We have been managing apartment buildings and buy-to-let properties in Frankfurt and the Rhine-Main area for over 20 years. Our team truly knows the city and its mix of nineteenth-century buildings, post-war housing and modern quarters. Frankfurt is dynamic and demanding, from dense inner-city locations to mixed-use developments and established residential areas in the surrounding region. We are fully prepared for this.

Your house
in safe hands
Managing a property in Frankfurt requires market knowledge, diligence and a high level of reliability. That is exactly what you can expect from us. We look after properties in the Rhine-Main area with a clear structure, personal accessibility and a commitment to long-term quality.
With more than 10 colleagues, we manage over 2,000 units in Frankfurt and the Rhine-Main area. By merging FAJA Immobilienverwaltung with Theo, we combine established local experience with a strong national network of experts and a management system that consistently takes the next step towards digitalisation. This creates a service philosophy that combines tried-and-tested methods with contemporary structures.
Our long-standing work as district managers for the main section of the Zeil has shaped us in a special way. Working with the city, residents and service providers requires a broad perspective, tact and clear coordination, qualities that now benefit every property we look after.
All managers in our team are certified in accordance with Section 26a of the German Condominium Act and are available as your dedicated contacts. We also support you during sales and lettings with sound market knowledge and the right contacts. This way, you can be sure your property is in safe hands at every stage.

Switch to Theo:
Simpler than you think
Get in touch with us to explain your situation. We will give you an honest assessment of how and when you can make the switch, even if you have an active management contract.
We will prepare a transparent quote and present ourselves to your advisory board or the homeowners' association. This helps the homeowners' association get a clear picture.
For the switch to take place, you only need the resolution from the owners. By the way, under section 26 paragraph 3 of the German Condominium Act, you can dismiss a property management company at any time. In this case, the existing contract will end six months later at the latest.
We guide you through the handover process step by step. We coordinate agreements, request the necessary documents, liaise with service providers and banks, and set everything up so that your business continues without interruption. This involves very little effort for you.

Frequently asked questions
We are happy to help
Why should I let Theo manage my property in Frankfurt?
Because you have a team by your side that knows the Frankfurt market and works in a structured way. With the experience gained from the former FAJA Immobilienverwaltung, we manage over 2,000 units and combine regional expertise with clear processes and personal support.
Which properties do you manage in the Rhine-Main area?
We manage homeowners' associations, apartment blocks and mixed-use buildings in Frankfurt and the surrounding areas. We look at each property individually, designing processes to suit the structure of the building and its owners.
Do you also manage properties outside Frankfurt?
Yes. We work across the entire Rhine-Main region, looking after properties in cities such as Offenbach, Bad Homburg and Darmstadt. It is important to us that we can reach your property easily and be reliably on site.
How do you switch to Theo?
Changing your property manager is easier than you think. We handle all communication with your previous manager, sort out notice periods, review files, and ensure nothing is lost. This requires barely any effort on your part, as we guide you through the process step by step.
Will I have a dedicated contact?
Yes. You will have dedicated contacts from our Frankfurt team. They will know your property, be directly reachable and guide you through all important matters, from the annual owners' meeting to maintenance planning.
How do you ensure transparency in your administration?
With clear processes, straightforward billing and open communication. Property owners always know which measures are planned, why they are necessary and what the costs will be. Decisions are documented transparently so there are no surprises.
How quickly do you respond to technical or organisational problems?
We work with local tradespeople and service providers in and around Frankfurt am Main, which means we can react quickly. Damage, technical faults or urgent matters are logged promptly and supported through every step of the process.
Do you also help with renovations and modernisations?
Yes. We support maintenance, modernisation and energy efficiency measures, from preparation and obtaining quotes to implementation. Throughout the process, we keep a close eye on costs, schedules and the owners' requirements.
How do you ensure your property maintains its value over the long term?
Through forward-looking planning, regular property inspections, structured maintenance schedules and solid reserve management. We make sure that measures are taken in good time so that the property remains technically and financially stable.
How much does a good property management service cost?
The costs depend on the type, size and requirements of your property. We prepare a tailored quote for each property. This is of course non-binding, transparent and with no hidden costs. It is important to us that you know exactly what you are paying for and the added value you receive.
