The renovation decides your yield
long before the first tenant moves in.
Between an apartment that is hard to let and one tenants apply for, the difference is rarely just location or layout, it is the condition in between. This page covers what a real renovation involves and what to keep in mind when buying a renovated apartment in Germany. It is also, quite openly, a description of how I prepare the apartments I sell.
First, the boundary: what do you actually own?
A German condominium is two purchases in one: your unit (Sondereigentum), which you control alone, and a share of the common property (Gemeinschaftseigentum), which the owners’ assembly controls together. This boundary is the first thing any renovation plan has to respect, it decides what you may touch and who pays.
| Building part | Belongs to | What that means |
|---|---|---|
| Flooring, interior doors, bathroom fittings | Your unit | You decide and pay alone |
| Non-load-bearing walls, wall surfaces | Your unit | Changes possible; mind impact sound |
| Windows, entrance door, balcony | Common property | Owners’ assembly must resolve |
| Load-bearing walls, facade, roof | Common property | Resolution plus structural sign-off |
| Risers, drains, heating system | Common property | Renovated via the association |
Renovation is more than new surfaces
New surfaces are quick; the real substance of a renovation sits in the technology: wiring, pipes, bathroom, windows, heating. That part is never visible later, and it is exactly what decides how an apartment performs over the years. A good investment is therefore more than a pretty apartment: what matters is the interplay of condition, building, owners’ association, location, lettability and numbers.
With my own properties I know the work that was carried out first-hand, because I coordinated the renovation myself. In the buying process we go through the condition, the relevant records and the owners’-association minutes together, calmly and before the notary appointment.
Why I renovate before I sell
This is exactly where my business model sits: I buy apartments with substance, renovate them consistently for lettability and sell them as finished investments. The renovation risk, trade coordination, cost overruns, is carried before you ever see the property. And because I coordinated the renovation myself, I know the work that was carried out. The results are on the track record page.
For German-reading visitors, the full deep dive, including the tax side of renovation costs and the rules for passing modernisation on to the rent, lives on the German renovation page.
What really matters before you buy
Before buying a renovated apartment, it is not the single line item that counts but the overall picture: the condition of the unit, the situation of the building and the owners’ association, the location, the lettability and the numbers behind it all. With my own properties we go through these points together during the buying process, with the documents on the table and without time pressure. If a property doesn’t fit your strategy, I tell you so honestly.
Frequently asked questions
What is the difference between renovation and refurbishment in Germany?
German usage distinguishes three things. Renovierung is cosmetic: paint, floors, small repairs. Sanierung fixes damage and brings the building services up to standard, wiring, pipes, bathroom, windows, heating. Modernisierung is the legally distinct case: it durably raises the standard or saves energy, and it is the only category whose costs can partly be passed on to the rent.
What can I renovate in a German condominium without asking anyone?
Everything inside your unit (Sondereigentum): flooring, interior doors, non-load-bearing walls, bathroom fittings, wall surfaces. Anything belonging to the common property (Gemeinschaftseigentum), windows, facade, risers, the heating system, load-bearing walls, is not yours alone: structural changes need a resolution of the owners’ assembly, and whoever demands the measure generally pays for it.
How do I know what was done in a renovated apartment?
With my own properties, first-hand: I coordinated the renovation myself and know the work that was carried out. In the buying process we go through the condition, the relevant records and the owners’-association minutes together, so you make your decision on a complete picture.
Is a fixer-upper a good first investment in Germany?
Rarely. A renovation project carries its own risks: trade availability, cost increases, months without rent, and the unforeseen during construction. If it is your first purchase and you work full time, a finished, ideally already let apartment is almost always the calmer decision.
