Too easy rental approval — should I be worried?

Just got an offer for an older apartment and I’m about to sign the lease. I already viewed the unit with the building manager and everything seemed legit.

What’s throwing me off is how easy the application process was — they only asked for my application form and 2 pieces of ID. No proof of income, no pay stubs.(just wrote it on the form)

The manager said my employer is his firend, so skipped credit check as well.

The rent is relatively cheap, and the company is Linwood Property Management Ltd.

Is this normal for smaller/older buildings, or are there any red flags I should watch out for before signing and sending the deposit?
