The needs of real estate investors are very different from the needs of "normal" insurance clients who just live in a house they own, and drive a few cars.PLEASE, for your sake and the local market as a whole, only work with insurance professionals who can demonstrate a deep and thorough understanding of your needs as a real estate investor. 

Our properties are completely renovated, have qualified tenants in place paying top market rents and are professionally managed by one our trusting partners.

This isn't something I would leave to Bigger Pockets forums the laws vary widely by state so it would probably be best to look up the law or talk to a professional in your area, (not over the internet) who knows what they are talking about.

As far as some general criteria/thoughts:- My workplace is in the Cobb/Vinings area and I would ideally like to be a < 30 min drive to work (though I don't mind if its up to 1 hour away since that is my current commute)- I'm interested in using a FHA loan to put ~5% of a down payment (3.5% down pmt + 1.75% upfront mortgage insurance premium)- My target all-in purchase price range is between 200k - 400k - I would prefer to live in a 'A' or 'B' class property that I could rent another unit to a young or established professional/college or grad student- Just from discussion with my friends, a lot of them seem to dig living in areas like Midtown, Buckhead, Virginia Highlands, Brookhaven, Lindbergh.. how feasible would it be for me to househack in any of those areas and expect to generate a decent return in the future once I move out and rent out my unit?

@Josh Guo you may want to check the marketplace you can find professionals offering their services there 

I am currently throwing money down the drain by paying $850 in rent at the moment, and noticed that I can be paying for a mortgage for almost the same price.

So be sure to check with a local tax professional.

I have heard about all the nightmare stories regarding people that signed leases without seeking professional help, so I was wondering if anyone can recommend a good commercial lease broker that represents the tenant around the Philadelphia area

There are times when you need to just pay the professional.   

Any professional painters out there?
