Hi I took my mortgage out interest only with Halifax, they will do 10years interest only. I’m treating the period as breathing space for 10 years to see how renting goes etc.
Halifax ok to deal with but you have to chase them. Initial work done in UK which helps. Spanish side takes an eternity if you are thinking of doing this start it soon but be very aware of all the fees etc. may have to pay more tax etc.
You also pay a premium rate for IO i’m paying 3.6ish think you can get repay deals around 3.3ish
Hope this helps GB
