Thank you for your answers.
So, we already understand that painting ourselves would basically be the cheapest option :) Our concern is to save time. The move to our new house will be tightly scheduled at the end of a month, but we want to be out by then so we don’t have to pay rent for another month.
We are both working and have two small children and no grandparents nearby. Something like "painting and renovating the apartment" is a not to be underestimated time factor, especially since we still have quite a bit of renovation to do in the new house together in a short amount of time.
And yes, we will have to paint and renovate. We have lived here for over 5 years, we painted the apartment ourselves and otherwise took it as the first tenant, there are no strict deadlines and we have always had a good relationship with the landlord. Accordingly, we will not try to find any reason to avoid doing anything here, that’s not our style.
We thought that if we buy materials in the mid-range segment ourselves and then find two students to do the work, it would be financially manageable...
That we might agree with the next tenant that they do some painting and we give them money or materials is also an option. But then again the question arises: What do we give them?
