Near the end of the 1900s many properties in Mainsville which once belonged to the first settlers were sold to the government Land Bank. After the properties were purchased, the homes and farms were usually demolished or simply left abandoned. Although many century-old structures were lost, several other buildings from the beginning of the settlement remain standing or occupied. Mainsville has no businesses in operation as of 2016, and consists mostly of residential properties and a few small farms. Newer houses have been periodically built within the community since the mid-1900s.
