Property manager vs self-managing several flats – which to choose?

Among the people I know there are a dozen or so investors with portfolios of 3-10 flats let on a long-term basis. The yield in big cities? In theory 5-7% a year. But that’s the theory. In practice, how much actually ends up in your pocket comes down to how you manage the properties. And that’s where the age-old question pops up – hire a property manager or do it yourself? I’ve tried both models. Each has its strengths and its traps.

What does a rental property manager actually do?

A property manager takes on the entire rental management cycle. From finding a tenant to ending the tenancy. Screening candidates, paperwork, handover protocols, photographic documentation – all of that is lifted off the landlord’s shoulders. And honestly? With several units that’s a real relief, because the manager knows the regulations and knows how to react when things get out of the ordinary.

Day to day, the manager settles utilities, stays in touch with tenants, and coordinates repairs when something breaks. On top of that comes the whole formal and legal side – compliance with tenant protection regulations, energy performance certificates (mandatory since April 2023), and getting ready for the KSeF rollout. That’s quite a lot.

What exactly falls within a manager’s scope of service:

• Sourcing and vetting tenants
• Preparing tenancy agreements and addenda
• Settling utilities and operating charges
• Regular inspections of the unit’s technical condition
• Recovering overdue payments
• Photographic documentation when handing over and taking back the flat

Self-management – what you need to know and be able to do

Decided to handle everything yourself? You’ll need to get a grip on several areas of law. First and foremost – the types of agreement. A standard tenancy, an occasional lease and an institutional lease are three completely different beasts when it comes to the protection of each party. Notice periods are governed, among others, by Article 112 of the Civil Code – a term specified in months ends on the day matching, by date, the day on which the term began. It sounds dry, but in a dispute with a tenant this knowledge saves your skin.

The basic obligations? Keeping the unit in a usable condition throughout the entire tenancy, handing the tenant the energy performance certificate, and the handover protocol. Skipping these formalities costs money – the absence of an energy performance certificate carries a fine of up to 5000 zł. And taxes? A flat-rate tax on rental income applies. Planned changes in 2026 and the potential KSeF rollout mean you have to keep up with the regulations on an ongoing basis. There are no shortcuts.

Tip: When managing multiple units, it’s worth asking utility providers to shorten the billing periods (electricity, gas, internet). Where that isn’t possible – e.g. for water and heating – setting a monthly flat-rate for tenants or settling according to meter readings at the end of each month works well.

The cost of a manager vs the cost of self-management

Managers usually charge in one of two ways – a percentage of the rent (8-15%) or a fixed rate per unit. Let’s do the maths. Five flats, 12,000 zł of rent in total per month. The manager’s commission swallows between 960 and 1800 zł. Not exactly cheap. But the question is – how much is your time worth?

SaaS rental management systems offer “per unit” pricing plans – from 9.84 PLN on the basic tier, through 14.76 PLN on the advanced tier, up to 25.83 PLN per unit per month on the professional plan – which, with a small portfolio, amounts to a fraction of a manager’s cost.

The cost of self-management is usually underestimated. Because people only count the financial outlay. And what about time? Dealing with tenants, travelling, organising repairs, paperwork – all of that has real value. And then there’s the risk of legal mistakes. A poorly drafted agreement or a missed formal obligation can cost more than a year of a manager’s commission. From my experience, the break-even point for professional management appears at five or six units. That’s when self-management starts eating up a dozen or so hours a week and stops being fun.

SaaS tools – the third way between a manager and full self-reliance

Comprehensive SaaS systems offer utility billing, remote signing of agreements and KSeF integration. The “per unit” pricing model pays off up to around 5 flats; with 10 or more units it gets close, price-wise, to professional management. Their strong point is generating documents – agreements, addenda, protocols and invoices – directly from within the system.

These platforms fill the gap between doing everything yourself and handing your portfolio over to a manager. They automate the most tedious administrative work but leave you in control of the decisions. With a portfolio of up to five flats, the cost of the tool doesn’t exceed a few dozen zł a month. The cheapest option on the market, no two ways about it.

Tip: When choosing a SaaS tool, check first and foremost whether it supports generating occasional lease agreements with the full set of attachments, as well as candidate screening. These features are what set the individual platforms apart and can decide whether the system genuinely takes the load off you in the day-to-day running of your portfolio.

When to use a manager and when to go it alone – decision criteria

The location of the flats – that’s the very first factor I’d start with. All units in one city? Self-management is realistic even with a larger portfolio. But spread them across several metropolitan areas and suddenly the travel eats up all the savings you made on a manager. In that case it’s either a manager or a hybrid model with a SaaS tool.

The tenant profile matters too. Students generate high turnover – more frequent searches for tenants, new agreements, protocols every five minutes. Families? Stability and peace of mind. And then there’s your own availability. Working a full-time job? That’s a different situation than when property management is your main occupation. Broadly speaking – with two or three units self-management is fine, with five to ten it’s worth considering some support, and above ten a professional property manager becomes practically a necessity.

The most common mistakes when choosing a management model

I’ve seen it many times – landlords underestimate the time needed to handle several tenants at once. One breakdown, a late payment, a tenant change – and there goes your whole day. And what if several such events hit different units at the same time? Neglect, frustration, chaos. It could have been avoided by planning the management model in advance.

The second classic mistake – choosing a manager on price. Without checking the scope of services, without references from other landlords. The cheapest offer often means a slow response to breakdowns or zero legal support. Skipping handover protocols and photographic documentation can be costly too. No such documents = disputes over the deposit = a financial loss. Oh, and one more thing – landlords routinely forget to factor the cost of vacancies and tenant turnover into their yield calculations. The result? Expectations inflated by even a dozen or so percent.

Summary – how to make the right decision?

A manager saves time and minimises legal risk, but eats up 8-15% of the rent. Self-management maximises your profit – but it requires knowledge, availability and a tolerance for stress. There’s no one-size-fits-all answer. The optimal model depends on the scale of your portfolio, how scattered the flats are, and how much time you can realistically devote.

On the Polish market a hybrid approach is becoming increasingly popular – SaaS tools plus partial self-reliance. You keep control over your portfolio while automating the most tedious administrative work. My advice? Before you make the final decision, test the available rental management platforms. Most offer a free trial period and you’ll quickly see how many tasks can be automated without involving a manager.
