Bones vs. Additions: How to Evaluate an STR Property Like a Pro
You find a listing on Zillow. Three bedrooms, decent neighborhood, right price range. But can it actually compete with the top Airbnb earners in that market?
The answer depends almost entirely on one thing: the bones.
What "Bones" Means in Practice
Bones are the structural, unchangeable characteristics of a property:
- Ceiling height. Vaulted wood ceilings create a feeling no amount of staging can replicate. You can't add ceiling height after purchase.
- Room sizes. A master bedroom that fits a king bed and a sitting area is not the same as one that barely fits a queen.
- Floor plan and layout. Is the kitchen open to the living room? Does the home have two living spaces? Layout drives guest experience.
- Window placement and natural light. Oversized windows facing a mountain view can be the single biggest revenue driver in a market.
- Outdoor structure. Decks, patios, lot size, yard grading. You can furnish a deck, but you can't build one for the cost of a hot tub.
- Views. The ultimate unchangeable factor. A property overlooking a river will outperform one facing a neighbor's fence. Every time.
When you're scrolling Zillow, you're buying bones. Everything else is your job.
Additions: Your Competitive Edge
Additions are the features you add after purchase to increase revenue: hot tubs, game room equipment, fire pits, outdoor furniture, interior design, professional photos.
Here's why the distinction matters: when you study top-performing listings, many of them share the same additions. Any investor can buy a hot tub. What they can't copy is your property's bones. The bones determine your baseline. The additions determine how far above that baseline you can push.

The Practical Impact on Your Purchase Decision
Say you're looking at two properties in the same market, same price range.
Property A has high ceilings, a large open floor plan, a wrap-around deck, and a view of the river. The current listing has basic furniture and no amenities.
Property B has standard 8-foot ceilings, a smaller layout, no deck, and no view. But the Airbnb photos show a beautifully staged interior, a hot tub, and a game room.
Which one should you buy?
Property A. Without hesitation.
Property B looks better right now because the owner invested in additions. But you can do the same thing to Property A. And when you do, you'll have superior bones underneath those additions. You can't out-stage a river view. You can't out-furnish a vaulted ceiling with floor-to-ceiling windows.
The profit map shows where top performers cluster geographically. Location is a bone: you either have it or you don't.
The Game Room Test
Two properties both have "game rooms." One has a large, dedicated space with a pool table, arcade games, and room to move around. The other has a converted hallway that fits a foosball table and not much else.
On paper, both have game rooms. In reality, they're not comparable. The first property's game room is a bone: the room size and layout support a real entertainment space. The second is an addition forced into inadequate bones. Guests notice, and it shows up in reviews and repeat bookings.
Revenue Range by Bedrooms reveals how property size (a bone) drives income potential. The spread between top and average performers tells you how much the bones matter.
When you look at a property, ask two questions: Can these bones compete with the top earners in this market? And if I add the right amenities and design, can I push this property to the top of the revenue range?
If the answer to both is yes, you've found your deal.
