You have to earn very well to come up with 200,000 to 250,000 euros in such a short time if you only save.
The thought also occurred to me, and I seriously wonder how that is supposed to work under normal circumstances. Not to be misunderstood, I sincerely wish it for everyone, but having saved 250,000 euros at 29??? Let’s assume the saving period was 12 years, so you started at 17. Then I come to 250,000€ / (12 * 12) = 1,736,...€ that you put aside month by month while still partying, financing living expenses, and maintaining a car. Respect! I lack the imagination of how that should work and at the same time I feel really bad because I seem to be the biggest spender [emoji23]
To the actual question: I thought similarly 4 years ago in a similar situation. Already planned two to three houses in detail to have the right house ready for different plot situations and only find the plot. But it turned out differently: one, exactly one plot found after four (!) years of searching with 420 sqm (always looking for 500 sqm to 600 sqm) and it was over with the own house designs. Went to the architect, communicated the ideas and wishes, and got a floor plan for me and my wife for this plot with its peculiarities and restrictions of the development plan. Very satisfied, would never have come up with the floor plan ourselves and would have built way too big (much too large traffic areas e.g.). Meaning, first find a plot with a development plan that allows your architectural style, then reconsider whether wishes have not changed over time, clarify what you need, and off to the architect. It feels like something on your wish list will have changed in 5 years, then you are in your mid-30s and probably also in a different phase of life...
In between: keep saving equity capital, but please don’t forget life. Equity-wise, you already have very solid conditions now; no need to overdo it [emoji6]
