Good to know
- The landlord must give a signed receipt saying where the deposit is held (unless you paid by check) and tell you in writing to report needed repairs within 5 days of move-in.
- Deposits must be kept in trust at a New Hampshire bank, savings and loan or credit union, separate from the landlord's own money, or covered by a bond.
- Other allowed deductions include unpaid rent, lawful charges under the lease, and a tenant's share of real estate tax increases if the lease requires it.
- A lease clause waiving these rights is void.
Tips for landlords
- Do a written move-in inspection and have the tenant sign it. Take dated photos of every room, including inside appliances and closets.
- Collect the tenant's forwarding address in writing at move-out.
- Put the itemized list and the refund in the mail well before the deadline, and keep proof of mailing.
- Normal wear and tear (faded paint, light carpet wear, small nail holes) usually can't be charged. Damage beyond that can.
Tips for tenants
- Take your own dated photos and video on move-in day and move-out day.
- Give your landlord your forwarding address in writing, and keep a copy.
- If the deadline passes, send a written demand letter that cites the law above before going to small claims court.
