Lets make it so that when landlords give you that story at the end of your lease about why they have to keep your deposit, they have to show invoices and proof of works. People are paying for services that are never actually bought by the landlord.
Why is this important?
People get robbed by landlords everyday. "We need to clean this, we need to replace that" and they do none of it before the next person moves in and pays another deposit. You are paying for these services so they should have to prove that they actually spent the money doing them things and its not going into their pocket.
