It's the foundation of a portfolio, and then once happy with your cash flow I like to start going for "better houses" and diversify location.

The issue I am finding is it's unique location. 

Is Charlestón, SC a good location for AIRBNB?

We are located in Alberta Canada if that makes any difference. 

Most likely the state where the property is located is where lawsuits would be brought if they are something for personal injury like a trip and fall or something of that nature because the “cause of action” arose in that state.

I just had half month's rent as security. 

So make sure not to rely too much on securing the CalHFA loan.

The FHA Lender list allows you to search for bank branch office locations that have done at least 1 203k in the past year. 

I am located in Jax Florida and use my realtor license for personal deals and occasionally help others. 

The property owner let the building decline for many years, but the location is prime.
