Message sellers, make offers, and agree on terms — all through our secure in-app messaging system. No need to share personal contact info until you're ready.

Step 3: Prepare the Transfer

Use our Form 4 guide to prepare all required documents and paperwork. Our state compliance checker ensures the transfer is legal in your jurisdiction.

Step 4: Complete & Review
