Education by seminars and workshops are hard to decipher whether they are scams or people really wanting to give knowledge.

Just curious...has their inspection period not passed already? 

Fannie will Not allow you to do it, period.

Another way to add value is to network in your local REIA, and provide education.

I liked having spent hours research markets and neighborhood and government programs, so that I felt more educated to have a conversation with my realtor, rather than him just tell me his opinion. 

You will need to get a lot more education before you do it, and for me, I would have to have a reserve before I think about flipping a house.

We also have a growing population of educated professional tenants that will target SFHs and absent landlords.

My first advice is to educate yourself before you start looking at markets. 

How is the continuing education?

This way you get the benefit of the cashflow when you're not using the line and when you do use it you know that it's for a short period of time to help you acquire another property before doing the same thing with that one.
