We are thinking of a possibility to gift our children an apartment in future, so we would like to know what could be future implications. Taxation for us and a child when she and she would get it.
Here is our idea.
1. Two of us (German residents) buying an apartment in Munich. For example 25/50/100K down payment, 250K mortgage. We pay all related expenses (Tax, notar, makler, etc...). We are paying the mortgage, renting it out for a time before we give it to our daughter. We would use the paid mortgage interest to offset our income, act with like it is ours, since it would be

2. In 5/10/whenever years (she is now 18), once she starts working and becomes capable of paying a mortgage by herself we would gift it to her. She would have to take over the mortgage, if she would not have enough cash to pay it out.
Our question is:
- How that ownership transfer would occur? What would be the expenses? Grundwerbsteuer, Notar, Grundbucheintrag, how the mortgage would be transferred from us to her? Since we have two daughters, we believe that we would be doing the same for the second one too.
- How is the value of the gift seen at that moment? If we decide to gift it to her after 5 years, and home equity goes from 50K (down payment at the time of purchase) to 75K during that period, and the home market value goes from 300k to 350K, is the gift's value 75K or 350K, or something else?
- I know there is a 400K/10 years inheritance limit exclusion in Germany, so I am assuming that this would not be reached, especially since my wife and I would be doing it jointly (800k limit in this case, if I am not wrong).
- Is there any other cost that we are not aware of, or any better idea how to make this work better?
And to add to the equation, all 4 of us are US citizens too. There is a $38K limit per year gift exclusion, but if the gift would be larger than that there is a lifetime inheritance exclusion currently of $13.99M which I am assuming would not be reached: https://blog.taxact.com/gift-tax-calcul ... -tax-free/
