Limit sounds good, I hope to finally be able to sign a loan by the end of this month (we are waiting for the approval of the property). The essential thing is simply that you can no longer save equity quickly enough (against the rising construction costs). Accordingly, if you want to build, you are almost forced to take out a large loan. About 1.5 years ago, we were still expecting a total investment of 300k, now we're looking at a total investment of 560k. If you are still relatively young, then there is simply no equity and you have to take out a large loan (in our case 490k) (or have the building done). I hope that the interest rates will remain the same until the end of the month, even though a historic low is reached every week nowadays...
