Would you wait with a construction project because of this crazy price spiral, or should that not matter? According to the motto: It won't get any cheaper anyway?
I would probably make it dependent on age and life course. For my husband and me it would make no sense to wait any longer, because then we would be dead beforehand. ;-) I think if money is tight, building now as relatively "simple" as possible (with the option of later expansion, perfection, adjustment, ...) would be my choice. We are now also doing this out of necessity, due to the price increase of our house builder. The amount of rent in the desired residential area as well as the amount of available equity, which is reduced by inflation and penalty interest rates, should in my opinion be taken into account, as well as the number and age of the children. New, more environmentally friendly building regulations, which in the short and medium term may no longer be compensated by subsidies. Perhaps also the reduced designation of building areas.
what signs do you see that interest rates will rise again?
The FED is gradually, albeit gently, raising interest rates.
