Well, even with 25 years, very few people build. You really have to save for several years.
That is basically correct – but as hampshire already said – construction and land costs have risen significantly faster than incomes in recent years. A "typical" €350,000 house from the general contractor could next year be offered again at 5% more according to the price list. €17,500 additional costs, meaning the "savings rate" alone has to be almost €1,500 per month just to keep up with inflation. Let’s assume the prospective builder already owns a plot of land. To build up equity, which is needed to get construction financing at reasonable interest rates in the first place, at least €2,000/month would have to be saved. "Net," that results in a ridiculous €6,000 equity advantage per year. This must then reach an appropriate loan-to-value ratio. From this you can see quite well in my opinion that we really are talking about a bubble here. The pool of potential players is decreasing year by year.
At the same time, the municipality will not let the great market situation (of which it is, of course, completely innocent) pass by, meaning land prices will also be pushed up vigorously.
Since this pattern appears everywhere, the locksmiths’ arguments about €6,000/month salaries don't help. Such incomes are rare and also not evenly distributed regionally. The end will come when the pool of potential buyers is exhausted and the real enablers of the game pull the plug – the banks.
Because the "price increases" in construction are not "real," i.e. not the result of broad inflation across society, but special effects – they are milking the cream. A house from 2015 from a standard general contractor is pretty much the same as in 2020 – so why should it be 25% more expensive? And from the bank’s point of view – will they realize such a large delta again for an identical building at a forced auction? Or is there just too much room, such that those are just enthusiast prices?
The current tightening in loan approvals regarding collateral speaks volumes. Banks see the risk too, and only as long as the borrower pays for the hot air with their own money are they still in. A good income alone excludes you – only those who can also blow grandma’s inheritance up the chimney are still in the race.. ;)
The problem with that – grandma’s inheritance first has to be able to be sold at the desired price – the same applies there..
