Not all amenity investments are equal. A $12,000 hot tub can add $18,000/year in revenue. A $25,000 pool addition might add $4,000. Here's the data on what actually works.
The worst STR upgrade mistake isn't spending too little — it's spending significant money on the wrong things. Investors regularly drop $3,000 on statement artwork, $8,000 on designer kitchen appliances, and $1,500 on a smart refrigerator that plays YouTube, and then wonder why their ADR hasn't moved. Meanwhile, the $11,000 hot tub they skipped would have added $16,000 in annual revenue.
Amenity investment is one of the highest-leverage decisions in STR operations — but only when it's driven by data, not intuition. Here's the framework.
The calculation is straightforward: Annual Revenue Increase ÷ Upfront Cost × 100 = Annual ROI %. But that formula needs a few qualifications to be useful.
First, amenities affect two revenue variables, not one — ADR and occupancy. A hot tub might allow you to charge $25/night more (ADR impact) and also fill 8 shoulder-season nights you would have otherwise lost (occupancy impact). Both need to be modeled. Second, amenities have ongoing costs — maintenance, supplies, occasional replacement — that reduce the net return. A hot tub at $10,000 installation with $800/year in chemicals and maintenance generates a different 5-year ROI than the headline number suggests. Third, the payback period matters because amenities depreciate. An upgrade with a 6-year payback on an asset that needs replacing in 5 years doesn't pencil. An upgrade with a 14-month payback on a 10-year asset is exceptional.
These are the upgrades with consistently documented positive ROI across most STR markets. They are data-validated through review analysis, comp performance comparison, and PropertyIQ Amenity IQ assessments across hundreds of properties.

PropertyIQ's Amenity IQ section identifies the specific amenities present in the top-performing comparable listings in your market — and which gaps are costing you ADR and occupancy right now.

These are amenities that look premium but that guests consistently do not mention in positive reviews and do not pay higher rates for.
The most data-driven approach combines three sources:
Not all upgrades should happen at once. A sequenced approach — starting with highest-payback, lowest-risk investments — produces better cumulative returns than a single large upgrade spend.
A PropertyIQ report gives you the Amenity IQ comparison — showing what the top-performing comps in your market have, what they're charging for it, and where your investment budget will generate the highest return.

Do the comp analysis before you write the check. The data on what works in your specific market exists; the only question is whether you use it.
