Add-on revenue is real, and it is more constrained than owners are usually told. Extras are sold on top of a booking that already exists, so they are margin rather than rate - but the menu is not a catalog decision. It is set by what the building physically is and what the calendar allows, and at most properties a generic upsell list is mostly unofferable. Simple Lyfe Stays manages 44 doors across Newaygo, Lake, Mason, Oceana, Mecosta, Muskegon and Ottawa counties, and no two of them carry the same menu.
What can you actually charge extra for at a short-term rental?
Extras fall into four families. Supplies are consumables staged before arrival: firewood, a s'mores kit, a propane swap, bug spray in July. Food and welcome items are baskets, breakfast packs and first-morning groceries. Timing upgrades are an earlier check-in or a later checkout, sold as a service with no goods behind them. Service add-ons are the labor items - a mid-stay clean, a fire pit laid and ready to light, a linen refresh partway through a long booking.
Guests buy these between booking and arrival, while they are still planning. Once they are in the house, the window is closed.
Why don't standard upsell lists work at most properties?
Because every item on the list is gated by a physical fact about the property, and the gate fails quietly. Firewood and a s'mores kit need a fire pit. A water-toy rental needs water access - and needs the property to not already include the gear. Pickerel Lake Waterfront Cottage in Newaygo County, three bedrooms and one bath sleeping eight, comes with two adult kayaks, a child's kayak and two paddleboards. Offering a kayak rental there is not a sale - it tells the guest you have not read your own listing.
A pet welcome kit needs the property to take pets at all. Dragon House in White Cloud, three bedrooms and two baths sleeping eight, allows no pets of any kind, so that whole category is dead there no matter how well it converts elsewhere.
We learned this the expensive way. In April 2026 we recommended adding kayaks to a lake house we manage that already had four of them sitting in the yard. The cause was boring and instructive: our booking software returns door codes and operational notes, not a full amenity list, so anything read straight out of the system has holes in it - and a gap looks exactly like an absence.
What came out of it is a hand-maintained amenity file for every home we manage, verified against the live listing, with a "what this property does not have" section on every entry. Nothing reaches a guest until it clears that file. It is unglamorous, and it is the difference between an extra that reads as service and one that reads as a form letter.
Which add-ons have the best margin, and why can't you always sell them?
Timing upgrades. An earlier check-in or a later checkout costs nothing to deliver - no goods, no shopping, no drive - so nearly the entire price is margin. They are also the item you most often cannot sell.
The constraint is the turnover. When one guest checks out in the morning and the next arrives that afternoon, the whole cleaning window is a few hours with no slack at either end, and a late checkout is unavailable at any price. The highest-margin line on the menu is the one the calendar decides, not the owner.
Does the length of the stay limit what you can sell?
Yes, and it is the constraint owners underestimate. A mid-stay clean only makes sense on a long booking - a week, not a weekend. Across our portfolio the average stay runs under four nights, so on most reservations that item never appears at all.
Delivered goods carry their own gate. Anything a cleaner stages has to be ordered far enough ahead to ride the turnover - realistically a couple of days out. A guest who books Thursday for Friday is outside the window for everything physical.
What does delivering an extra actually cost in rural Michigan?
A drive. This is the part missing from national write-ups on rental extras, because it is a function of the map rather than the product. Our doors sit across seven counties, field runs start from fixed origins, and anything hand-delivered carries round-trip mileage that has to be priced into the offer. The same basket costs meaningfully more at a door forty minutes out than at one ten minutes away.
So the extras that survive are the ones a cleaner can stage during a turnover she is already driving to, or that a guest can be pointed toward locally. An add-on that needs a special trip has to carry the trip.
Is add-on revenue worth building?
It is worth building, and it is not a substitute for getting the rate and the occupancy right. Extras are a margin layer on a booking you already have; they do not fill an empty February. An owner with a pricing problem who spends the winter designing welcome baskets has solved the smaller problem.
Where they earn their keep is the review and the rebooking. A guest who walks into a stocked fire pit on a cold Friday remembers the house, and repeat guests are the cheapest bookings in the business. Build the menu from the property outward, never from a catalog inward.
Simple Lyfe Stays manages short-term rentals across western Michigan, and every property we take on gets a verified amenity record before a single offer reaches a guest.
