What Makes This Different
Every other tool audits
your listing.
Summit Stay Group audits your entire revenue architecture. The gap between what you earn and what you should earn isn't usually in your photos or your title. It's in your pricing logic, your calendar gaps, your channel mix, your cleaning fee ratio, your review velocity.

Most operators never look at these things together. We built a system that does — automatically — because Harvy looked at them every single day for 9 months and grew a portfolio by 38%.
What Listing Tools Give You
Title score. Photo feedback. Amenity checklist. Surface-level. Generic. The same advice for every property in every market.

Before — What We Inherited
Outdated photos — not representing the property quality
Weak listing titles — missing location keywords and USP
Spread across multiple booking platforms — diluting performance
Pricing not built around local demand — flat calendar all year
79 reviews across 2+ years of hosting
34% occupancy — below the Highland benchmark
After — The Summit Stay Methodology
Re-shot every property — photos rebuilt to convert
Rewrote every listing title — location, USP, search terms
Pulled off multiple platforms — focused single-channel strategy
Built pricing around area demand and booking behaviour
82 reviews in 9 months — 1.9× prior 2-year total
£190K+ annualised — 38% revenue growth, standards maintained
"In 2 years before me — 79 reviews. In 9 months with me — 82. Think about that. Revenue grew 38% without dropping standards once. 5 units. All sitting at 4.97–5.0★. All Guest Favourites."

5-Unit Portfolio · Scotland38% Revenue Growth4.97★ MaintainedGuest Favourite × 5Operations Background
I didn't come from consultancy. I came from the operations. Before founding Summit Stay Group, I managed a multi-unit STR portfolio from the inside — pricing decisions, calendar control, listing positioning and guest experience across every unit, every day. I grew revenue by 38% in 9 months without increasing overall occupancy, maintaining 4.97–5.0★ ratings throughout. The ten audit layers in this platform are the exact ten things I check on every property I work with. The benchmarks, the thresholds, the operator logic — that is what makes this unreplicable. This is not a SaaS dashboard. This is a consultant's methodology — automated.
