Illustrative deposit example computed from the county median rent: one month of the Census two-bedroom median is $1,434; two months is $2,868. This is an example computed from the county median, not a legal cap or a survey of deposits. The calculations below use the one-month deposit of $1,434.

State legal maximum deposit in New Hampshire: Not more than one month's rent ($1,434 at the example rent) or $100, whichever is greater. Security deposit means all funds in excess of monthly rent transferred for any purpose. Quarterly (or less frequent) rent payment leases allowed, but deposit still cannot exceed one month's rent ($1,434 at the example rent) equivalent.

Total households in Merrimack County: 60,445.

Renter households: 16,019 (26.5% of all households).

Renters spending more than half their household income on rent: 4.5%. A delayed deposit refund can leave these households with less money for their next rent payment.
