Swapping Chaos for Complete Control
Managing HMOs is rarely straightforward.
Unlike single-let properties, every HMO has multiple tenants, individual tenancies, shared spaces, ongoing maintenance, compliance requirements and constant communication. Keeping everything organised can quickly become the biggest challenge.
Outgrowing Disconnected Systems
As Sentinel’s portfolio expanded, the team found themselves juggling tenant messages, maintenance requests, tenancy information, compliance documents, contractor access and landlord updates across multiple platforms.
WhatsApp. Email. Spreadsheets. Calendars.
None of those tools were difficult to use individually, but together they created unnecessary complexity.
Sentinel has always been committed to running a transparent, organised agency that treats landlords and tenants fairly. But as the business grew, it became clear that maintaining those high standards required new and improved systems.
“The stress wasn’t just the workload. It was the worry that something could be missed. You can’t really run a proper HMO management agency on group chats and hope things turn out okay.”

Why They Chose COHO
The turning point came when the team realised they needed a single place to manage their entire property management operation.
Tenant WhatsApp groups had become a necessary part of communicating with residents because response rates were high, but they also created a major operational problem
Managing an HMO is fundamentally different from managing a traditional buy-to-let. Every property involves multiple rooms, multiple tenants, shared facilities, recurring compliance tasks and several issues happening simultaneously.
Sentinel needed software that was designed for that reality.
“I detest tenant WhatsApp groups, but they felt like a necessary evil because tenants are far more responsive there. The major limitation is accurately tracking maintenance and access issues.”

One Place to Manage Everything
After implementing COHO’s software, the biggest change was visibility.
The team could finally see everything relating to a property, room or tenancy in one place. Repairs, documents, tenancy details, communication and outstanding actions were connected, making day-to-day management far easier to follow.
Instead of searching across different systems, everyone worked from the same operational hub. Day-to-day management felt calmer, more organised and much easier to keep on top of.
Better Communication for Everyone
COHO transformed how the team communicated with tenants.
Residents had a purpose built way to report issues, while the Sentinel team had a clear process for managing requests, assigning actions and keeping track of progress.
Perhaps the biggest milestone?
For Sentinel, good property management isn’t simply about fixing problems quickly. It’s about always knowing what’s happening, who’s responsible and what needs to happen next.
COHO gives the team the visibility to do exactly that.
“We’re happy to report that tenant WhatsApp groups are gone from our business since using COHO.”

Building a Stronger Foundation for Growth
Sentinel describes COHO as an operational hub rather than simply property management software. It doesn’t replace experience, judgement or strong customer service – it gives the business the structure needed to deliver those things consistently as it grows.
“COHO helped us move from managing information in different places to having one clear operational hub. For an HMO-focused agency like Sentinel, that visibility is invaluable. It helps us stay organised, find tenants faster, communicate better and manage compliance properly.”
