What we're comparing and why

If you're managing multiple properties, you face more than extra keys and calendars — you have scaling admin, compliance, maintenance workflows and cashflow complexity. This article compares two common approaches: using property management software and DIY tools as a self-managing landlord, versus outsourcing to a letting agent and paying letting agent fees. The goal is to help you choose the route that keeps control, reduces risk and suits the size and style of your portfolio.

Managing multiple properties: evaluation criteria

We'll judge each option by practical criteria that matter when you have several homes:

Cost: both direct fees and hidden admin time costs.

Control: how much autonomy you keep over tenants, maintenance and finances.

Scalability: how well the approach handles adding properties.

Compliance & risk: meeting safety checks, legal notices and record-keeping.

Tenant experience: responsiveness and professionalism that affects retention.

Time commitment: how many hours per week you’ll realistically need.

These criteria reflect what landlords juggling multiple properties tell us matters most.

DIY tools and property management software — detailed analysis

What it is

Using a mix of property management software, spreadsheets, marketplaces and task apps — or an integrated platform — to run listings, bookings, tenant screening, rent collection, maintenance tracking and accounts yourself.

Strengths

Cost-effective at scale: subscription or per-feature costs are often far lower than recurring letting agent fees.

Full control: decide vetting standards, contractor choice and whether to prioritise rental yield or convenience.

Transparency: your data, finances and tenant history are visible and exportable.

Automation: rent reminders, tenancy renewals and basic communications can be automated to reduce time.

Weaknesses

Time requirement: even with automation, someone has to handle exceptions, repairs and disputes.

Learning curve: integrating software, setting up workflows and staying on top of regulations takes effort.

Responsibility: compliance (EICR, gas safety, EPC, Right to Rent), deposit disputes and eviction steps remain your job — errors can be costly.

Good for

Landlords who are tech-literate, value control and want to minimise ongoing fees.

Portfolios growing beyond one property where agent commissions multiply.

Letting agents — detailed analysis

What it is

Handing day-to-day management, marketing, tenant liaison, repairs coordination and often compliance tasks to a third-party firm in return for letting agent fees and management commissions.

Strengths

Time saving: agents handle tenant calls, maintenance and legal notices.

Local expertise: high-street or regional agents know local markets and contractors.

Turnkey service: useful if you prefer a hands-off investment.

Weaknesses

Cost: management fees (commonly 8–15% of rent) add up across several properties and can erode yields.

Less control: agents use their contractors, set communication tone and make discretionary decisions.

Variable quality: not all agents deliver consistently; switching can be disruptive.

Good for

Landlords who do not have time or capacity to manage tenants and repairs, or who hold properties in far-flung locations they cannot visit.

Side-by-side comparison summary

Cost: DIY software typically wins once you have 2–3 properties; agent fees become disproportionately expensive as you scale.

Control: DIY wins — you set standards and retain tenant relationships.

Scalability: modern property management software scales well; agent scalability depends on their portfolio and service level.

Compliance & risk: agents often reduce compliance workload but you remain legally responsible; software helps with reminders and records but won’t fix a faulty gas boiler.

Time: agents save time day-to-day; DIY requires an initial setup and ongoing involvement.

When to choose each option

Choose DIY tools and software if:

You want to be a self-managing landlord and keep control of tenant selection and contractors.

Your portfolio is growing and you want to reduce ongoing fees.

You’re comfortable using online systems or willing to invest a few days to set them up.

Choose a letting agent if:

You have little time and prefer a hands-off income stream.

Properties are remote from where you live and you need local representation.

You need guaranteed, immediate full-service cover and are willing to accept the cost.

Hybrid approach

Many landlords use a hybrid: they manage core processes themselves using software, but outsource occasional tasks (e.g., urgent repairs or viewings) to local agents or contractors. This can deliver the best balance of control and convenience.

Practical steps to scale as a self-managing landlord

Centralise records: contracts, safety certificates, EICRs and EPCs in one platform.

Automate communication: set templates and rent reminders to reduce churn.

Use a vetted contractor network for faster repairs.

Track finances: bank feeds and reporting for tax and cashflow.

Review after each tenancy and refine processes.

A note on tools and a practical alternative

If you decide DIY is the right path, aim for a platform that bundles tenant messaging, maintenance triage, compliance reminders and accounts — that’s where you gain real time savings without losing control. Abodient is built for landlords who want to remain self-managing landlords: it handles the heavy admin (tenant messages, maintenance coordination, compliance reminders, paperwork and finances) while you keep decision-making and savings of not using a full-management agent.

FAQ

Q: How many properties before DIY tools make financial sense?

A: Often after 2–3 lets DIY tools offset letting agent fees, but it depends on your time value and how much admin you’d otherwise outsource.

Q: Can property management software handle legal compliance?

A: Software helps with reminders, document storage and standard templates, but you remain legally responsible for certificates and statutory duties.

Q: Are there hybrid models worth considering?

A: Yes — many landlords self-manage day-to-day with software and use local contractors or pay-for-service agents for specific tasks like viewings or emergency repairs.

Q: What’s the biggest hidden cost of using an agent?

A: Besides commissions, lower net rental yield from long-term contracts, unexplained contractor mark-ups, and the loss of data access can hurt returns.

Q: How do I maintain tenant experience if I self-manage?

A: Be responsive, use clear communication templates, provide a reliable repairs pathway and keep up with compliance — software automations help maintain standards at scale.

Conclusion

If you’re serious about managing multiple properties, modern DIY tools and property management software give you control, transparency and better economics as you grow. Letting agents buy time and convenience at a price. The right choice depends on how much time you can commit, how much control you want and whether you prioritise cost or convenience. For many landlords the smart path is to be a tech-enabled self-managing landlord, with selective outsourcing for tasks that require local boots-on-the-ground.
