Do you already have an option agreement signed? If so, have your lawyer review the provisions of the agreement and explain it to your satisfaction.
I do not see enough information in your post to give a reasonable response. You may be giving away an equity share in your other property that is converted to cash when the property is sold. You may be giving a mortgage on your other property with periodic payment intervals, and release of lien is obtained when the final payment is made.
Have your attorney review the documents and advise you further.
