Financial plan for new construction - equity available. Loan of 100K

Hello people,
I'll introduce myself briefly... this is my first post here.
I am 24 years young and am currently considering buying a house with my girlfriend.

New builds are unaffordable and unrealistic for me. I see it like buying a car. I would never buy a new car from a dealer because the depreciation is very high immediately after you have driven off the dealer’s lot. Unfortunately, it’s the same with new build houses.

Long story short. In 2 years we want to buy one. Reason: I will have finished my studies by then.
Equity will amount to 50,000 Euros from me and 10,000 Euros from my girlfriend. Parents contribute 10,000 Euros.
So we would have about 70,000 Euros available.

The house should be a foreclosure property. Because there are not only old houses to buy there but also very nice and relatively new houses.

The loan amount would probably be between 80-100K Euros.

Has anyone already done something like this and can give me tips?

The equity ratio is around 40% based on the planned total costs. That is decent. If the ongoing income also fits the loan rate considering the family situation, nothing stands in the way of the project.

Acquiring a property from [ZV] is usually not that easy. You first have to find the right property (location, size, floor plan, ...). And then you want to win the bid at a good price. Others want that too, of course. Additionally, many properties are already taken before the [ZV] date through negotiations with the creditor. The [ZV] appointment is then canceled. So: with a suitable property, don't wait until the [ZV] date, but contact the managing creditor beforehand and try to reach an agreement. Good luck.
