When we BUY a camper, we ask the seller to arrange for a Notary and have a Sales agreement prepared on their state form (if out of state), or a DMV/Tag Notary in the same state.
We ask if there is a lien. If so, we ask if they have spoken with their bank and made arrangements to pay it off and provide a lien release or clear title that day. If it's a bank and all is notarized there, not a real problem waiting 7-10 days for the lien release letter.
BUT...you have to consider how the buyer will get it home? Will they bring a plate they transfer, get a new plate, or some kind of temporary tag? (not all places do this).
We bring 80% in Bank certified check and the balance in cash, depending on the final price.
Legitimate buyers should be prepared to spend a few hours on the transaction, transfers, inspections, banks, etc. It make a long day, but then all the business is handled and done.
We'll be selling our hybrid very shortly, but I am going to seal the roof, service the wheel bearings, check all the brakes and lights, clean everything and take care of any repairs I might find need done.
Campers in top condition are worth more to buyers (at least to us). Having all the running gear in serviced condition is important, too- especially for those driving a good distance. The last thing they want is to have a trailer breakdown on the way home :E
