Home financing with another property

Hello dear home builders and experts,
for the construction of our house, we plan to partially finance it through loans on two [ETW]. The remaining amount will then be covered by KfW and bank loans for the house to be built.
The underlying idea behind this financing model is that if income decreases, the [ETW] can be sold, thus allowing the house itself to remain.
The servicing of the loans for the [ETW] is done through rental income.
I am very interested in your opinions on this.

Thank you and best regards for the weekend

A home loan is tied to the house, after all the bank is listed in the land register.

Do I understand correctly that you want to build and at the same time buy 2 condominiums? You must be doing really well :)
What if the rent for the condominium doesn't come in?

Not necessarily. Sometimes the bank even prefers if an existing property is used as collateral for a newly developing property. This was the case with my parents, it is less risk for the bank (after all, the construction is already completed). The exact arrangement must be discussed with the bank.

No, I read: the condominiums are free of encumbrances there. They get a mortgage imposed on them. They pay the rents. The money from the mortgage flows into the new building. The rest through a mortgage on the new building. Uncertainty: Good tenants? Do they pay? Are the condominiums in good condition? What if something comes up? Otherwise: Do it. Smart model. Also saves taxes on the rents, since the interest on the mortgage is part of the costs. Karsten

No, the condos are owned and are to be encumbered with loans. Both condos are rented and, given the location and amenities, will likely remain so. The loans taken out for the condos appear as equity in the house construction.

Hey, it's great for the bank and you. More security, better interest rate. You will probably have to split the loans too; otherwise, I see problems with early repayment in the foreclosure process. Just ask the bank.
