Since returning to Wolfsburg in 2017, we had been searching for a property. Initially, we rented to take our time finding the right house and to test the real estate agents.
Of course, properties meeting these criteria were expensive and scarcely available. The first viewings were disappointing:
Then, at the beginning of 2018, an offer came up that didn’t fully meet our criteria but was in the same neighborhood.



The house was actually larger than we needed, but the structure and architecture were excellent. Renovations were manageable (utility lines easily accessible, partly in shafts), and the leasehold was acceptable because the owners had prepaid their installments (there was a discount), so the annual fee was only 500€ (~$540). The leaseholder is the city of Wolfsburg, which by statute only raises interest rates upon resale (not during the lease term or inheritance). When purchasing the plot, the land value is calculated by the benchmark land value minus the redemption amount and with a 15% discount. In mid-2017, the offer for the land was therefore 118,000€ (~$128,000) (with today’s benchmark land value it would be about 150,000€ (~$162,000)). This was a bargain for the area and was included in the asking price according to the agent.
Still, after a second viewing with experts (not appraisers), we found enough arguments (wall crack, renovation needs) to negotiate the price down to 420,000€. The public offer was then reduced to 435,000€ (~$470,000).
A financing broker secured approval from the local savings bank (Sparkasse) for the mortgage (leasehold is a bit special here, mostly local banks are familiar). It was feasible as a 20-year full repayment loan (leasehold agreement had to be valid for at least another 10 years), with a potential buffer to save up the land price.
But there was one issue: the over-90-year-old occupant. She was looking for an apartment in a senior residence (ground floor, lake view). Every week we heard it was only a matter of days until one would become available. In the end, by mid-April, we had a reservation with ownership transfer no later than December, possibly sooner. So we committed to financing and arranged the notary appointment...
...and then a week later, there was a request for a meeting (bypassing the notary). The niece and sister explained that the reservation was declared invalid. The time pressure was too great. It wasn’t certain the apartment would be available yet. They felt the elderly woman couldn’t be expected to move into a care home. They wanted a purchase contract with more time — about a year (implicitly without a strict limit).
We only had 6 months interest-free financing extension, but could imagine a few more months. However, only with financial compensation (1,500€/month rental cost difference). The counterproposal was to buy as planned but with ownership transfer only after the occupant moves out (essentially the right to live there). This was not acceptable (due to hardship rules; in the end you own the house but cannot evict the old resident). The only outcome was an informal understanding: we remained interested, please inform us when the senior residence is arranged; if we find something else in the meantime we will get back to you. The agent (VR-Bank) was not very pleased since it had been difficult to get the three women to agree before. It wasn’t her fault; the dossier was the best prepared with all necessary documents and missing items obtained promptly.
Two weeks later there was another interested party. Moral of the story: we successfully lowered the price for others but they moved in in October 2017.
Here are some floor plans of the property as inspiration for other house planners:

The agent mentioned that in the residential area, maybe one property sells every 1–2 years. The rest are sold privately. Since we moved in, three houses have been demolished and replaced by new builds twice the size. Another is still a shell and is receiving a huge extension. None of these properties were publicly marketed...
...the search continues in the next post and how we finally found our home.

- detached single-family house (so no semi-detached houses)
- within walking distance to the city centers of Wolfsburg, Fallersleben, or Vorsfelde
- for existing buildings, construction year from 1960 onwards, even if not renovated, as long as the structure justifies investment (otherwise you pay for poor renovations that need to be redone)
- for new builds, located in a residential area with a coherent design concept (many new developments unfortunately look like model home neighborhoods where every option from the catalog has been used, but without creating a harmonious living environment)
- a larger garden with usable space
- no leasehold (common in this area)
Of course, properties meeting these criteria were expensive and scarcely available. The first viewings were disappointing:
- 5-year-old house in a new development: walls with cracks, water stains (from the foundation slab), unoccupied, agent said normal settlement cracks (but wrong direction and too large), suspected upward ground movement due to Posidonia shale underground according to the land use plan and construction errors
- 8-year-old house in the same development: not legally divided plot (3 houses on 2 plots), agent claimed legal division (sent documents with condominium declaration), neighborhood dispute (not ideal in a condominium under self-management)
- 1950s development house: severe moisture problems in the basement including mold, agent already had an offer for exterior waterproofing (franchise concept with suction lance) which was not expensive, basement height under 1.8m (5 feet 11 inches), so not usable
- 1950s development house: sold after only 2 years (hidden defects?), superficial renovation (cosmetic upgrades but original substructure)
- several other houses that left little impression (location, layout, quality, price not suitable)
Then, at the beginning of 2018, an offer came up that didn’t fully meet our criteria but was in the same neighborhood.
- built mid-1958
- very high-quality construction and workmanship for the time
- architect-designed house (engineer) for a medical professional (MD)
- hillside location, split-level, integrated garage
- district heating with concealed convectors
- well maintained, so renovation was minimal (bathroom tiled + ceramics, new roof 2002, new windows 1995)
- well-kept garden, granite paving
- 165m² (1,776 sq ft) living space + 40m² (430 sq ft) utility space
- 905m² (9,740 sq ft) leasehold plot at a dead-end street
- 493,000 €

The window in the laundry room caused more problems. Although we warned the window installer after removing the inner wooden window that the window he offered would not fit as is, he was unwilling to come by before installation to find a joint solution.

After removing the steel window, the problem becomes clear:
(20.05.2020)
The outer window sill extends inward. The window installer wanted to simply place it on top (with minimal overlap and no connection profile) or in front of it (leaving a corresponding gap to the side). Additionally, there was a 5cm (2 inches) frame extension at the top to allow the window to open inward without hitting the heating pipe. However, when measuring, he was instructed to remove this extension and measure the full possible height.
We agreed to remove the upper profile extensions and instead add a lower connection profile. Lead time was 4 weeks, allowing enough time to adapt the opening to the requirements.
Same opening without outer window sill.
(20.05.2020)
Size test with window frame and bricks:
(20.05.2020)
Masonry completed inside and outside, interior sides plastered and secured.
(20.05.2020)
(05.06.2020)
Fully installed window:
(16.06.2020)
The installer sealed the side and top edges with compressible sealing tape against the exterior wall. At the bottom, it rests only on expanding foam, which was also used to insulate the sides and top from the inside. Therefore, I will need to handle ensuring a rainproof connection to the masonry on the exterior that complies with RAL standards.

In the garden, another attempt was made to further reduce the occasional moisture in the basement.
The house is built on a slight slope. Over the years, more and more soil was added and the terrain was somewhat evened out. Unfortunately, it was also piled too high, allowing moisture to penetrate the masonry more easily. As shown in the pictures, the soil was piled well above the bituminous coating:
(April 8, 2020)
(April 16, 2020)
Curbstones installed
(April 23, 2020)
The downspout had once been replaced by the original owner with a copper pipe. However, the roofers left the last few decimeters of the old cast iron standpipe in the ground…
(April 19, 2020)
Then the bituminous coating was partially renewed.
(April 23, 2020)
Finally, 16-32mm (0.6-1.3 inch) gravel was added, the gravel level being about 20cm (8 inches) lower than the lawn.
(May 21, 2020)
The roof of the conservatory drained through a spout directly into the area in front of the large window. The effect is clearly visible on the soil bases of these BEGA outdoor sockets. The left base was installed there, the right one elsewhere in the lawn.

The spout was cut off and a new copper pipe was connected to the existing downspout from the roof:
(May 9, 2020)
Then it was soldered, and the next temporary solution was completed.

However, the heavy rainfall last weekend showed that the drainage urgently needs to be redone. It is better than before, but moisture is still visibly being pressed into the basement.

A tool shed is currently being built to allow the demolition of the patio cover and the shed next to the garage:
(June 15, 2020)What kind of slab is that? Is it the base slab of the garden shed?Definitely a very cool project. And a great example of how much effort goes into a precise renovation.
This is a ground screw foundation with a concrete slab from Biohort. A Highline H3 will be placed on top of it.
I am worried about the carpenter. He was hired on March 31 to build the frame for the kitchen sliding door. He said the wood (white oak) needed to be imported from the USA and, due to COVID-19, he expected a delivery time of 4-6 weeks. After that, he could start, but he would get in touch as soon as the materials arrived. After four weeks (April 29), I asked for an update on the delivery for the first time, and he asked for two more weeks.
So on May 11, I called again: there had been a large fire at the industrial port in Bremen, which affected the import wood warehouse as well. He is waiting for feedback from the supplier, who needs to first sort out the still sellable stock and possibly reorder the wood. He said he would get back to me by Friday with an update. No call came on Friday, and he was also unreachable. So I tried again on Monday: he said he would come to install in five weeks.
Now the five weeks have passed, but no frame has been installed. Yesterday I couldn’t reach him (only voicemail, once an employee answered with “the boss will call back by noon”) and today there was only voicemail again. However, when my wife called from a different number, he answered immediately: he is still waiting for information from the wood supplier. He said he would get back today.
Is it really this difficult to obtain wood for a door frame within 12 weeks? Under what conditions can I cancel the contract and find another carpenter? Might I be obligated to accept the wood if it eventually arrives (advance performance)? The order is worth about €1,800 (material/labor not itemized separately in the offer).
There is a written offer and our acceptance of it. The rest of the communication has been by phone.
