I see this as a transitional property also (unfortunately) very skeptically. Because as mentioned above, the probability is not exactly small that poorly insulated houses with oil heating, which also don't have the right target group (families go for houses over 120m2 and retirees look for apartments around 80m2 on one level), are hard to sell. Who is supposed to buy such a house in a few years? Let's be honest, if the OP renovates it extensively (100k?), they could just buy a nearly new condo with 80m2 and 3 rooms (which are increasingly coming onto the market here, sometimes even with financing takeover at 2%, but the question to you experts is, is that even possible?). So don't panic right before the end and buy a house that might only be worth 180k in 5 years! Better to wait until a suitable property comes along for you, where you don’t end up with a guaranteed loss in value upon purchase but can at least be sure that the value of the house will remain stable over the years (i.e. younger construction <20 years and better insulated).
