Put plainly, what is the process/fees of selling a house?

If you sold your house for 112K and had a mortgage for 90k you would come out with 30K. You would pay an Estate Agent anywhere from 1 1/2 to 2% of the asking price for their fees. Solicitors costs could be 3 to 400k. There might be an early redemption penalty from your mortgage lender for paying of the mortgage early.
