I know the cheaper $10-$40k houses tend to work better for landlords & rental/cash flow rather than re-habbers.

I live in Nashville, and I've made some solid connection with my association and I'm actually planning on checking out the ATL one to get my family bitten by RE bug that are in ATL. 

I can see a benefit from not having to re-key a property and offering the smart home system as an incentive for new tenants, has anyone thought of this for their duplexes or multi family units? 

Can a contract I agree to buy from a wholesaler be “Re-Assigned” to another flipper/Retail buyer?

You have a seller under contract to sell or assign a property (and you're not a licensed agent).. a licensed RE agent has a buyer. hmmm. 

You're young enough that you have to decide how much RE you want to eventually own, because you have plenty of time to either leverage and get that growth now or go the slow and steady one-at-a-time route.

Generally a REIT might buy a large portfolio and not want all of the properties to re-balance their asset allocation percentages of a certain tenant type or asset class.

You will learn a lot of the do's and don'ts BEFORE you own a property which would be of great benefit.Then, when you are old enough get your RE License and do that.. even part time.Follow a path like that and by the time you are 25 you will have tons of great industry experience and be well on your way to success. 

If it were me, I would probably sell the lots for the $150k, pay off the the $80k in debt and use the remainder to get started in RE.  

Nice to hear your excited to deploy buy and hold strategy in RE.
