One piece here is that yes you can potentially find buyers that will have a premium for successful track record + even furnishings, listings, review - but important to remember that there won't be a premium assessed by the lender in almost all situations if the buyer is using financing to acquire - their loan will be based on the pure real estate value even if they are paying more - just a tip to keep clarified so no surprises that can throw off deals
