On the one hand, we only gave notice today and thus still have three months - the handover of the house will be in about three to four weeks. Then comes laying the floors and assembling the furniture. We will only take the couch and dining room from the current apartment. The rest will be newly purchased, as the other things are all quite old.
Therefore, we have at least 6-7 weeks of leeway for everything - and since our current landlords will not relet the apartment, we could, if necessary, also store some things there temporarily. We live in the same house as our landlords and have a good relationship.
Nevertheless, it will be exciting - my brother-in-law actually wanted to help us lay the floors. We'll see if that will be possible then.
