New Hampshire rule applied to your numbers
Maximum deposit
$2,000
Up to 1 month’s rent under New Hampshire law. A landlord cannot require a security deposit greater than one month's rent or $100, whichever is larger (RSA 540-A:6). The rule applies to covered residential landlords. Under RSA 540-A:5, a person who rents a single-family home and owns no other rental property, or who rents units in an owner-occupied building of five units or fewer, is not treated as a landlord for these deposit rules, except for any unit in that building rented to a person 60 years of age or older. In those exempt situations the statutory cap and other deposit protections do not apply.
Return deadline
30 days
30 days after the tenancy ends. Enter your move-out date for the exact deadline.

These are the New Hampshire figures applied to what you entered: a plain summary of the rule and the dates, not a determination that anyone did or did not comply.

If a deposit is wrongly kept
If the landlord keeps your deposit wrongfully, fails to return it on time, fails to pay owed interest, or fails to give the itemized statement, you can sue for twice the amount of the security deposit (RSA 540-A:7). A broader violation of RSA 540-A can also expose the landlord to actual damages or $1,000, whichever is greater, plus costs and reasonable attorney fees (RSA 540-A:4).
Interest on the deposit
A landlord who holds your deposit for one year or longer must pay you interest, calculated at the rate the bank pays on regular savings accounts where the deposit is held. If the landlord pools several tenants’ deposits in one trust account, the actual interest earned is paid out proportionally to each tenant. If the deposit is held less than a year, no interest is owed.

How New Hampshire security deposits work

New Hampshire caps a residential security deposit at the greater of one month’s rent or $100, so even on a very low rent a landlord can still ask for up to $100 (RSA 540-A:6). Your deposit stays your money: the landlord must hold it in trust at a New Hampshire bank or credit union, or post a bond with the town, and cannot mix it with personal funds. If the landlord holds the deposit for a year or longer, they owe you interest at the rate the bank pays on regular savings where it sits. After the tenancy ends, the landlord has 30 days to return the deposit with any interest, or to give you a written, itemized statement of the damages they are charging for, backed by receipts or estimates. If the landlord keeps your money wrongfully or misses these steps, you can sue for twice the deposit. One important exception: owner-occupied buildings with five or fewer units, and single-family rentals by an owner with no other rental property, are outside these rules unless the unit is rented to someone 60 or older.
