An Investment Subscription Agreement (ISA) is a legal document that outlines the terms and conditions of an investor’s participation in a real estate or other investment opportunity. It specifies the rights and obligations of both the investor and the company, and should be approved by both parties before any money changes hands. The agreement should include details such as the amount and type of investment, the length of the investment period, procedures for certificates or other proof of investments, and protections for the investor—such as termination clauses or dispute resolution protocols. ISAs are essential for protecting your interests as an investor and foster trust between you and the company you’re partnering with.
