However, over the years the IRS has become very sensitive to the issue of "basis shifting". 

That shifted this year as for whatever reason I saw my ADR with Airbnb starting to erode as my market in Arizona became more saturated with STR's. 

I'm hearing that in some places the market is shifting and is slower. 

Regarding the calculations, I guess my point was that you should shift from running numbers hypothetically for calculation purposes and start using real numbers so you can see what you are getting into.

I have written a detailed business plan on how I plan to start and run my investment  business, eventually bringing in limited partners.I am located in California and hope to purchase my first rental at the shift of the next real estate cycle.

The market is shifting and the margins are shrinking. 10 years of stratospheric economic rise has given the market LOTS of competition and rising interest rates are having a real effect on deals.

Planning on 23 2bd and 10 1 bd but the mix can shift if one bed is better.

@Dmitriy Fomichenko, pardon the slight shift from the exact topic... can a SDIRA LLC be owned by, let's say at WY LLC?

I'd encourage you to shift more towards more tangible 'bottom line' type of goals, or value/meaning type of stuff.  

It took me a while to shift out of the “hurry up and payoff debt” mentality.
