Explanation

Hire purchase allows buying expensive items through installments. Buyer pays deposit, then regular payments including interest. Ownership transfers only after final payment. Seller can repossess if payments default.

Advantages for buyer: afford expensive items (vehicles, appliances), use while paying. Disadvantages: total cost higher than cash price (interest), risk of repossession, item may depreciate faster than paid.

Differs from credit sale (ownership transfers immediately) and leasing (no ownership transfer). Hire purchase regulations protect consumers from unfair terms. Read contracts carefully before signing.
