Well, the traffic values of the banks are NOT market prices!!! The banks themselves say that their tables used for valuation are usually already very outdated and then they also have super strong safety deductions, etc. So you can't rely on those values at all. We bought our apartment at price X and completely renovated it. Afterwards, it was equivalent to a new-build apartment, although it was only 5 years old at the time of purchase. We lived in it for three years and the market drove the prices in the area up tremendously. So afterwards, we listed the apartment ourselves on ImmoScout for price X plus our renovation costs and an additional market premium from our side. The buyers of our apartment financed through the same bank as we had done three years earlier... And what did the bank do at the beginning??? They simply valued the apartment at the price we had bought it three years earlier... "A revaluation is not planned even three years later!" was their statement... So much for banks and their valuations. In the end, we sold the apartment at our desired price as well. Today, 1.5 years later, the apartment would be even a decent bit more expensive! Markets are just extremely intense at the moment when it comes to price increases... But what else are people supposed to invest their money in if they are rather risk-averse.
