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.

I didn't stick around but I saw the video from the day before. 

The first is that I came across a few websites and YouTube videos that suggested in a quit claim deed a mortgage doesn't transfer from seller to buyer - is this true or false?

@Dan Handford@Jeff KehlThese are in depth questions that you can't get from watching Youtube videos.  

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 

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

Perfect.I should have figured you would have it, after watching you and Steven on Youtube several times.So, In response, I just now registered with Offers2Owners and I am going through the videos. 

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