Is additional financing possible or necessary?

Ok, thanks

But from your perspective and with my, albeit rather sparse, information, a top-up loan should be possible without any problems, right? Or do you think the bank will simply not pay the last invoice and probably won't give me a top-up loan for the amount? As I said, I have no other loans and always pay on time. There are also no entries in the credit bureau etc.

Forget about the top-up loan, of course the bank advisor said you would get 5k, but not on your building loan terms.

Thank you! The question was first of all whether I will even receive the amount in the first place.

So I have to expect around 5-6% interest for the "Nachfinanzierung" and not around 2-3%, right?

You have to ask your bank.

definitely YES!

Apply for a small loan. You can also do that online with other banks. It will then cost you 3.5%

Or first ask the financing bank specifically. You can always get a small loan elsewhere if they do not make a reasonable offer.

The bank would probably settle this invoice initially anyway

No. If you have taken out a classic mortgage loan or something similar, the bank will automatically not give you any more EUR.

So if you know that you need more, it helps to sit down with the bank early to explore the various options.

Because almost always, when the time comes, there is time pressure. And the advisor always has the offer for the small loan ready.

After receiving the last invoice for the planned modernization work, I now realize that the budget has been exceeded by about 4,500 euros.

How do the two things fit together???

3.) Should one refinance early if one notices that the budget is tight, even if it is not yet clear how much the refinancing will exactly be?
