Purchase opportunity single-family house from the 80s - risk?!

Side question: we still have a building savings contract funded with 30k, we could take another 30k as a loan (without entry in the land register) at 2 percent (interest and repayment). So 60k equity, so to speak. Or better to keep saving?

Interest on deposits close to zero?
I would definitely use that, realistically you would otherwise finance the money at at least 4%.

We had the same situation, but even before the big interest rate hammer was swung. The location, the neighbors, the layout of the house (built in 1978) fit perfectly. Renovation start on April 2nd, when the electrician unloaded his materials. Planned were attic insulation, a new guest WC, a new main bathroom, partially new radiators, partly new doors, refinishing the parquet floor. Estimated costs: 50,000€. What it turned into: the planned work, completely new window installations, rebuilt and properly insulated roller shutter boxes, a pretty smart home (we didn't want that, but it's great), new electrical system with network and photovoltaic preparation, covered terrace. Now, after a good half year, we are living in a solid old building that is energetically sound and we feel great. It turned out to be significantly more expensive than planned, but what you don't do in an unoccupied state you definitely won't do afterward. 20-25% of the purchase price fits as a rough rule. Important in my opinion: good neighbors, good location, good foundation for renovation. Ultimately, I calculate financing a bit differently. I take into account that later I don't have to fear rent increases, but only have to pay my fixed rate plus a certain maintenance reserve. Until retirement, then the place is paid off. If the monthly burden fits and life isn't restricted…why not?

Great closing speech
That's exactly how it is

The location, the neighbors, the layout of the house (built in 1978) fit perfectly. Renovation started on April 2nd, when the electrician unloaded his material. Planned were roof insulation in the attic, a new guest WC, a new main bathroom, partly new radiators, partly new doors, refinishing the parquet floor. Estimated costs: €50,000.

Well, I would have calculated that higher too ;) But what I somewhat want: I ask you why and whether the planned modernizations were really necessary? I also bought a detached house from 1978 – okay, in 1999 – but (I am just realizing for myself that the house was only 21 years old back then)… I often simply doubt the necessary modernization costs: painting walls and mostly floors, yes. But does there have to be an immediate exchange of doors and sanitary fittings? The charm of the used goes away, but even worse are the costs.

Electrical system almost 50 years old, no RCD, 1st and 2nd floors including attic on a single (!) fuse. If you expand the system, the grandfathering protection is lost. If you’re going to do it properly, then also network, plenty of sockets and photovoltaic preparation (cost approx. €16K). Windows were from the house's construction year and did not exactly contribute to comfort. You notice it extremely after replacement, especially since it also made sense energetically (according to energy consultant). Costs for this approx. €10K, depends on the area. Plus properly insulated roller shutter boxes (was a major weak point). Doors were for the look, bathrooms were 70s orange, turquoise, brown. Don’t get me wrong, everything was well maintained, but just very old. And before I tackle the electrical system and bathrooms in an occupied state… now the gable wall insulation is still missing, but that’s next year. If someone asks me what it cost, I say: 8-10 kilograms and nerves, but it was worth it :p

yeah… you’re right…!

But… I hope I’m not confusing this thread with other parallel threads, you can also spruce up doors and tiles with colors and visually renew them, at least for the first few years, so that you could save about €50,000 in total.
