I have actually done this before - when me and my ex split I sold one house, split the equity and bought a new smaller one for me.
I now have an almost 2 year old and a husband and we need to try and get a slightly bigger house in a slightly naicer area (near better schools, I just found out the school near where we are banned parents from the schoolyard after several of them ended up fighting eachother and throwing bikes around!).
I have about £50,000 equity IF I can sell the house for what I bought it for; I may lose about £10,000 judging by other houses for sale in my street so I think reasonably we will have £40,000.
We would also need to borrow maybe another £50,000 (taking mortgage up to around £140,000) to get a house in the place we want to be.
So far, does this all sound ok. We're lucky right? So why does it seem so scary?
Can I go and talk to my mortgage provider and basically sell my house (If I can) then transfer the mortgage I have to a new property + add a bit. Is that how it works out?
Sorry if this has been a bit of a ramble, I just need re-assurance that this sounds doable and not pie-in-the-sky.
