Property Management Software Pricing Models Explained
The pricing model your software uses matters more than the headline price. We modelled the 3-year cost of per-unit, flat-fee, tiered, and freemium pricing across portfolios of 1, 5, 10, and 25 properties. The cheapest option at 3 properties becomes the most expensive at 15.

Editorial
The pricing model your property management software uses matters more than the headline price. A platform advertising £5 per month can cost three times more than one advertising £20 per month once you add a second, third, or tenth property. According to our 2026 UK pricing report, the difference between the cheapest and most expensive pricing model over three years exceeds £2,000 for a landlord with 10 properties — yet most comparison sites ignore this entirely, focusing on the starting price rather than the total cost of ownership.
This guide breaks down the four pricing models used by UK property management software in 2026: flat monthly fee, per-unit pricing, tiered pricing, and freemium. We modelled the cost of each model across portfolios of 1, 5, 10, and 25 properties, calculated the three-year total cost of ownership, and identified the exact crossover points where one model becomes cheaper than another. Whether you own a single buy-to-let or manage a growing portfolio, the model you choose today will compound into thousands of pounds saved or wasted over the coming years.
The 4 Property Management Software Pricing Models
Every UK property management software platform uses one of four pricing models: flat monthly fee, per-unit pricing, tiered pricing, or freemium. Each model behaves differently as your portfolio grows, and the best choice depends not on what you pay today but on what you will pay in two or three years when your portfolio has changed. Research from our pricing overview shows that landlords who choose the wrong model overpay by an average of 35% over three years compared to those who match the model to their portfolio trajectory.
Flat Monthly Fee
The flat monthly fee model charges a single fixed price regardless of portfolio size, up to a generous property cap. This is the simplest model to budget for and becomes progressively cheaper per property as your portfolio grows. Latch Pro at £20 per month includes up to 8 properties with full features including MTD compliance, AI assistant, Open Banking, and compliance tracking. Landlord Vision charges approximately £15 per month for its standard plan covering up to 5 properties.
Flat Monthly Fee Model
Pros
- Completely predictable monthly cost that does not change as you add properties within the cap
- Effective per-property cost decreases with every property added — £20/month across 8 properties is just £2.50 each
- No surprise bills when portfolio grows, making annual budgeting straightforward
- Typically includes all features at one price with no add-on charges for core functionality
- Best long-term value for landlords who plan to grow beyond 3-4 properties
Cons
- Higher starting cost for a single property compared to per-unit or freemium models
- Property cap means very large portfolios may need to upgrade to a higher tier
- Less flexibility if you only need software for a short period or seasonal use
Per-Unit Pricing
Per-unit pricing charges a fee for each property or unit managed on the platform. This model is common among agency-focused and enterprise platforms. Arthur Online, one of the most established UK platforms using this model, charges between £5 and £8 per unit per month depending on contract terms and volume. The appeal is a low entry cost for small portfolios, but costs scale linearly and can become the most expensive model once a portfolio exceeds approximately 5-8 properties.
Per-Unit Pricing Model
Pros
- Low entry cost for landlords with just 1-2 properties
- You only pay for what you use — if you sell a property, your bill drops immediately
- Transparent scaling: easy to calculate the exact cost at any portfolio size
- Often includes enterprise-grade features even at small scale
Cons
- Costs increase linearly with every property added, making growth expensive
- A 10-property portfolio at £6/unit costs £60/month — triple the price of flat-fee alternatives
- Budget becomes unpredictable for landlords actively acquiring properties
- The cheapest model at 1 property becomes the most expensive at 10+
Tiered Pricing
Tiered pricing offers multiple plan levels, each with different feature sets and property limits. Landlord Studio exemplifies this model with a free GO plan (1 property), a Pro plan at approximately £12 per month (unlimited properties), and additional premium features at higher tiers. Xero uses a similar structure with Starter (£15/month), Standard (£27/month), and Premium (£36/month) plans, though these are not property-specific.
Tiered Pricing Model
Pros
- Multiple entry points allow landlords to start small and upgrade as needs grow
- Lower tiers are genuinely affordable for small portfolios
- Feature differentiation means you can avoid paying for capabilities you do not need
- Upgrade path is clear and predictable
Cons
- You may be forced to upgrade an entire tier for a single feature
- Feature restrictions on lower tiers can be frustrating — bank feeds, MTD, and reporting are often locked behind mid or top tiers
- Price jumps between tiers can be significant (e.g., £12 to £27 per month)
- Comparing value across platforms is difficult when each defines tiers differently
Freemium
Freemium platforms offer a permanently free tier with limited functionality, generating revenue when users upgrade to paid plans. Latch Free covers up to 3 properties with compliance tracking and tenant management. Hammock offers a free tier with basic income and expense tracking. As our best landlord software guide notes, free tiers are excellent for testing a platform and managing a small portfolio, but they consistently lack the features that save landlords the most time and money: bank feed automation, MTD compliance, and advanced reporting.
Freemium Model
Pros
- Zero cost to get started — genuinely useful for landlords with 1-3 properties
- No commitment or contract required; try the platform with real data before paying
- Sufficient for very basic portfolio tracking and record-keeping
- Good way to evaluate multiple platforms before committing to a paid plan
Cons
- Critical features like bank feeds, MTD filing, and compliance tracking are almost always paywalled
- Property caps (typically 1-3) mean you will outgrow the free tier quickly
- No MTD compliance on any free tier we tested, which is a dealbreaker from April 2026
- Support is typically slower or community-only on free plans
How Each Model Scales: Cost at 1, 5, 10, and 25 Properties
The table below shows the monthly cost of each pricing model at four common portfolio sizes, using real UK platform pricing verified in February 2026. The differences are striking: per-unit pricing is the cheapest option for a single property but becomes the most expensive at 10 properties. For a detailed breakdown of every platform's pricing, see our 2026 pricing report.
| Model | Example Platform | 1 Property/mo | 5 Properties/mo | 10 Properties/mo | 25 Properties/mo |
|---|---|---|---|---|---|
| Flat Fee | Latch Pro (£20/mo) | £20.00 | £20.00 | £20.00 | £20.00 + £2/extra prop |
| Flat Fee | Landlord Vision (£15/mo) | £15.00 | £15.00 | £30.00 (upgrade) | £30.00 (upgrade) |
| Per-Unit | Arthur Online (~£6/unit) | £6.00 | £30.00 | £60.00 | £150.00 |
| Tiered | Landlord Studio (£12/mo Pro) | £12.00 | £12.00 | £12.00 | £12.00 |
| Tiered | Xero Standard (£27/mo) | £27.00 | £27.00 | £27.00 | £27.00 |
| Freemium | Latch Free (£0) | £0 | Upgrade required | Upgrade required | Upgrade required |
| Freemium | Rentila Free (£0) | £0 | Upgrade required | Upgrade required | Upgrade required |
Latch Pro covers up to 8 properties at £20/month. Above 8 properties, Latch Enterprise at £40/month includes unlimited properties, or landlords can remain on Pro at £20/month plus £1 per additional property beyond the included 8.
3-Year Total Cost of Ownership by Pricing Model
Monthly cost comparisons only tell part of the story. The three-year total cost of ownership (TCO) reveals the true financial impact of each pricing model. As our ROI analysis demonstrates, the cheapest platform over three years is not always the one with the lowest monthly price — it is the one whose pricing model best matches your portfolio size.
| Model | Example Platform | 3yr at 5 Properties | 3yr at 10 Properties | 3yr at 25 Properties |
|---|---|---|---|---|
| Flat Fee | Latch Pro (£20/mo) | £720 | £720 | £1,332 |
| Flat Fee | Landlord Vision (£15/mo) | £540 | £1,080 | £1,080 |
| Per-Unit | Arthur Online (~£6/unit) | £1,080 | £2,160 | £5,400 |
| Tiered | Landlord Studio Pro (£12/mo) | £432 | £432 | £432 |
| Tiered | Xero Standard (£27/mo) | £972 | £972 | £972 |
| Freemium | Latch Free then Pro | £720 | £720 | £1,332 |
These figures reflect subscription costs only. They do not include hidden fees such as payment processing charges, data export fees, per-user charges, or add-on costs for features like bank feeds or MTD filing. For some platforms, hidden fees add 30-60% to the headline subscription cost.
The Crossover Points: When Flat Fee Beats Per-Unit
The crossover point is the portfolio size at which a flat-fee model becomes cheaper than a per-unit model. For most UK platforms, this occurs between 3 and 4 properties. Beyond this point, every additional property on a per-unit plan increases the cost gap.
Understanding crossover points is essential for landlords who plan to grow their portfolios. At 1-2 properties, per-unit pricing at £5-8 per unit is cheaper than most flat-fee plans. But the moment you add a third or fourth property, the economics shift decisively. A landlord paying £6 per unit crosses the £20 flat-fee threshold at just 4 properties (£24/month vs £20/month). By 10 properties, the per-unit landlord pays £60 per month — three times the flat-fee cost.
| Flat-Fee Platform | Per-Unit Cost | Crossover Point | Per-Unit Cost at Crossover | Saving at 10 Properties |
|---|---|---|---|---|
| Latch Pro (£20/mo) | £5/unit | 4 properties | £20 vs £20 | £30/mo (£360/yr) |
| Latch Pro (£20/mo) | £6/unit | 4 properties | £24 vs £20 | £40/mo (£480/yr) |
| Latch Pro (£20/mo) | £8/unit | 3 properties | £24 vs £20 | £60/mo (£720/yr) |
| Landlord Vision (£15/mo) | £5/unit | 3 properties | £15 vs £15 | £35/mo (£420/yr) |
| Landlord Vision (£15/mo) | £6/unit | 3 properties | £18 vs £15 | £45/mo (£540/yr) |
| Landlord Vision (£15/mo) | £8/unit | 2 properties | £16 vs £15 | £65/mo (£780/yr) |
Which Model Is Best for Your Portfolio Size?
1-3 Properties
Start with a freemium platform like Latch Free (up to 3 properties) to test the platform and manage costs. If MTD applies to you from April 2026, upgrade to a paid plan with HMRC-recognised compliance. Per-unit pricing is also viable at this size but creates a migration hassle if you grow.
Recommended: Freemium or Low-Cost Tiered
4-9 Properties
Flat-fee pricing delivers the best value at this portfolio size. Latch Pro at £20/month covers up to 8 properties with full features — an effective cost of £2.50 to £5 per property. Tiered platforms like Landlord Studio Pro at £12/month offer a lower price point but with fewer features.
Recommended: Flat Fee
10-24 Properties
Flat-fee pricing is the clear winner. Latch Pro at £20/month plus £1 per additional property beyond 8, or Latch Enterprise at £40/month for unlimited properties, both significantly undercut per-unit alternatives which would cost £50-192/month at this scale.
Recommended: Flat Fee or Enterprise Tier
25+ Properties
Enterprise flat-fee pricing is essential. Latch Enterprise at £40/month covers unlimited properties with priority support and advanced reporting. Per-unit pricing at 25 properties would cost £125-200/month — up to five times more.
Recommended: Enterprise Flat Fee
Watch Out: How Pricing Models Hide True Costs
The subscription price you see on a platform's pricing page is rarely the full cost. Our hidden fees investigation identified 12 costs that UK landlords routinely miss when comparing software prices. Here are the six most common ways pricing models obscure the true cost of ownership.
- Bank feed charges: Some platforms advertise low subscription prices but charge £3-5/month extra for bank feed integration. Latch includes Open Banking integration on all paid plans at no extra cost.
- MTD filing fees: Several platforms charge a separate fee for Making Tax Digital submissions, typically £5-10 per quarterly filing or £20-40 per year.
- Per-user charges: If you manage properties with a partner, spouse, or accountant, some platforms charge £5-15/month per additional user.
- Data export fees: When you need to switch platforms or provide records to HMRC, some providers charge for data exports, creating vendor lock-in.
- Annual price increases: Per-unit platforms can raise the per-unit rate annually, compounding costs for growing portfolios. A £5/unit rate that increases 10% per year becomes £6.66/unit within three years.
- Feature unbundling: Some tiered platforms advertise a low starting price but unbundle features that most landlords need. Compliance tracking, receipt scanning, and advanced reporting may each carry separate charges.
The Verdict
Which Pricing Model Saves UK Landlords the Most?
Flat-fee pricing delivers the best value for the majority of UK landlords. For portfolios of 4 or more properties, the maths is unambiguous: flat-fee platforms like Latch Pro at £20/month cost a fraction of per-unit alternatives and include more features than most tiered plans. Freemium is the right starting point for landlords with 1-3 properties, but the upgrade to a flat-fee paid plan should happen as soon as MTD compliance or portfolio growth demands it. Per-unit pricing is only cost-effective for landlords who are certain they will never exceed 2-3 properties.
Best for: Flat-fee pricing is best for UK landlords with 4+ properties. Freemium for 1-3 properties. Per-unit only for landlords certain they will not grow.
What are the main pricing models for property management software?
The four main pricing models are flat monthly fee (one fixed price regardless of portfolio size), per-unit pricing (a charge per property or unit managed), tiered pricing (multiple plan levels with different features and limits), and freemium (a free tier with limited features and paid upgrades). Each model scales differently as your portfolio grows.
Is per-unit or flat-fee pricing cheaper for landlords?
It depends on portfolio size. Per-unit pricing is cheaper for landlords with 1-2 properties (typically £5-8/month per unit). Flat-fee pricing becomes cheaper at 3-4 properties and the gap widens with every additional property. At 10 properties, a per-unit plan at £6/unit costs £60/month compared to £20/month for Latch Pro.
At what portfolio size does per-unit pricing become more expensive?
The crossover point is typically 3-4 properties. At a per-unit rate of £6, the cost matches a £20/month flat-fee plan at approximately 3.3 properties. At £8/unit, the crossover occurs at just 2.5 properties.
What does freemium property management software actually include?
Freemium tiers typically include basic property and tenant management, manual income and expense recording, and limited reporting. They almost always exclude bank feed integration, MTD compliance, AI automation, and advanced reporting.
How much does per-unit property management software cost in the UK?
Per-unit pricing in the UK typically ranges from £5 to £8 per property per month. Arthur Online charges approximately £5-8 per unit. At 10 properties, this means a monthly cost of £50-80.
What is the cheapest pricing model for landlords with 10 properties?
Flat-fee pricing is the cheapest model at 10 properties. Latch Pro at £20/month covers up to 8 properties, with additional properties at £1 each, totalling £22/month for 10 properties. This compares to approximately £60-80/month on a per-unit plan.
Do property management software prices increase annually?
Most platforms reserve the right to increase prices annually, typically by 5-15%. Per-unit pricing is particularly vulnerable to compounding increases because the rise applies to every unit. Always check terms of service for price increase policies.
What is the 3-year total cost of landlord software?
The 3-year total cost varies dramatically by pricing model and portfolio size. For a 10-property portfolio: a flat-fee plan like Latch Pro costs approximately £720 over three years, a per-unit plan costs approximately £2,160, and a tiered plan like Landlord Studio Pro costs approximately £432.
