House purchase with construction loan repayment rate

3,300 € income (including child and parental benefits) and a loan of 340,000 €. There is also a second child. I find that a bit tight.

Are the 500,000 € for the house all inclusive? So property transfer tax, remodeling/renovation/refurbishment, new furniture, moving, other additional costs?

I also find it tight, especially since rent always carries risk. Equity earned yourself or donation/inheritance? What is currently being saved aside

No, the mentioned costs will be added, whereby only the renovation costs would have to be crossed out once again. Otherwise, everything is great. Equity is an inheritance, whereby a cushion of 50k remains in reserve. Currently, 600€ are saved monthly.

No, the mentioned costs are additional, whereby only repainting would still be due as renovation costs. Otherwise, everything is great.

Equity is inheritance, with a cushion of 50k still kept on the side.

Currently, 600€ are saved monthly.

So we are rather at 600,000 €. From my point of view, that is way too much in terms of income.

Currently, 600€ are saved monthly.

Name the current cold and warm rent. These amounts plus the 600€ savings performance are available for the house plus additional living costs (around 400€ or so). I would initially leave rental income out of consideration for the reasons mentioned. If you still rely on it to avoid making a loss every month, I would stay away from the property.

I would also exclude [Elterngeld], that is temporary. That means you have "only" €3,000 income. But you want to pay:
- €1,100 installment (will be too little)
- €400 additional costs
- €200 reserves
Then €1,300 remain for:
- food
- clothing
- internet, Netflix, mobile phone
- insurance
- excursions
- car (tax, insurance, repairs, fuel)
- etc.
for 3 people. No chance.
