Until very recently I worked in the mortgage dept of one of the UKs biggest banks. We would lend up to a maximum age of 75 (with a minimum mortgage term of 5yrs) and you could either self certify your earnings. pension/investments etc providing you had a min 20% deposit. Alternatively if you do have pension income that can be evidenced then you could borrow based on that up to a maximum 95%ltv. So, in a nutshell, providing you are 70 or under and have some sort of income and deposit you should be able to get a mortgage as easily as the next person.
