How the binder works
01
Work the number
Every calculator funds the reserves before it prints a result, so a unit that looks positive here is positive with a roof fund behind it.
02
Print the paper
Notices, receipts, ledgers and inspection sheets that fill in on screen and print on one page. Nothing to sign up for and nothing stored.
03
Check the rule
Every figure, cap and deadline on this site carries the statute it came from and the date it was read. When it is not verifiable, it is not stated.
Four sections
Deposits
Deposits & Move-Out
Taking a deposit, holding it where the statute says, deducting only what you can prove, and getting the itemised statement out before the clock runs down.
