Can I deduct the closing costs on a new house purchase?

I received Form 1098 from my lender which shows the interest paid and points paid on purchase. I was able to deduct those. But what about my closing costs I paid when I bought the house? Where do I deduct closing costs when filing taxes?I paid over $6000 in closing costs. Aren't those deductible?Also I paid about $2300 in Mortgage Insurance Premiums. When I added that to my deductions it did not increase my refund. Why? Shouldn't I be getting tax benefits for paying Mortgage Insurance Premiums?
