Before you do anything drastic like moving assets into an LLC or start paying off things do a "whatif scenario" through one of the bureaus or a "wayfinder" scenario that tells you specifically what you need to do to bump your score on each bureau. 

Hi, I'm seriously looking to became a property Investor, with small flats or condos, basicly fix them and flip them with a quick return.I am trying to find funds in order to finance this enterprise, willing to select one by one property and sell, then move on to next one.My question is anybody in the community could suggest the best option for financing these quick investments?

Now my credit score fell to 665 at Equifax where my other bureau scores are over 800. 

Apart from the Census Bureau, where else should I look for data?

HELOC lenders tend to only look at one bureau, especially Experian in my experience.Have you considered changing your refi to a 30yr?
