Hi. We still own our house in the UK and our mortgage is with Santander (Alliance and Leicester) and we pay them the nominal admin fee of £100 per year for their consent for us to let the house and have just changed our morgage to a tracker. They did not quibble at all when initially we spoke about renting our house out nor did they try and say we had to have a landlords mortgage etc. Currently we are on a 2.49% tracker for 2 years - bargain. Wish I could bring enough money out to buy one here at those rates. Good luck.
