Beacon is no longer on the list of viable STR towns since they require a STR to be owner occupied. 

I would then find a 2-4 unit deal that I could put down a 3.5-5% down payment on as an owner occupied rental.

I am a co-owner of a Real Estate and Property Management Company here in Indiana, and we work with TONS of out-of-state investors (many from California!).

Even the Cybertruck owners.8.

With a natural in and use owner occupied housing, you could likely end up with 1-2 houses a year (each in a new city).The other option is when your baseball career is over, you will most likely end up back in your home town, so you could start the brrrr process there with maybe your parents checking in on the work the contractors and property managers are doing.Best of luck.

I help business owners and investors raise capital usually connecting them with partners who can secure $75k-$100k at 0% interest for 12 months.

While the owner is free to sell the property and the information about how they run it as a business, AirBnB does not allow them to sell their online identity for the platform.

Your management fee is way too low, especially if you're doing everything for the owner.

Every one of the owners he is under contract with will tell you to run from this builder (law suits in the works).  

Most home owners are only familiar with California Closets pricing and automatically perceive closet fit outs as being expensive.
