I would probably do without a basement and garage if possible. That will surely save you 50-70k. Then it also looks good if you are unemployed for a few months.
Hi, if the OP actually leaves out both, a saving of >> 100k is possible in the region. Demand is still high there and the supply currently quite limited. But what you mentioned can be had for 250k + notary + trade tax......in view of the existing equity, the amounts are brutally/significantly relativized and would come to a range that would actually be good (= comparatively very manageable).
We also live without a basement: before the move (from 150sqm living space to 110), we did a thorough decluttering, now there is endless space. And we no longer keep anything with the motto "we might need this again". Usually you don’t......A friend of mine recently found jam from 1974 in his parents' basement......I just had to laugh.
Garages: we don’t have those either.......it’s a luxury, personally I don’t need it (nor does my wife) for living.
