Mortgages are protected You will not lose your tracker rate, even if your mortgage is eventually sold by Ulster Bank to another institution, such as a fund. And if you have a fixed-term mortgage that rate will be honoured until the term is up. Ulster Bank tracker mortgage customers should do nothing. If you switch lender you lose the tracker. Whoever buys the UB tracker mortgage book will have to honour the tracker rate. Holders of non-tracker mortgages should consider switching, especially if they have a mature mortgage with equity built up in your home. If a fund buys your mortgage the new owner and the servicer of the mortgage will be subject to regulatory rules.
