Hi there and a warm welcome to the forum
Taking your questions in the same order
1 There is no time limit on putting forward a variation to the terms of your IVA.
2 If your property is really excluded - please make sure that it is - then you will need the Supervisor's permission to remortgage.
3 There are plenty of lenders who will lend to people in IVAs, but you will be penalised for this in terms of interest rate and loan to value.
Glad you are finding the forum useful. We all do!
