This is a semi-hypothetical question about a position we might be in in the future. I've made up the amounts just for easiness.
Can a bank loan you more than you need for your mortgage if it's still less than the value of the house?
So say we were going to buy a house that needs fixing up but has been valued at 200k but the owners were willing to sell it to us for £100k. Could we get a mortgage for £120k (so effectively 60% ltv) and use the remaining £20k for renovations etc?
