The Mid-Term Rental PMS Gap Is Global: Software Gaps Across Spain, Germany, the UK, Japan and Brazil

In the United States, the case that no property management system was built for monthly rentals is by now well made. Furnished Finder's growth figures, a joint report with AirDNA and a 136 percent surge in stays of 28 days or more all point the same way, and the evidence has held up.

Less attention has gone to the rest of the world, where the problem looks much the same. In eight major markets outside the United States, there is no purpose-built, commercially available property management system for mid-term rentals. In most of them, operators rely on the same workaround American operators used around 2022: a channel manager attached to a spreadsheet, a local lawyer drafting each lease by hand and a bank transfer for the deposit.

Taken market by market, the gaps follow a pattern, and the pattern is not a coincidence.

Spain, the one exception

Spain has the only purpose-built mid-term rental platform native to the European Union. Lodgerin turned its operator tools into a product called Arrento in April 2025 and describes it as "the only all-in-one solution that allows property owners to market and manage mid-term rentals." The company defines mid-term as one to 11 months, the legal threshold under Spain's Urban Leasing Law, the Ley de Arrendamientos Urbanos, beyond which a stay becomes a long-term contract.

Arrento covers the essentials: listings with photos, an availability calendar, digital contracts, booking coordination, integrated payments and a tenant app, Arribo, for check-in and messaging. By the end of 2024, Lodgerin reported 92,000 rentable units in 32 cities, more than 9,000 users and positive EBITDA of 15 percent.

What it lacks is just as telling. It has no native connection to Airbnb or Booking.com, little presence outside Spain and Portugal, and a business model that sells first to universities and corporate mobility departments rather than to individual owners. It is a real, working product, and it shows that European operators will adopt mid-term software when it exists. But it is small, and it is confined to one corner of the continent.

Germany's short-term incumbent

Germany's leading channel manager is Smoobu, a Berlin company that serves more than 30,000 properties (some sources put the figure above 60,000) across more than 50 booking sites, including Airbnb, Booking.com, Vrbo and German platforms. It scores 4.4 out of five on Trustpilot and 4.5 on G2, and pricing starts at €15 a month per property. It has no native mid-term module.

Operators who run furnished stays of 30 days or more on Smoobu do it by raising minimum-stay rules and switching off automated messages that assume a new guest every week. Leases, deposits, recurring billing and owner statements do not exist in the platform. Operators in Germany, Austria and Switzerland either attach a local residential system (Inmovilla, Hektor or tools in the orbit of HAUSGOLD, none of which connect to booking sites) or cover the gap by hand.

The broader point applies across the European Union. There is no combined stack of channel manager, lease, payment and corporate mobility invoicing. American operators approximate one by combining Hostaway, Baselane and DocEndorse. Europe has no equivalent.

Britain's build-to-rent surge

Britain's build-to-rent sector reached 45,000 operational units in 2025, up 15 percent from a year earlier, according to Lambert Smith Hampton's 2026 BTR Report. The pipeline is substantial, and single-family rental and co-living operators in the middle of the market, with five to 50 units, are expanding quickly.

The Renters' Rights Act 2025 adds pressure, with new deposit protections, tenant screening obligations and notice requirements that bear specifically on furnished monthly operators. The companies that have to absorb those rules, including mid-market single-family, co-living and corporate furnished operators, have no dedicated system. Large institutional landlords use custom enterprise software. The middle of the market uses QuickBooks and spreadsheets.

Portugal's forced migration

In Portugal, policy on short-term rentals in designated "contention zones" has effectively ended new renewals of local accommodation licenses, known as AL, in Lisbon, Porto and other areas. Owners who cannot renew are moving to furnished lets of four to 12 months, which are classified differently under the law, taxed differently and require different paperwork and a different lease.

The shift is abrupt, forced by policy and happening across 2025 and 2026. At a minimum, owners making the move need a lease that complies with Portuguese law, documentation to reclassify their registration with RNAL, the national registry for local accommodation, and DAC 7 reporting under the European Union's tax transparency rules. No available system handles that workflow.

Japan's rulebook

Japan's short-term rental market is governed by the Private Lodging Business Act, the 住宅宿泊事業法, which caps minpaku, or private lodging, at 180 nights per property per calendar year. Amendments in April 2026 tightened the rules further. Owners who do not live in Japan must now formally engage a licensed residential lodging management company, a 住宅宿泊管理業者 or kanri-gyosha, and reports to the Japan Tourism Agency, the 観光庁, are required every two months.

Properties in designated wards can apply for Special Zone Minpaku status, which lowers the minimum stay to two nights but requires a separate license. Storing guests' passport scans under a compliant retention policy is required by law.

No commercially available system handles the kanri-gyosha relationship, the agency's bimonthly export format or the identity archive that local law requires. Operators get by with shared spreadsheets, local lawyers and manual submissions to government portals.

Bali and Southeast Asia

In Bali, the market for furnished monthly stays is tied to the visa system. The B211A stay permit and the E33G remote work visa bring in guests who plan to stay longer than tourists do and who come with different compliance requirements. The Pondok Wisata licensing system determines which properties may legally host them.

A local tool, Rental Auto Pilot, serves part of this market with basic features, mostly calendar and messaging. Owner statements across currencies, such as for an owner whose accounts are in dollars or euros but whose Bali property earns Indonesian rupiah, are handled by hand across the market.

Thailand is going through a similar shift. Its DTV visa, valid for five years and allowing continuous stays of 180 days, is expanding long-stay supply faster than the tools to manage it. No channel manager in the Thai market offers a native lease module for stays of 30 to 180 days.

Brazil's tax overhaul

Brazil's 2026 tax reform, the move to the new IBS and CBS taxes, is the largest restructuring of the country's indirect tax system in decades. For short- and mid-term rental operators it brings new complexity: apportioning IBS and CBS on rental income, overlap with the municipal ISS tax, electronic tax invoices known as NF-e for operators above certain revenue thresholds, and a 90-day boundary that decides which legal category a stay falls into.

PowerHost, Stays.net and Sua Temporada are the main Brazilian systems for vacation rental operators. As of mid-2026, none has automated the IBS and CBS rules or built logic for the 90-day boundary. The window is narrow. Operators who adopt a platform that automates these obligations in 2026 will avoid a manual compliance burden that will only grow as enforcement tightens.

Portugal and Spanish-speaking Latin America

Portugal's situation creates a geographic cluster. Spain has Lodgerin, Portugal is wide open, and Spanish-speaking Latin America, including Colombia, Mexico, Argentina and Chile, has no purpose-built mid-term platform of any meaningful size.

Operations in these markets look alike. Sales happen directly over WhatsApp because no booking site dominates. Prices are set by hand in local currencies with no benchmark data. Leases come from templates drafted ad hoc by local lawyers, and payment arrives in cash or by wire, which creates reconciliation problems for owners receiving money from abroad.

Four gaps that repeat everywhere

Across the eight markets and several data sources, the same four gaps appear without exception.

The first is leases and channel sync in a single product. American operators approximate it with several tools, and Lodgerin comes closest as a single product, but only in Spain. Everywhere else, the lease and the booking-site connection are managed separately.

The second is detection of regulatory boundaries: Brazil's 90-day threshold, Japan's 180-night minpaku cap, Portugal's contention-zone rules and the deposit requirements of Britain's Renters' Rights Act. No available system watches these limits and warns the operator before a stay creates a compliance problem.

The third is owner statements across currencies. An owner whose accounts are in dollars or euros but whose revenue arrives in rupiah, Thai baht, South African rand or Mexican pesos faces a reconciliation task that no platform currently handles in one workflow. Paying owners is the last manual step in every international mid-term operation surveyed.

The fourth is a local compliance archive. Identity documents (passports in Japan), government filings (RNAL in Portugal), tax records (NF-e in Brazil) and lease templates (everywhere) are not stored anywhere with a proper audit trail and search. The regulatory record lives in email threads and shared drives.

Who feels it most

The operators most exposed are not landlords renting a single apartment in Lisbon. They are portfolio operators managing 20 to 200 units across several cities or countries, for whom the manual work of compliance, currency and owner reporting multiplies with each new market. For them, the missing software sets a ceiling on how large they can grow without hiring in proportion to the portfolio.

The United States recognized the gap first because the demand signals there, from Furnished Finder, AirDNA data and the growth of corporate housing, made it visible. But the gap exists wherever the supply of furnished monthly rentals is growing, which as of 2026 means most cities in the world.

RentOS, the company that publishes this blog, builds software for monthly rental and flex living operators, with leases, recurring payments, security deposits, owner statements and payout tracking built into the platform rather than added through tools designed for nightly rates. Operators running mid-term rentals in any of these markets and handling these tasks by hand can request a demo at rrentos.com.

Frequently asked questions

What is a mid-term rental PMS? A mid-term rental property management system is software built for furnished stays of 30 days or longer. It differs from short-term rental software, which is designed for nightly rates and frequent turnover, and from long-term residential software, which is designed for annual leases and stable tenancies. It handles what monthly rentals require: recurring billing, a lease for each stay, security deposits managed according to local rules, owner reporting and extensions.

Which countries have a purpose-built mid-term rental PMS in 2026? Spain is the only major market with a commercially available, purpose-built platform, Lodgerin's Arrento. Germany, Britain, Japan, Bali, Brazil, Portugal, Colombia, Mexico, Thailand and South Africa had none as of mid-2026. Operators there combine short-term channel managers, local residential systems and spreadsheets.

What is the EU mid-term rental software gap? The European Union has no combined stack of channel manager, lease, SEPA payment and corporate billing to match what American operators assemble from several tools. Smoobu, the leading short-term channel manager in Germany, has no mid-term module, and Beds24 and Hostaway are likewise built for short stays first. Lodgerin's Arrento is the only EU-native mid-term platform, and it is limited to Spain and neighboring markets.

What does Brazil's 2026 tax reform mean for rental operators? The IBS and CBS reform restructures Brazil's indirect taxes and adds new obligations on rental income: apportioning IBS and CBS, overlap with the municipal ISS tax, NF-e invoicing above revenue thresholds and a 90-day boundary that sets a stay's legal category. Operators on existing short-term platforms such as PowerHost and Stays.net will have to manage these obligations by hand until purpose-built automation arrives.

What is Japan's 180-night minpaku cap? Under Japan's Private Lodging Business Act, the 住宅宿泊事業法, homes operated as short-term rentals, or minpaku, may operate for no more than 180 nights per calendar year. Owners who do not live in Japan must engage a licensed management company, or kanri-gyosha, and file reports every two months with the Japan Tourism Agency, the 観光庁. Properties in designated Special Zone wards can qualify for a different regime with a two-night minimum, under a separate license. No commercially available system automates these requirements.

What is RentOS? RentOS is a property management platform built for mid-term rental and flex living operators. It handles lease generation, recurring monthly billing, security deposits, owner statements and payout tracking in one place, for stays of 30 days or more. More at rrentos.com.
