Land purchase: Questions about the notary

Hello everyone,
we want to buy a plot of land in Thuringia, but the current owner lives in Saxony-Anhalt and also wants to appoint a notary there for the official purchase completion.
Are there possibly any disadvantages here: property transfer tax is the same in both federal states..., other fees, special features, independence (actually regulated by law)???
Do my wife and I actually have to sign together? (She is currently immobile and therefore cannot come to the notary)

Thanks and regards

No, no disadvantages (except travel costs). If in doubt, the seller can also make a sales offer that you accept at your [Notar].

You can even represent your wife without power of attorney when signing the contract. She then has to approve the contract retrospectively. As far as I know, this can also be done at your [Notar] (and not the seller’s).

As a buyer, however, you have the right to choose the notary yourself!

If that were the case, it wouldn't help anyway. The seller could then also sell to someone who notarizes there. ;)

You are probably right there ;)
What a dilemma

Is that really stated anywhere?
