3 questions - house in SD - REI clubs - borrowing from TSP

[Mark Gingrass]

I accidently posted this in a different forum, sorry for the double post.

I own a house in South Dakota but live in Oklahoma now.
I have a negative cash flow from this house of about $150 month.

Do you think I should hang on to this house for a while to see if I can turn a profit, or am I just trying to hang onto a lost cause? I happen to believe that if i spend that $150 on the house, then i'm at least not spending it on more "toys" and junk for myself.

Next question:
In OK City their is a Real Estate Investment club that charges 200 per year. THey have meetings once a month. I believe they have more lectures, etc but you have to pay for those as well, but at a discounted member rate. For a newbie to the Investment world, do you recommend I join this club? I hope to meet some good people though it.

Question 3.
Has anyone borrowed from the thrift savins plan for renovations or even as an alternative to using PMI?

Thanks for any advice.
