What does outsourcing a lettings back office actually cost?

Managed lettings back-office services are usually priced per managed property per month, sometimes as a share of management fee income, and occasionally per service. The honest answer to "what does it cost" is that the number only means something next to the fully-loaded cost of doing the same work in-house — which is not a salary, but a salary plus employer's National Insurance, pension contributions, holiday and sickness cover, recruitment, training, software licences and the cost of mistakes. Compare like with like and the decision usually becomes obvious in either direction.

How is a managed back office usually priced?

Three models dominate, and each behaves differently as you grow:

• Per property, per month. The most common and the easiest to forecast: a flat fee for each managed property. Cost scales linearly with the portfolio, so it is predictable and easy to build into your own fee structure.
• A share of management income. Priced as a percentage of the management fees you collect. It flexes with rent levels, which can suit a portfolio with unusual rent spreads, but it couples your supplier's income to your pricing rather than to the work done.
• Per service or per task. Client money handled separately from repairs, or a fee per inspection. Useful if you only want to hand over one function, but it can get expensive and hard to predict once volumes rise.

What sits inside the fee matters as much as the model. A price that covers the software but not the people doing the work is not comparable to one that covers both.

What actually drives the price?

Two providers can quote very differently for the same portfolio because these variables differ:

1. Which functions are included — client money and reconciliation, repairs and maintenance coordination, compliance tracking, periodic inspections, tenant and landlord communication, arrears chasing. Every function you add is work someone has to do.
2. Portfolio size and mix. More properties usually means a lower per-unit price. HMOs, student blocks and heavy-maintenance stock carry more work per door than newer single lets.
3. Whether software is included or extra. Some managed services run on your system; others include their own platform. If it is not included, the licence cost is yours on top.
4. Where the team sits. A UK-based team that understands tenancy law, deposit rules and compliance obligations costs more than an offshore call centre — and behaves very differently when something goes wrong.
5. Volume of exceptions. Arrears, disputes, complex works and difficult tenancies consume disproportionate time. Ask how those are handled and whether they are charged differently.
6. Onboarding and migration. Importing properties, tenancies, compliance dates and balances is real work. Ask whether it is included and how long a parallel run lasts.

What does the in-house alternative really cost?

This is where most comparisons go wrong: a property manager's salary is only part of the number. The fully-loaded cost includes:

• Employer's National Insurance on the salary.
• Pension contributions — auto-enrolment is a legal obligation, not an optional extra.
• Holiday, sickness and cover. Statutory holiday alone takes someone out for weeks a year, and the work does not pause while they are away.
• Recruitment and onboarding — advertising or agency fees, plus the months before a new hire is genuinely productive.
• Software and tools they need to do the job.
• Management time spent supervising, training and covering gaps.
• The cost of errors — a missed compliance date, a mis-posted receipt or an invalidated notice can cost far more than a month's salary, in remediation and in reputation.

Set that fully-loaded figure against a managed fee for the same functions and you are finally comparing like with like. The other half of the comparison is capacity: a single hire gives you one person's hours and one person's holiday risk, whereas a managed service is designed to absorb volume without you re-running the hiring process every time the portfolio grows. We work through that trade-off in detail in outsource vs hire a property manager.

Is it cheaper than hiring?

Sometimes, but that is the wrong question to stop at. Cost per property is only one axis; the others are capacity, continuity and risk:

• Capacity. Can you take on thirty more doors next quarter without a recruitment round?
• Continuity. What happens in August, or when someone resigns with a month's notice?
• Risk. Who is accountable for a lapsed certificate or a client-account discrepancy, and can they evidence it?

A managed service tends to win on capacity and continuity, and to price predictably as you scale. An in-house team can win where volumes are low and stable, or where the work is unusually bespoke. The honest answer depends on your portfolio — which is why any credible provider should quote against your actual numbers rather than a rate card.

What should you ask before signing?

Take this list to any provider, including us:

• Exactly which functions are included, and what is explicitly out of scope?
• Is the software included, or is it a separate licence?
• Is the team UK-based, and will we have named, consistent people?
• How is client money held — a ring-fenced, FSCS-protected client account, with Client Money Protection scheme membership? (See client money protection explained.)
• What does onboarding involve, how long does it take, and is there a parallel run?
• What are the notice terms, and what happens to our data if we leave?
• What is genuinely automated versus done manually — and who approves spend?
• How are exceptions handled — arrears, disputes, emergency works?

Frequently asked questions

Is a managed back office charged per property or as a percentage?

Both models exist. Per property per month is the most common and the most predictable to forecast; a percentage of management income flexes with rent levels. Ask which functions the fee covers before comparing two numbers.

Does the price include the software?

Not always — and this is the single biggest reason two quotes look different. A software-only licence does not include anyone doing the work; a managed service should cover both the platform and the people. Confirm which you are being quoted.

How much does it cost to run a lettings back office in-house?

More than the salary. Budget for employer's National Insurance, pension contributions, holiday and sickness cover, recruitment, training, software and supervision — plus the risk cost of a missed compliance date or a reconciliation error. That fully-loaded figure is the fair comparison.

Cost only tells you something useful when it is set against the work it replaces and the capacity it buys.
