Just sold our house and we are in rented.
Have found ideal house, needs a bit of work but it is 20% over our budget. It is possibly 10% over priced and it does need a bit of work.
But in any event we cannot afford to go over 80% of the asking price. That is our maximun budget.
We have mortgage finance in place plus large cash deposit and can move to their timescale.
Being realistic we will probably be rejected bbut want to try as that way it will give me ssome closure and I can move on 
What is the best approach?
