 The Ontario Landowners Association also promotes the use of letters patent as a tool to aid in the protection of private property rights.

Forsalebyowner.com is the United States largest "by owner" real estate website.
 It provides a real estate advertising and information service that charges a flat fee to property owners who advertise their property on the company’s Website.
 It created a business model that competed directly with traditional real estate firms, connecting buyers and sellers without the use of brokers.
 Property sellers devise and customize the content and format of their advertisement.
 ForSaleByOwner.com then charged to the owners a listing fee that is directly proportional to the length of the advertisement and the period of time it appears on its Web site.
 For an additional fee, property owners can have also list their properties on the MLS with a real estate agent affiliated with ForSaleByOwner.com.
 Interested buyers can use the service to search listed properties for free.
 However, ForSaleByOwner.com does not represent or negotiate on behalf of either the seller or the buyer.
 On its Website, a disclaimer clearly states that it is not a real estate agent and is legally prohibited from taking part in the actual sales transaction.
A business improvement district (BID) is a defined area within which businesses are required to pay an additional tax (or levy) in order to fund projects within the district's boundaries.
 The BID is often funded primarily through the levy but can also draw on other public and private funding streams.
 BIDs may go by other names, such as business improvement area (BIA), business revitalization zone (BRZ), community improvement district (CID), special services area (SSA), or special improvement district (SID).
 These districts typically fund services which are perceived by some businesses as being inadequately performed by government with its existing tax revenues, such as cleaning streets, providing security, making capital improvements, construction of pedestrian and streetscape enhancements, and marketing the area.
 The services provided by BIDs are supplemental to those already provided by the municipality.
 The revenue derives from a tax assessment on commercial property owners, and in some cases, residential property owners.
Powder Horn Mountain (PMH) is a gated residential/resort community in Triplett, Watauga County, North Carolina, located in the Blue Ridge Mountains.
 The project was founded by developer Bob Horne, and included a golf course, riding stables and trails in nearby Wilkes County, but after undergoing bankruptcy and foreclosure it was divided and sold separately.
 A group of property owners founded a partnership called the Laurel Creek Group, purchased the homes from foreclosure, and created the Powder Horn Mountain Property Owners Association.
 The group then deeded the common property to the homeowners association.
The Preserve at Sharp Mountain (also called The Sharp Mountain Preserve) is a nature-based community located near Jasper, Georgia in Pickens County.
 It is one of three mountain communities in Pickens County, and the only one dedicated to maintaining its natural amenities.
 There are 12 mi of paved roads running through the community, but the population density is intentionally low (approximately 300 lots over 1600 acre ranging in size from a minimum of 3 acre to a maximum of 37 acres.)
 The Preserve at Sharp Mountain was named the "Best Community for Outdoor Lovers" by Pinnacle Living magazine, Unlike many planned communities, the Preserve at Sharp Mountain does not have swimming pools and tennis courts with club houses or golf courses.
 Instead, the Preserve at Sharp Mountain offers many acres of green space, hiking and nature trails, a nature pavilion, waterfalls, a bird sanctuary, a butterfly garden and various nature parks.
 The community is gated to restrict use of its 12 mi of privately owned roads to those living in the community.
 The Preserve at Sharp Mountain was developed by Four Seasons originally, which later became Naterra Land.
 Naterra's stated goal in all of its projects is "to better connect people with nature."
 Naterra Land sold out all of its inventory in the Preserve, and control of the community is now governed by a Property Owners' Association (POA).
 In 2011, the Preserve Association switched from being an HOA (Home Owners' Association) to being a POA (Property Owners' Association), each being viewed differently under Georgia law.
 In 2008 the Preserve became a recognized member of the national Firewise communities program and is one of the 13 in Georgia.
People of the State of California v. Federal Housing Finance Agency was a California state case in which several California-based plaintiffs filed suit against the Federal Housing Finance Agency (FHFA) for creating a lending rule that impeded the Property Assessed Clean Energy (PACE) program, a program in which property owners repay energy-related property improvements gradually over time (typically 15–20 years) as an addition to their property tax.
