This is probably a really stupid question and shows my ignorance but here we go....
We are just about to put our house on the market, it is valued at £320k and we have £150k equity in it. I called my mortgage provider as currently in a fixed deal that ends March 2021 as I wanted to work out how much they would potentially lend to us for our next property. They said to check their online affordability calculator to get a rough idea, which I did. I also checked a couple of other providers and their calculators came back that they would potentially lend us more.
My question is, if we were to find preferential rates with another provider could we port our existing mortgage to a new property and take out a second mortgage with a different provider to make up the difference? This will be our first time selling a property and buying another, we were first time buyers last time so it's all new!
