Yes, it's possible to manage an out-of-state short-term rental without a property manager, but it requires careful planning and the right tools.

Planning to build 4 bed 2.5 bath 2200 square feet. 

What about mechanics, attorneys, bank managers, auto sales, accountants, insurance brokers, realtors and similar?

If you are planning on buying a turnkey property anyway, I suppose it could provide some insight into the locations they are working in and as I said above, if you did buy a property through them...the academy fee is refunded.Definitely don't take my word for it but it's helped me so far. 

If the damage was storm related homeowners insurance might be an option?

(They used to ask for a title but I think I just showed insurance card last time.

After that I plan to quit my job and become a full time investor flipping properties.

I plan to save the rental income for reserves, screen tenants properly, buy in C+ to B class properties. 

The numbers and business plan more than adequately support the project numbers (can share privately). 

However, if you need fast access to funds or have difficulty qualifying for a HELOC, a hard money loan could be a viable alternative, especially if you have a clear plan to refinance quickly.
