It is better not to create the wholesale contract yourself. If you don’t know how to do this, use the help of a specialist. Consult with your attorney. You may use the help of the real estate agency if you want. However, if you feel that you know how to do it, you may use the template on the PDFLiner as an example and create the document from the very beginning. Fill the empty page with the sections you need. The benefit of this option is that you can include the information you need, including extra conditions. However, they have to match the local laws, and the other party has to agree to these conditions. Without the second signature on the template, it will be invalid.
