I am looking to supplement my income with real estate investment.

Hawkins II and I have decided to become a real estate investor, so that I can supplement my income, where I would like to make an extra $75,000 a year.I am currently located in the Lawrenceville, Georgia area.

You can use Everbooked and AirDNA to get high level estimates for your ADR and Occupancy rates but in the end, I usually like to supplement (especially if I'm getting serious about a property) with good old fashion legwork with calls to local property management companies and review of nearby listings on Airbnb/VRBO.  

They've mastered supplementing their income and don't live beyond their means...

I've been told: 1) that if there is ANY flood zone on the property, even if the house is not in it, then mortgage companies require insurance2) Flood insurance is very expensive (after the first two years of government supplement ends)3) 1+2= longer hold times and lower ARV Are this "facts" true?

He feels it would sell in a matter of weeks or months at 140K or so.I am mostly looking at real-estate as a supplement to retirement income in15-20 years, but some current income would not be frowned on either ;).So , what do you all think?

I have goals to be able to do this successfully by the time I retire for supplemental $$$$.

I have one property in Melbourne and hope to purchase more to supplement my retirement.  

Usually they are allowed if they are used as a "supplemental" heat source.

Either way you need your rent at market as opposed to supplementing your tenants rent every month.
