Financing Land & Corner Bungalow

I have informed myself about deferred taxation here in the forum :)

Whether the residential Riester is used has not yet been finally decided - I would also make it dependent on the value of the shares. (higher price, or lower)
As of today, there is €12,000 in it, it could also be further funded & included after the end of the term, but as I said, no decision has been made yet.
I would also be very grateful if you could provide some assistance in this regard.
How have other former builders done it?

Your mentioned retirement provision should then be our house.

A 20-year fixed interest rate is only feasible with a significant surcharge - if you make good special repayments in the last 10 years with the 15-year one, you should actually be able to compensate for that & the residual debt is no longer so high.
Provided you discipline yourself :)

I would like to use the special repayment to keep the outstanding debt manageable after the 15-year fixed interest period.

What does the flexible repayment agreement cost in interest premium? Is it only marginal?

Life insurance risk definitely comes into play.

No idea what surcharge is added. It was offered to me directly without asking for it separately ;). We could permanently reduce our rate by a good 20% with it, which gives a good feeling.
I find it - for security reasons - significantly more attractive than a special repayment option that is rarely or never used (because the money usually flows into other directions anyway - be it the garden, vacation, new furniture, vacation, new car, etc.).
Definitely use an intermediary (Interhyp..., Dr. Klei...) as well.

How much does the flexible repayment agreement cost in terms of interest surcharge?

Many banks now offer this as a standard feature.

Previous financing with Sparda, where you can change the repayment rate annually between 1-4% throughout the entire term. I was also able to make special repayments in any "extra installments" over the entire year without any interest surcharge.

Current financing with Sparkasse, repayment change possible 2 times within 15 years.

I would have loved to stay with Sparda, but they did not undercut or match the offer from Sparkasse.

Ps: I also recommend an independent financing broker. The offer from Sparkasse was not even beaten by an insurance company and over 15 years that was a savings of over 14,000 euros in interest compared to Sparda!

I'll ask the house bank if they offer repayment changes within the fixed interest period.

We have also been to 3 other banks & credit brokers, the problem is that the house bank (Sparkasse) made the best offer & the advisor finally said that she still sees some room for maneuver if we receive a better offer - unfortunately, that hasn't worked out so far :(

I have to say that we were about to schedule a notary appointment (developer), but due to atmospheric disturbances, we ultimately decided not to build with the developer.

Now we are looking for a suitable plot of land & still want to get some basic opinions on the financing.
So basically starting from scratch up to the draft (only small changes left).

everything depends on and is tied to our income, if that from the woman disappears (not a civil servant & not in public service), it looks bleak...

The question is, if it then disappears, exactly when it disappears, if it is immediately after the financing, 1-2 years later, it will very likely be more than hairy.....
I'm already envisioning the worst

As a banker, I can tell you that your financing offer is solid and fits your income based on the framework data. Sure, maybe you can get it 0.1-0.2 cheaper somewhere, but it probably won't be much more than that.

We are currently also financing through a financial broker (Hüttig & Rompf) and have gotten 2.42% for a 20-year fixed interest period (that is one of the components, otherwise there is another annuity loan and KfW twice). However, we also have – as already recommended – a repayment rate adjustment right included. We can change the repayment rate every year from 1% up to max. 5% repayment (calculated on the initial loan amount). That makes you quite flexible.

And yes, just as user "Punica" writes: If one partner’s income drops out, things get tough. However: That happens with almost every couple, you can read about it in various discussions here in the forum. Please make sure that both of you are well insured for both death and occupational disability (both!!!! spouses). Then, to be honest, I would have little concern given your framework data (rule of thumb: Don’t spend more than 30% of net income on the mortgage rate).
