Obtain a free home purchase or sale agreement form through sites such as LawDepot.com, RocketLawyer.com, Entrepreneur.com and AllLaw.com, as of 2015. Each site contains different versions of real estate purchase forms compatible with residential sales, though some may require special customizations to comply with various state laws.
LawDepot.com allows you to create a custom real estate purchase form by first choosing the state of the sale. The site then customizes the form to include all the relevant details according to the property sale laws of that state, asking you questions and populating the form with your responses.
RocketLawyer.com offers a similar service that also includes special options to ensure state law compliance. After completing the form, you may share it with other parties digitally, or download the form and print it out yourself. You can also sign it electronically to make it a legally binding contract.
Entrepreneur.com offers a free downloadable PDF real estate purchase form with blank spaces where you can write in the relevant aspects of the sale, such as the address of the property, the names of the buying and selling parties, and the date on which the sale goes into effect.
AllLaw.com also presents a free basic real estate purchase form, though you need to physically copy the contents of the form into another document in order to put the form into use.
