Porting a mortgage question!

Parisian

I currently own a flat with a residential mortgage, and I am planning to remortgage when my current deal comes to an end at the end of January. 

I am due to inherit a house in the next few months, and this will be mortgage free. The plan with that is to undertake some renovations that might take around a year (maybe more, unclear at this point) to complete.

Would I be technically (obviously lender dependent at the time) be able to port the mortgage from my flat, to my house with a much higher value at a later date? I would then be living in the house, and hoping to rent out the flat (not sell the flat, which is the part I'm not sure is compatible with porting). I was trying to see if this is a scenario a lender might be open to instead of remortgaging the flat to a buy to let product. 

I am probably not thinking of something important here, so any wisdom gratefully received!

No, you would have to sell the flat in mortgage Port situation

Yes as above, sell flat. Clear mortgage then re-mortgage the inherited house to renovate.

Take out a new mortgage on the house, use the proceeds to clear the mortgage on the flat. This wouldn’t be porting, so you need to look for a new mortgage deal on the flat without ERCs.
