Mietmakler: Complete Guide 2025 & Tips

Looking for an apartment in Berlin, Munich or anywhere in Germany? This 2025 guide explains everything about rental agents “Mietmakler”: costs, rules, advantages, and smart ways to save time and money in today’s tight market. Imagine scrolling through hundreds of listings, sending messages that never get answered, and racing to viewings that are already booked. That’s everyday life for most people hunting for a rental in Germany right now. With more than half the country renting and only a limited number of flats available, the market is still tough in 2025 – even if rent increases have slowed down a little (around 3.5 % year-on-year).

This is exactly where a rental agent “Mietmakler” can help. Think of them as your local friend who knows every landlord and every hidden gem. In this guide I’ll walk you through everything you need to know in plain English.

Key Takeaways

• Rental agents like Mietmakler cut your search time by about 30 % in a market where good flats disappear in an average of 23 days.
• Thanks to the “Bestellerprinzip” rule (since 2015), the person who hires the agent pays – almost always the landlord.
• Maximum commission: 2 months’ cold rent + 19 % VAT (often €1,200–€2,000 in big cities).
• 2025 trends: more digital tools, AI matching, and a growing focus on energy-efficient homes.
• Choose certified agents (IHK-registered) to avoid scams and get the best service.

What Exactly Is a Rental Agent?

A Mietmakler is a professional middleman who connects tenants with landlords. There are roughly 70,000 licensed real-estate agents in Germany, and they handle about 75 % of all private rentals. Their job is to save you time, stress, and sometimes money.

What They Actually Do

• Search for flats that match your wishes
• Arrange and accompany viewings
• Check your documents and credit score (Schufa)
• Negotiate conditions and rent price
• Prepare the tenancy agreement and hand over the keys

For tenants, it feels like having a personal assistant. For landlords, it’s a safe way to find reliable tenants quickly.

Tenant vs Landlord Perspective

Tenants get speed and insider knowledge. Landlords get professional marketing, proper tenant screening, and almost no vacant months. Many expats, for example, happily pay an agent (or have the landlord pay) because the Mietmakler explains German contracts in English and handles all the bureaucracy.

The Legal Rules in 2025

Germany loves clear rules, and renting is no exception.

The “Bestellerprinzip” – Who Pays the Agent?

Since June 2015, the person who orders the agent must pay the bill. In 95 % of cases that’s the landlord, because they instruct the agent to find a tenant. Maximum legal commission for the ordering party: 2 × cold rent + 19 % VAT Example: €900 cold rent → max. €2,136 (including VAT)

If you as a tenant hire an agent yourself (rare), you would pay, but only with a written contract.

Common Traps and How to Avoid Them

• Viewing fees or “reservation fees” are illegal.
• Any extra charges beyond the legal maximum can be reclaimed for up to three years.
• Always ask to see the agent’s official permit and double-check who really ordered the service.

Costs and Benefits

How Much Does It Really Cost?

In practice, tenants rarely pay anything because of the Bestellerprinzip. When landlords pay, the typical commission in big cities looks like this:

• Berlin: €1,200–€1,800 on average
• Munich: €1,800–€2,500
• Smaller cities / rural areas: often below €1,000

Pros and Cons at a Glance

Advantages

• Much faster search (often 1–3 weeks instead of months)
• Access to “off-market” flats that never appear online
• Professional negotiation and contract checking

Disadvantages

• High cost (for the landlord, which can make them picky)
• Some agents are pushy or hide information

For most people in competitive cities, the time and stress saved outweigh the (landlord-paid) cost.

2025 Market Trends

Rents are still rising, but slower than in 2021–2023. Energy efficiency and digital tools are the big new topics.

Digital & AI Tools

Platforms like Immowelt and Immobilienscout24 now use AI to suggest perfect matches. Many traditional agents like Mietmakler offer virtual tours and digital signing. Result: deals close 20 % faster than five years ago.

Energy-Efficient Flats Are Hot

Homes with good energy ratings (A or B) get 25 % more applications and can often command slightly higher rents – but tenants save on utilities. Smart agents highlight these properties first.

Regional Differences

• Berlin & Munich: still very competitive, agents almost essential
• Eastern Germany & rural areas: easier to find flats without an agent
• University cities (Freiburg, Heidelberg, Tübingen): extreme pressure every semester start

Practical Tips & Alternatives

How to Pick a Good Agent

Real-Life Examples

Success Story – Landlord in Hamburg

A three-bedroom flat in Winterhude stood empty for weeks. After hiring an agent like Mietmakler: professional photos, energy-certificate highlighted, rented in 15 days at €1,350 instead of the planned €1,250. The commission was easily covered by avoiding two months of lost rent.

Saved from a Mistake – Tenant in Cologne

A young professional almost paid an illegal €400 “contract fee”. One quick call to the local tenant association “Mieterverein” and the money was refunded the same week.

FAQs

Who pays the rental agent in Germany?

The person who hires the agent pays (“Bestellerprinzip”). In almost all normal cases that’s the landlord. Tenants only pay if they personally instruct the agent in writing – which is very rare. This rule has been in force since 2015 and is still unchanged in 2025.

Are rental agents free for tenants?

Yes, in the vast majority of cases. Landlords pay the commission (up to 2 months’ cold rent + VAT). You only pay if you specifically hire an agent yourself to search exclusively for you.

What are the advantages of using a rental agent?

Faster search (often 1–3 weeks), access to flats that never go online, professional contract checking, and less stress – especially useful in competitive cities like Berlin, Munich, Hamburg or Frankfurt.

How is the commission calculated?

Maximum legal fee = 2 × cold rent + 19 % VAT. Example: €900 cold rent → €1,800 + €342 VAT = €2,142 total, paid by whoever ordered the agent (usually the landlord).

How do I find a good rental agent in Berlin / Munich / etc.?

Look for IHK-registered agents with strong recent reviews on Immobilienscout24 or Google. Many larger agencies offer English service for expats. Always have an initial meeting before signing anything.

Are rental agents useful for expats?

Absolutely. Many agents specialise in English-speaking clients, explain German tenancy law in plain English, prepare bilingual contracts, and help gather all required documents (Schufa, salary statements, residence permit, etc.). Well worth it when you’re new to the country.
