Hello,
I think there is a separate argument for a Homeloan and other types of personal loans.
With regards to a Homeloan, the home should have been purchased and the related debt repaid by retirement age (if there is ever to be home ownership, which is not essential btw) - if anything, the homeowners should be starting to think about possibly downsizing, perhaps releasing equity along the way etc.
Sure, we can get into a debate about equity release loans / reversionary loans, but thats not always the right approach and also, not what I would call a mainstream loan.
As for other loans, they should all be readily available to all borrowers, once in good health, capable of repaying the loan, having a good credit record etc. I would support the Banks being entitled to look for health records, or to have the borrower get a medical exam as a condition of advancing loans over a certain size for example, if this put their minds at ease. However, the Banks need to remember that expected average life expectancy is now into the 80s and getting longer, so telling someone at age 66 that they are too old to get a loan is wrong.
I can appreciate that the risk of complications regarding older people getting long term illnesses and perhaps passing away are issues that a Bank might not want to get caught up in, but there is always the option of pricing for these risks. Likewise, there are ways to reduce this risk, such as checking current health status, getting assignment of small life policies or perhaps certain types of serious illness policies and so on. One glove clearly does not fit all, but when there's a will there's a way.....
