cashing an IRA after first home purchase?

To give you a short version of the story. I bought a house, the real estate agency grossly misquoted both the closing cost and the monthly statement. It was within guidelines for what they are permitted to be wrong on (mainly taxes), and the seller would not let me out, he had a lawyer. I am $70 a month over what monthly cost was expected, and out over $1100 on closing. I have a small income, and can't afford the extra, I was at a limit on what I consider a safe budget with original estimate.

I have already purchased the house. Can I still withdrawal the IRA and avoid the 10% penalty charge? I am a first time buyer, and the house needs repairs, would I need to keep receipts? That would probably put me about 25-35% below the IRA value after tax? If not probably 35-45% below the IRA value?

I am under 59. I have 1 bill I could pay off with 65% of IRA's valued that would saves me $82 a month. If I don't do this I will likely loose the house in less then one year.

Cashing the IRA is necessity unfortunately if I want a chance to survive.
