Well done on a successful deal.

Find one that has flexible spending options as well as the capability to skip trace LLCs (which is a double skip process).

Looking at outside markets can work very well, but you must have a team in place prior to purchase.

And you mentioned it's zoned residential, well a camp site is not a residential use, so now we have zoning to get through for use variance maybe. 

I just bought an SFR home in New Braunfels and it's been slow go there as well.  

That said, long-term the appreciation you get in the Puget Sound region is superior to many other markets, so assuming you find an excellent property management company that is able to screen tenants and only put in very well qualified, vetted occupants and you experience limited issues over the holding period, you'd likely come out ahead retaining the Mill Creek property if your financially able to do so and still buy wherever you are headed out of state.

Here are pockets I focus on for cash flow:West side - West boulevard, Cudell, Clark-Fulton, Jefferson, Bellaire-Puritas, Old BrooklynEast side - Fairfax, Buckeye-Shaker (the north side), Waterloo Arts District, Garfield Heights, Maple Heights, Newburgh Heights, Lee-Miles (the north side), BedfordHere are the areas that I focus on for appreciation:West side - Lakewood, Edgewater, Old Brooklyn, Ohio City, Tremont (above 490)East side - Buckeye-Shaker (the north side), Waterloo Arts District, Fairfax*I have a graded neighborhood map of these areas as well if you would like to check it out.

They have run STR in Cleveland for years and know the area very well!

Ideally I have skin in all three options for buying and holding as well as BRRRR down the road (diversifying).

Choosing the right location is the most important, as well as understanding its risk/return profile and decide if you're ok with it.
