Will the fact I’ve used a lot of my reserve line hurt my chances of getting approved for mortgage?

I have a bank account with a reserve line back up. My limit was about 3000. I’ve used about 2000 in last couple years paying some than using some more again when I didn’t have a job. Will this on my credit report hurt my chances? I am lucky to have someone co signing and helping me with a downpayment, but my account and that reserve line are not too great.
Oh and I have almost 800 credit but have student loans as well….

I would like to know if the mortgage rates are going down this month?

I heard that the mortgage interest rates are going down this month. I wan to refinance my house…loan amount is $453k, fico score of 640, SFR, no cash out, full documentation and reserves and my loan to value is 65% . I don’t know if I should refinance now or wait a little bit more. I would like to have more informations about 12/12/07.
Please advise,
Thank you

How much will the average mortgage rate drop by the end of September?

I have already prepurchased a home and locked in at a 10/1 ARM for 6.125%. I have a one time chance to relock within 60 days of closing. I will be closing in about 30-45 days. Will the rate drop below this or did I lock in at a good time? I hear the Federal Reserve will be lowering rates before the end of Sept. but will they be below 6.125%?
