I don't think is common practise in the U.K, but I asked around and lots of people told me it is more common that the larger agencies ask for it, plus it was for an apartment in a very competitive development so I feel like it might have been a forcing function to reduce the amount of applicants but that is speculation on my part.
A potential employer once also wanted statements - I think 6 months' worth, and I did the same. HR pushed back but legal backed them down rather quickly. I think these people ask because most just comply without question.
WTF.
That's a crazy practice. Paystub maybe, but bank statements? My gosh.
Unrelated rant but the reason I've been looking is my current landlord has taken over 35 days to send me a renewal contract. Go figure that 10 minutes after texting him I'm going through the credit check for a new apartment he sends me the updated document.
Before I got my place there were 3 other apartments in the same complex I verbally agreed to and then agent called back to say it had been taken. Not sure if you've rented in likes of London, NY or SF before but the competition can be intense.
Look it sucks that I had to do that, in an ideal world we could have done what you said, but I valued getting the place over my reservations of handing over bank statements.
You won't.
Many companies - utilities, landlords, hospitals, and so on - simply won't report anything unless it is negative. The negatives are usually sending something to in-house collections, a collection agency, or filing a civil suit to get the money.
Loans, in general, will report. This includes credit cards. Some of the buy here/pay here places won't report, though, so you get no help on your credit.
[1] What I mean by "live within your means" is to simply do things like pay cash for a used car, rent an affordable place, and simply pay your bills on time.
In the US, I don't believe any credit agency has insight into my personal bank accounts re size (I think?) or when things are paid to whom they are paid or the like (pretty sure about this). they know about my debts, but unless the landlord puts me into collection, I ca't imagine a reason for my rent appearing on the report (it's been a while since I looked at one, but dont remember seeing them)
