I'm broke as a joke but I have good credit how do I get started 

If so, invest.It's not let me find some deal for me-- the lowest hanging fruit.

Look at it more like a credit card.

The cons as i see it include loosing the 2 of 5 year cap gain exception, typically not an ideal rental because the emphasis at purchase was buying a good home for your family and not a rental with optimal return (my ex-home consistently has the lowest cash flow for equity in my RE portfolio), not disconnected enough from the property causes addition angst on damage and may result in over improvement.  

I'm not an loan officer, but I know some banks locally like ORNL Credit Union have offered a 0% down conventional loan product.

You may need some help with capital, or credit, or both.

Dedicate one checking account and credit card exclusively to real estate.

Get a line of credit from a bank that leverages your equity without refinancing the properties.3.

Zillow has an easy application for them to fill out. it come back with a credit score and background info. 

I agree local banks and credit unions will be better if you're planning on growing your portfolio.
