Can anyone suggest beach markets in SC and/or GA that allow STRs and cash flow with 20% down?

Aim for 720+ for best rates, I suggest start building relationships with your local lenders.

I am 70% thru the materials and will likely go back and do a quick review of all materials before siting for the exam.

I suggest you find other sources of income or partner on deals to grow your real estate portfolio.  

I'd be happy to review and price it out.

Quote from @Stuart Udis: @Danielle B What data are you relying on that suggests Section 8 leased properties provide for better returns than other investment strategies?

Any insight or suggestions you could share on looking for a property?

Withoutknowing the details I can not suggest which would be right to add on.Several you should pay attention to are:- Ordinance & Law: Provides additional building coverage to deal with rebuilding costIncreases due to changes in Zoning or Building laws- Personal Injury Liability: Libel, defamation of character, wrongful imprisonment, etc.

I would suggest starting with reading the IRC book all the way through multiple times.
