Onboarding a listing splits into things the property needs and things your business needs, and those get paid by different people.
The property side belongs to the owner. Professional photos for a three-bedroom typically run a few hundred dollars and are the single highest-return item on the list. Then linens at two or three sets per bed so a turnover never waits on laundry, towels at the same ratio, a full kitchen inventory, a coffee setup, a smart lock, a noise monitor if the neighbors are close, and a first restock of consumables. On a house that was somebody's home rather than a rental, add whatever it takes to make it feel like a rental instead of an estate, which usually means removing personal items and buying a few pieces that photograph well. A realistic range for that whole package on a three-bedroom is one to three thousand dollars, plus the smart lock and photos.
Your side is the software and the labor. Channel manager or property management system, dynamic pricing tool, and your time writing the listing, building the message templates, and setting house rules. Twenty to forty hours on a first listing is normal and none of it is billable.
The item people skip and regret is the permit. Many cities require a short-term rental registration before the first night, some cap the number issued, and rules differ by city and state, so check the actual ordinance for her address before anyone buys towels. Also decide now who owns the linens. If she does, they walk when she leaves. If you do, you have a claim on them, and that matters when the relationship ends.
