The Installment Sale Agreement (Real Estate) is a crucial document in Philippine real estate transactions where buyers prefer or require payment through installments rather than a lump sum purchase. This agreement type is particularly common in residential and commercial property sales where buyers seek to acquire property through manageable periodic payments. The document must comply with the Maceda Law (RA 6552), which provides specific protections for buyers in installment sales, including grace periods and refund provisions. It needs to address all essential elements required under the Civil Code of the Philippines while incorporating specific terms about the property, payment schedule, interest rates, and conditions for title transfer. The agreement is typically used by property developers, real estate companies, and individual sellers who wish to offer flexible payment terms while protecting their interests in the property until full payment is received. It includes comprehensive provisions for default scenarios, property maintenance, taxes, and other obligations during the installment period.
