Follow-up financing experiences?

If I were you, I'd really be afraid. Without Dad, the lights would go out pretty quickly! But hey, I'm sure you still have enough to get there if it goes wrong :) what are you worried about? Daddy will take care of it, right? Honestly, I don't understand.

What does this have to do with my father now? What is he supposed to regulate? Why should the light be off when he is no longer there? The question is simply how to best design something like this in the future.

Well, I am only a teacher too, so nothing special,

That's why you have to ask here as well (a little joke on the side ;) ) Yes, time and your dad meant well for you :) Write off your own and finance the rental!

The house (approx. 310m2) has 3 rental apartments generating 3300 euros per month. After deducting the bank installment, I am left with 1800 euros. The loan for this house still runs for about 10 years.

How about rent increases? What would be possible over the next 10 years?
Ultimately, if it doesn’t pay off: sell.

For now, I would also make special repayments on the single-family house, but only a little. I would first save money to build liquidity in case something unexpected happens with the multifamily house: repairs, rent defaults, etc. That might help against sleepless nights.

What does that have to do with my father now? What rules is he supposed to make? Why should the light be off when he is no longer there? The question is simply how to best arrange something like this in the future.

The choice of your title "sleepless nights" suggests that you are seriously worried. That means, without daddy you would already be finished anyway.

I would really be scared in your place. Without Dad, the lights would go out very quickly! But hey, you surely still have enough to get there if things go wrong :) what are you worried about? Dad will sort it out, right? Honestly, I don’t understand
