I'll try my best to keep this brief 
We bought our 2 bed house 5 years ago (£174,000)
Has recently been valued at (£180,000)
We still owe £150,000 on the mortgage and our 5 year plan is to pay off another £30k so in 5 years will have capital of £60k
We got our first mortgage based on our joint full time salary but I have since gone part time after having my son.
My DH income is £38k and mine is now £15k
What sort of figure are we looking at being able to borrow.
(I don't need it to be exact as its a 5 year plan, I just don't want to get my heart set on a type of house for the next 5 years to only find out we can get anywhere near it)
TIA
