We had to move from our old place and rent out our home about a year ago, as my husband's work location changed and the commute wasn't sustainable. We got a consent to let from our lender as the plan was to move back in a couple of years once his current contract came up for renewal. Along the way, about 9 months ago, we switched to a fixed rate mortgage with the same lender, while still on consent to let. We're renting in our new town. Our house in the old place gets a rent that easily covers the mortgage payment. Our original consent to let is valid for about 15 months from now (until Valentine's Day 2023 :)).
Now, we're considering buying a house in our new area as our rent is pretty high and we'd rather be using that kind of money to build equity in a property. We will probably still move back to our old place in a couple of years (and rent out the house we're considering buying here).
If we were to buy this second house while on consent to let, would lenders see that as a 'permanent' move?
If yes, what would happen to our consent at that point? Would we need to pay back the CTL mortgage and get stung by early repayment charges (as we're on a fixed rate)?
