Refinaning your mortgage.

My husband and I bought multi family townhouse last year. Our bank agent called us for refinaning with rate 5% from current rate 6%. Questions here
1, Anyone are qualified?
2, How refinancing fee is determined? Higher fee for house than condo or for higher mortgage amount?
3, How often refinaning can be done? negative side?

Please share info of refinance with me!

Thanks
