This "smaller" increase from about 5,600 gross to 7,100 gross per month is actually a bit unusual in such a short time, but congratulations. You usually only achieve such an increase by changing jobs? 3,800 is actually more like 2,300 than 2,100 according to my calculation, but never mind.
My opinion hasn’t changed. Do it. It is now, of course, significantly more comfortable.
In the meantime, something has changed on our income side, I was able to achieve a "smaller" increase.
Our situation now looks like this:
Me: €7,100 gross = €3,800 net per month, bonus annually additionally €10,000 gross = €5,000 net
Her: €3,800 gross = €2,100 net per month, bonus annually additionally €8,000 gross = €4,000 net (unchanged for now).
Our annual tax refund will, according to my first forecast, be around €3,500.
That means we now have €5,900 net per month and about €12,500 net annually available, so the annual net salary is €83,300.
How do you see the project under these new conditions?
Otherwise, the framework conditions are relatively unchanged, we are currently tending more towards KFW55 in solid construction, but we would rather invest the "savings" compared to KFW40/KFW40+ in larger "buffers" in order to definitely be able to realize the building project within the budget.
Thank you very much for your feedback.
