A home reversion plan is a financial arrangement that allows homeowners, typically aged 55 and over, to sell a portion of their property in exchange for a lump sum or regular payments. In this plan, the homeowner retains the right to live in their home for the rest of their life, while the reversion company gains ownership of the agreed-upon share of the property. This type of plan can provide additional income for retirees, helping them cover living expenses or fund other needs. However, it is important to understand that the value of the home may decrease over time, affecting the final payout to the homeowner's estate after their passing.
