New construction with KFN 297, building savings and interim financing

1. With a net income of €2,900 and no proper rental of the second residential unit, you will fail with a €1,600 installment at most banks (since we work with several hundred banks ourselves, I can say that this would be the case - it misses the mark by exactly €100). 2. Proven regular income from securities is recognized as income (usually a flat-rate taxation after utilization of allowances is assumed). 3. The salary from your own company must be earned sustainably. Banks are generally not interested in more than that. 4. ETFs can be used as additional collateral. However, from a regulatory perspective, they must be valued with significant discounts. In your constellation, I would go through my house bank, even if it may be somewhat more expensive. This bank knows you as a private customer and, ideally, also as a business customer. Financing should not be a big problem there, even with the mentioned ratios and additional collateral.

Regarding 1. If €1,500 would be suitable, at least I have a number I can work with.
Regarding 2. That sounds logical.
Regarding 3. Perfect, the salary is fixed, permanent, regular (for years), and contractually guaranteed.
Regarding 4. Ok.

Although I no longer have a checking account with the regional house banks (only shares with one), privately I am with ING (and part of the ETF shares with another). ING should know my financial regularity (salary deposits).
And professionally I am with Ethikbank, which to my knowledge also offers home construction loans, so I will inquire about that.

Many thanks for the tip & the assessment!

The building savings contracts are quite complicated to integrate, if I read Finanztip about it. Maybe I'm out without even further checking, too speculative. I only had it in mind because in the family a generation above me always had these contracts. But that is probably more for conventional savers who don’t trust ETFs.

Due to the agreed 3% wage increase, I will have at least from 2024, when the money is needed, instead of 2915 then 3002€ net. So presumably 1600 credit installment should be okay.

I am also still waiting for feedback on whether QNG can be achieved – the certification would be included in the price since it’s modular construction. In that case, a 300K promotional loan over 25 years would mean my monthly rate is 1155€. Or with a 20-year term, 1577€ monthly.

That would of course be a dream, as it is very simple and flexible, but now I have to wait for feedback from the provider.

Otherwise, with 25 years, 200K at 1% and 100K at 4.3%, I currently end up at 1360€ monthly, can that be right? That would also be totally fine, and what will happen in 10 years (until then the 150K ETF with reinvestment is running)
