I always ask for proof of funds before formally accepting an offer on behalf of a client. I usually do this after negotiations (unless i suspect something fishy).
It is simply to check affordability and make sure they are serious buyers before we take the property off the market.
Yes, I suppose the buyer could forge the Decision in Principle but you’d have to be a bit off a **** to do that. It costs nothing to get a DiP and if you have to forge one then you shouldn’t be making offers.
Also, not all agents are scum and/or parasites. Admittedly I know a hell of a lot who are and I think that historically the profession attracted a certain type of person but times are changing. You get bad eggs in every profession though.
My wife and I started doing this 5 years ago at 35 (after working in a completely different professions) and i can tell you now it’s a challenging career. Way way harder than i expected it to be. Long demanding hours – which is also part of being self employed and caring about your business and customers.
Ive also met a lot of amazing agents along the way. Its easy to be a bad agent but ask anyone who’s had a good experience with an agent that cares and fought for a good result and I am sure they will tell you they were worth the fee.
OP, feel free to DM me if you need any advice along the way. I’ll gladly help if i can. Good luck!
