Is the overall cost estimation realistic?

50% of the property value + sum of the RLV + other. You can quickly gather the 500k

Yes, I was mostly referring to the RLV alone and wanted to make clear that 20,000 EUR is obviously laughable in comparison
But enough about tax law – any general tips? I am especially uncertain about the amount... does the entire loan amount really have to be covered or can the RLV simply be considered as "starting capital" for the partner in the worst case?
I will have to declare a chronic illness in the health questions. It's not bad enough to lead to rejection, but it will probably show in the premium. It is all the more important for me to go through all the options.

I would not make the topic of RLV dependent solely on the house or the underlying loan. Consider what it would mean for you if the other person were no longer there, especially if children were involved later on. Single parenthood is an enormous risk of poverty.

We have decided that only my husband will take out a RLV. He earns enough to be able to cover the installments + living expenses for our daughter on his own if necessary (at the moment he is also the sole earner and his salary will soon make a significant jump upwards and continue to increase afterwards). I would be totally overwhelmed with my (soon to be) salary. As an amount, we took (roughly) the loan sum. I have a good feeling about it this way and apparently he does too.

Okay, thanks! Our salary distribution is not comparable to yours (currently 60% / 40%), I think we will both take out one or take a joint one. But good to know that you have based it on the loan amount. Our loan will start at around 350,000 EUR. I would already find that quite a lot as an insurance sum. After 6-7 years we would still have an outstanding debt of 300,000 EUR. Maybe take something in between as the insurance sum, or even a linear decreasing amount. Difficult...

I am already in the process of comparing a few insurances, but would also like to read your opinions / approaches on it.

I will have to indicate a chronic illness in the health questions. It’s not so bad that it will lead to rejection, but it will probably have an effect on the premium. All the more important for me to go through all the options.

Go to a broker. There are many RLV policies that don’t really present their conditions on the internet. We were also a bit worried about the health questions, but at least the broker was able to present 2 that had a significantly shortened health questionnaire if the contract was signed within 6 months after concluding a mortgage financing.

A falling premium was also not really worth it (the usual suspects on online portals were all a bit expensive despite falling premiums). That’s why we only took 275K fixed instead of with the initial value of the 325K loan.

We decided that only my husband will take out an RLV. He earns enough to be able to cover the installments + living expenses with our daughter alone if necessary (he is currently the sole earner and his salary will soon have a significant jump upwards and will continue to rise afterwards).

One should not forget that differences in income are only one aspect. A single parent usually has other disadvantages (childcare, working hours, etc). Insuring only one of them ignores these aspects.

In addition, we took out 2 single policies mutually.

That means not only the 1st death triggers the payout, but also the 2nd; or if both simultaneously.

In that case, our son is the beneficiary (and receives accordingly much).

We currently have the same issue, the loan is even higher than yours. We will probably choose around 80-85% with RLV and insure each other. We will keep the RLV running consistently for 25 years. If, for example, we both die in an accident, the money goes to the children or the guardian we have designated.

, could your husband still work full-time if he had the children alone? Usually the answer here is no, it would also be impossible for us. And then the question is whether you can still keep the house if you can only work, for example, 75%.
