Londonderry is one of the largest towns in New Hampshire, positioned along I-93 south of Manchester. The town's growth has been driven by the highway corridor and the Manchester-Boston Regional Airport, which sits partly in Londonderry. The housing stock is predominantly single-family homes from the post-war era through recent construction, with commercial development along the highway.
For property professionals, Londonderry is a large, accessible suburban market with airport noise considerations for some properties, significant commercial property, and a housing stock that is newer than many New England communities.
