Quarter Homes is a real estate technology company that modernizes vacation home ownership through a fractional, co-ownership model. It aims to make owning a second home more accessible and affordable by allowing up to four parties to collectively purchase and own a property. Quarter Homes manages the entire lifecycle of the property, including all legal, financial, and property management complexities, to provide a seamless, hassle-free experience.
The company’s innovative model incorporates the Hedera blockchain network, which underpins its operational framework. For each property, a unique LLC is established, and the legal ownership interest is divided into fractions represented as non-fungible tokens (NFTs) on the Hedera Token Service (HTS). This provides each owner with a verifiable, digital proof of ownership.
Quarter Homes leverages the Hedera Consensus Service (HCS) to create a transparent and immutable log of all activities associated with the property. This includes governance, maintenance activities and scheduling, ensuring all parties have a trusted and shared view of the property's status and history.
