I too am looking for mortgages with good rates and low closing costs. I'm purchasing a 1-bedroom co-op in Alley Pond. I think we're getting close to 5% interest rate, which a few banks are offering now. As well, you want to get a Good Faith Estimate for closing costs and hope the lender stays true to that. Some of my co-workers got 1.5 - 1.6% closing costs, but some realtors will tell you 4%. I will be happy to pass on any information that I find. I am especially trying to find out which lenders pad costs at closing time, so that I can stay away from them.
Ing.com is offering a great mortgage rate and low closing costs.
