A New Hampshire sublease agreement allows you to rent out property you’re already renting to a new person (or “subtenant”). Based on your preferences, you can let this subtenant live on the part of the property (assuming you still want to live there) or sublet the entire property to them if you’re living elsewhere.
Remember that your subtenants must follow all the terms in the original lease while using your rental. Despite that, you’re still responsible for the property’s condition and making all rent payments on time and in full to the original landlord.
