Mortgage lending is asset-backed lending. If they approve you for a 300k mortgage and you buy a 250k house with a 300k loan then the risk to the lender is much greater than if you buy a 300k house or a 350k house. For 2 reasons: (1) because you have no equity in the house, you are more likely to hand in your keys if you lose your job or cannot make the repayments fro whatever reason and (2) if you do lose your job the bank has an asset worth less than the loan outstanding and so cannot recover the full debt with a sale. This happened all over the place in the UK in the early 1990's.
