How long does a landlord have to return a security deposit in Michigan?

In Michigan, the security deposit and an itemized statement of any deductions are generally due within 30 days of move-out (MCL 554.609). Missing the deadline can forfeit the right to withhold and expose the landlord to added damages. Confirm the current statute for your situation.

Do deductions have to be itemized?

Yes — in nearly every state a landlord must provide an itemized statement listing each deduction, not a vague lump sum. This generator lists each deduction on its own line with an amount and does the refund math.

Is the letter generator free?

Yes — free, no signup. It itemizes deductions, does the refund math, cites the state deadline, and can email the PDF so the timestamp documents timely delivery.

What the Michigan letter has to contain

Every deduction on its own line. Michigan requires an itemized statement rather than a lump sum (MCL 554.609).
The arithmetic, shown. Deposit held, each deduction, and the balance refunded or still owed — so nothing has to be taken on trust.
Where the refund went. The forwarding address you sent it to, and how.

Proving you sent it in time

The deadline is about when the letter left, and in a dispute that is the fact in question. Email gives you a timestamp for nothing; certified mail gives you a receipt. Either beats posting it second class and hoping. Whatever you use, keep the copy you sent — a Michigan deadline you met but cannot evidence is not much better than one you missed.

Working out what you can defensibly deduct is a separate job from writing the letter — that lives on the Michigan deduction page, which prorates each item by its remaining useful life.
