Apartments for rent in New Hampshire, Maine and North Carolina.


For the safety and security of both our residents and managers, cash is not accepted. We do accept checks and money orders.

Current residents can also pay online with e-checks or credit cards by clicking Pay Rent Online. Keystone Management has partnered with RentPayment, the largest processor of multifamily rental payments. To use the online system, current residents will require their personalized resident ID or t-code. Please call the local management office to receive your t-code. Save on postage and choose to never be late or pay a late fee again. We highly encourage the free e-check option that is set up through your regular checking account. For rental payments, credit and debit cards have a $27.50 convenience fee for each transaction.

For applications, Keystone Management charges a $30.00 non-refundable processing fee. This processing fee can be paid with check or money order if completing the application in person. Alternatively, this processing fee can be paid with credit or debit card if completing the application online.
