It all depends on how muuch you put down and if you want to roll the insurance and tax escrows into it. Also depnds on your credit.

With good credit your principal and interest would be 1348.00 (thats on 237,500, assuming you put down 5%)
Then you can guesstimate about 350 dollars for your escrows.
