So I really wanted to gauge how active investors perceived earning additional return on their investments from the actual profits generated. 

I would ask them a few general questions about the property to gauge the condition.  

Solid demand motivated by low interest rates, coupled with tight supply, put upward pressure on prices in the last few months as the home buying season remained competitive.

I know this deal doesn't reflect an entire zip code... but it's cheap and low HOA am I not accurately gauging demand (rent prices?).

I would think it should take a year to gauge it.I'm not a big fan of the "can I bring a buyer Google template". #1 I think you should have an active buyer to want to bother people. #2 If you really do have an active buyer, that message should be genuine and not a canned "template".

Would love some feedback on starting a business plan and ways to properly gauge a market as well as more books you'd recommend to increase my financial IQ.  

As you have probably deduced, I'm still a student in high school; I'm a senior, and I'm still trying to survive the tremendous pressure of being a high school student while actively learning about investing in real estate. 

This ones tricky bc she's not under credit pressure since the note is not under her name.

Then there's no pressure to 1031 Exchange and you can find a better cash-flow investment at your own pace.

I would not pressure your Dad on it if he does not have a passion for getting into it like you do.
