AFAIK, agents do no vetting of clients.

Except that most agents don't want to waste time showing
people round a property unless they think they have a
reasonable chance of getting a commission, so they do
try and get an idea of whether they are serious buyers.

The estate agents round here will happily send anyone
details, but won't let you look round houses unless you have
sold your house and have a decision in principle on any
mortgage needed. I doubt they check these details of course,
so it doesn't stop people lying and pretending to be serious
buyers...
