Interest rate development current situation. Build now or wait?

And with 100% "value increase" and a market value of maybe €800,000 for a single-family house, where only €200,000 (out of €400,000) are still outstanding in the financing, quite substantial amounts arise for the partner continuing to use it.

The typical house is definitely not worth €800,000. Maybe more like around €500,000, if at all. And even if there were still €200,000 of credit outstanding, you can finance the sum of €350,000 for a modest thousand. Or less with lower repayment. That is easily manageable. Single parents who are also working are financially well positioned.

The typical house is certainly not worth €800,000. Maybe more like around €500,000, if at all. And even if there were still €200,000 in loans outstanding, you can finance the sum of €350,000 for a slim thousand. Or less with lower repayment. That’s easily manageable. Single parents who also work are financially well positioned.

Where do you still get a 10-year-old single-family house for €500,000 today? Ypg already wrote from a metropolitan REGION, not a metropolis: €600,000 for a leasehold house. And to finance €350,000, the remaining partner must have an income of ~€3,500 net, then it can work out. 25 years until retirement (divorce at 40), repayment €1,000 to €1,100. Feasible. With a normal full-time income or the desire for part-time, it looks different.

We did the landscaping on the slope ourselves in El, that's not for everyone. In the first year nothing, only small things fixed by ourselves and installed a gate in the garage. In the 2nd year the wall about 50 meters with stairs 8000 euros material In the 3rd year the driveway terrace slabs 5000 euros material ...

That means for you every year after moving in there are still 4000€ extra costs that have to be raised. That’s exactly what I mean, for most people that is simply too much. It makes more sense to budget that straight away in the house construction. To my knowledge, landscaping is also added to the mortgage lending value so that the additional costs remain within limits.

I can't imagine that in many cases - only if there's a lot of goodwill involved.

That doesn’t necessarily have to be goodwill, cold calculation works too. No one has the money left over to pay the other out and no bank will give another loan for that. Paying out means selling and selling means moving into a new apartment for both. Finding something nice is not necessarily easy and rarely cheap. Plus possibly an early repayment penalty which makes it even more expensive. In the end, it’s a classic cooperation game. If both parties compromise it’s win-win; if both are confrontational it’s lose-lose. It’s also best for the children if they can continue to live “at home.”

That’s true – but labor costs when having things done even more so. The choice between expensive and extremely expensive.. ;) But it has already been said here, this is a luxury area, whoever wants everything now and immediately without effort just needs money. It also can be stretched over time and reduced in demands.

As mentioned above, it is not necessarily sensible to plan with a financial requirement of 10,000€ or similar from ongoing salaries. Better to budget it right from the start, at least the important things. Something will certainly become more expensive for us too, the planned buffer might not be enough and the emergency buffer will have to be used, and I wouldn't want to live on the construction site for years stretched out until the money for the landscaping is enough. And in the worst case I can still take the landscaping as a buffer. Doing it yourself is clear, operating an excavator is also much more fun than painting ;)

An intermediary once said that you should calculate 100 times your net income and this amount is usually the maximum loan amount or the point at which the bank starts to get uneasy.

However, that calculation is too simplistic. After all, it makes a difference whether I am single earning 4,000 euros net per month and financing/building/buying alone, or whether I am the sole earner with 4,000 euros net per month and still have to support my wife and children with it.

In the first case, I can easily repay 1,500 - 2,000 euros per month, in the second case hardly more than 1,200 euros. And of course, this also determines the maximum possible loan amount.

I haven't read the entire thread, but I can give an example: We looked at a prefab house in 2015 and fell in love immediately. It fit the plot, we really liked the style and layout. The house was including the foundation slab but without painting and flooring. The cost was supposed to be about €225k at the end of 2015. We decided against it to wait and see if having children would work out. At the beginning of 2019 (January) we decided on exactly this house that we had looked at in 2015. That was before a price increase (so the 2018 price). The cost for the same level of completion was already €256k. Today (price for 2021) the house costs €295k at the same level of completion. Now, without comparing the construction service descriptions exactly, that is... ...with 3 price increases from 2015-2018 = €31k or 4.6%/year. ...with 3 price increases from 2019-2021 = €40k or 5.2%/year. To cover these increases, we would have had to save €860 or €1,111 per month (inflation would still have to be deducted). I find that quite "hefty," unfortunately I didn't have that much wage increase during that time :D In hindsight, I shouldn't have waited, but whatever, it is what it is :)

...with 3 price increases from 2015-2018 = 31k€ or 4.6%/year. ...with 3 price increases from 2019-2021 = 40k€ or 5.2%/year.

I can confirm these price jumps, over a similar period and for several prefabricated house manufacturers.
