There are several forms of home ownership: single-family homes, multiple-family homes, condominiums and co-ops.
Single-family homes: One home per lot.
Multiple-family homes: Some buyers, particularly first-timers, start with multiple-family dwellings, so they’ll have rental income to help with their costs. Many mortgage plans, including VA and FHA loans, can be used for buildings with up to four units, if the buyer intends to occupy one of them.
Condominiums: With a condo, you own “from the plaster in.” You also own a certain percentage of the “common elements” – staircases, sidewalks, roofs, etc. Monthly charges pay your share of taxes and insurance on those elements, as well as repairs and maintenance. A homeowner’s association administers the development.
Co-ops: In some cities, cooperative apartments are common. With co-ops, you purchase shares in a corporation that owns the whole building, and you receive a lease to your own unit. A board of directors, comprised of owners and elected by owners, supervises the building management. Monthly charges include your share of an overall mortgage on the building.
