loan on undeveloped land

I have 4 acres of undeveloped land that I need to get a loan on. It's assessed at $23,700, which is below market rates for that area. I have a good credit rating, but at the moment I am in a bit of a gap as various projects are still in process (I'm not building). What is the going rate for such a loan? There is very little chance that the lender will end up with the land and I would happily give a generous rate if I could get any sort of decent loan o the property. How much could I expect to get as a loan? I know it won't be as high as I would like, but since I'm expecting to pay it off within a year or so, I'm not too worried about it. Any suggestions? The land is located in a growing community in Iowa.
