless you get out there and do it.

I have a theory that Twilight drone shots are hard to beat, but others would argue differently.

I’m no longer involved with those businesses so have ample time for focusing on this lending idea.I consider myself “semi-sophisticated” when it comes to investing, and also enjoy learning about legal processes and theory.

Absurdity at it's best.My personal opinion is that theory of the legal process and the actual application of the process are two entirely different things.

We have found building and nurturing existing relationships has provided best bang for buck
