Is house planning realistic at all?

Dieses Jahr haben wir eine Eigentumswohnung zur Vermietung gekauft

Hello first of all, yes, I too am surprised by the statement, Did all the money come from equity, or did you finance it alone? The bank will probably not grant you a loan at the moment. A trainee salary is not recognized, and looking into the crystal ball regarding a permanent position is not feasible. Equity is too low, just enough for the incidental purchase costs. How come you expect to have this job? Even large German companies have to calculate and do not offer all trainees a permanent position after their apprenticeship... I am somewhat stunned! Yes, and then the age of 20+ is certainly not necessarily the age when you want to invest all your money in concrete – where is the carefree life supposed to be if not at this age? Happy holidays

We financed the condominium. The tenant is currently even paying off the apartment to us with a bit of profit. Of course, when the tenant moves out, a new tenant has to be found. We then have 3 months (notice period) for that. According to the contract, my girlfriend will be taken on permanently after her training.

In my opinion, buying an apartment is not worth it if you do not want to live there permanently.

You currently will not be able to afford the planned €250,000 for a house. Equity is basically zero (I assume it is €10,000 equity), unless there is an "emergency fund" available. You cannot even pay the additional purchase costs. Then there is the question of whether something still needs to be renovated.

In addition, you, or at least your girlfriend, are quite young. Why would you want to commit to a house at 20?

Wait until your girlfriend has completed her training, found a permanent job, and the probation period is over. Until then, you can still save "properly."
