I have around 700 credit score.

It sounds like you're on the right track with Freeport!

I'm building my credit so I can buy my first property.

My advice: focus on building a strong financial foundation first save consistently, manage your credit, and educate yourself on real estate fundamentals.

Jonathan,Unlike credit cards with "Intro Rates", HELOCs are a standard banking product. 

Since you pay the PM for their work, the application fee should only cover the actual costs of pulling a credit report and background check.

Lowes rewards actually gives us more than a $50 tool rental credit and a flood of emails trying to hype their programs. 

I've tried reverse tracking a few of them but it typically says unkown for the owner. 

Because his credit was good and the property was in a desirable area, not value wise, but living condition wise, he got 90%/100% financing on project 1 which is pretty good. 

And to @Jay Hinrichs's point, I see no safeguards for gators when teaching about gap funding, EMD funding, or any other tactic that they try and sell which tells you to get 0% interest credit cards and build business credit to be used to lend out.
