I would only recommend moving on this if you are comfortable owning it for the long term.

If you don't care about making money as a rental, that is my recommendation. 

I’d recommend saving that $295 cash flow for some amount of time until you have considerable cash reserves saved up.

For those who manage your properties out of state, what door locks would you recommend?

This is what I recommend to new investors who contact me asking if these numbers look good. 

Regarding PMs, I have good ones in Columbus and Cleveland to recommend if needed.

I'd recommend newbies get 2-3 estimates for each product from different contractor (hopefully ones that come referred or at the very least highly rated on a platform like here or Angie's list).

Wondering if anyone has any recommendations for a normal investment property refinance.

I recommend that you find a trusted or recommended Mortgage Loan Originator (MLO), who can give you options for property-based loans (mostly investment loans) and they don't use your taxes but the P&L of the property.

I would recommend seeing what other STR's similar to yours are market as for number of guests.
