Check the source where you found the house.  

As an investor, I rarely, if ever, consider Loopnet a good source for quality deals. 

It's not the end of the world, necessarily, but many people feel that if they can't absolutely maximize each dollar in the most efficient manner, then somehow, they have failed.And in this day and age, the internet allows the entire world to criticize every decision they've made if they decide to share it for some reason.  

The good part about mentioning you are an investor is that if you make the lender feel you know the game really well, they will treat you like a potential repetitive income source.

OK so is using a HELOC a good way to acquire  more properties so that in he future  I can have a good source  of income  with buying and holding 

Like others have suggested, use google or under the resources tab here on BP there is a directory.If you need fast funding and don't have a private money source, I'd say hard money is the way to go.

Would it make more financial sense to dry up my non-portfolio loan sources before doing portfolio?

Wholesalers are a good source a deals to flip and auctions can be too.

Hold no punches, Marines can handle constructive criticism :) 

Unfortunately due to how low quality they are and how many investors they screw I wouldn't consider them to be a good source for information.2nd - We were actually intending to contact the Lucas county and get the taxes lowered with a new assessment before the property is officially sold to our investor.
