We’d have a subsidized tenant, so at least collecting a majority of the rent, and I understand that these tenants usually stay longer.I know there is bureaucracy with Section 8 but can out up with that. 

Stay away from broke negative people and network with people who are more successful than you and be around those like minded people.

We can help you understand your options and guide you through the eviction process if needed.

I have had theft and windows broken in, squaters staying in the back shed.

Doesn't seem lower pay is prohibiting their rentals from staying rented at all.I'm definitely targeting healthcare + education + corporate. 

Here are a few I recommend: "Rich Dad, Poor Dad" by Roberto Kiyosaki; "Set for Life" by Scott Trench; "The Unofficial Guide to Real Estate Investing" by Spencer; "The BiggerPockets Ultimate Beginners Guide" found here on BP; "The Book on Rental Property Investing" by Brandon Tuner.

I have to sell my house and need to stay somewhere until it's sold.- Are there websites where I search for a furnished place for a few months for adequate money?

Go from there based on the results.We often tell tenants moving in that they can stay as long as they pay rent and follow the rules. 

The property will have to stay under his name because of the interest rate, so How can i make him happy, make an investment and have some cash flow for myself ?

That could affect your taxes greatly.I'd recommend researching cost segregation, finding a good CPA to guid you, hook up with a good Realtor, and do it yourself.
