The advantages of still being able to easily attain traditional financing because of the W2 job (which pays well) sound like a good idea.  

As I grew up a little I realized that wasn't really attainable in MA unless I wanted to live out west where there aren't any jobs. 

If you were quoted two weeks ago, chances are that rate is no longer attainable at the moment. 

However, I found out that he only works with "accredited investors," which I am not.I was wondering if 18% return (as a passive investor in partnership with other active investors) is still attainable in today's market.Even 15% sound really good.

I think what I am more aiming for is a live in flip something that just needs some updating and refining but is still able to be attained through fha financing.

Your goal is quite attainable, especially considering your creative investing skills. 

you definitely should word with a licensed realtor in Connecticut to attain your goals.

If you want a 10-12% CoC return then that is what you should be trying to attain.

That will be the best way to exit the rat race and attain financial freedom, in my opinion. 

Motivation can be attained for free as well if you surround yourself with the right group of people.
