Since I apparently overlooked at first that it is supposed to be a weekend house, I am withdrawing my statement about the equity from the existing property.
since this construction project is anyway only a second house, which is intended to be used as a weekend house.
I also overlooked the underground garage. In this respect, I would reconsider the costs of the project (very neutrally)
Construction or purchase costs (including architect, structural engineer): estimated 1,000,000 - 1,500,000
800 sqm in high-quality and extravagant execution are definitely not 1,000,000 - 1,500,000, that is much more: At a minimum of 3,000€/sqm we are at 2,400,000 for the house, for the 400 sqm cellar for the vehicle fleet we take 1,000€/sqm... with additional construction costs we are at 3 million. Then a plot of land of 500,000, on the outskirts of the province... well then: there are now 150,000€ equity against that. That brings me back to my first note -> there is no financing from the bank, no matter how large and lucrative the practice is. Furthermore, such a project is practically unsellable by the bank in case of disposal, because the market has no buyers.
Cost breakdown: Total costs: 1,500,000 Deductible equity: e.g. 150,000€ Financing amount: 1,350,000€
800 sqm of living space is not that much. For example, a generous guest area, ballroom, and a matching kitchen are sufficient. You can also use up the space very quickly if you "appropriately" display art.... There are no limits to imagination.
In my opinion, the art should hang here in the notary’s office. In terms of costs, a crazy idea. My advice: take the 150,000 equity, lease a big motorhome instead of a 3 million weekend house and present yourself with it - there are always admiring eyes that you can impress. But envy is something else. It is not always envy when down-to-earth fellow humans find something great, but too huge and unnecessary - and therefore doubt the motives, especially in today’s times.
