Financing for used property okay?

Building savings contract approx. €11000

Savings balance or building savings amount? If savings balance: What is the building savings amount, when was the contract taken out, what is the loan interest rate, when is it ready for allocation, etc....

possible installment €1000 monthly feasible

I consider that too much given the income. Additional costs must also be paid and reserves must be created.

expenses approx. €600-750

I don't believe that. For 4 people - food, clothing, mobile phone, insurance, building savings, costs for school/hobbies, hygiene articles, vacation, car, other special expenses - Never!

Rent is currently 690 € ([Mietnebenkosten] included) + 100 € electricity. Our expenses are really that low, whether you believe it or not. Okay, vacation is not included but we haven’t had one in the last 3-4 years anyway. So never say never;) Building savings credit is around 11,000 € and the building savings contract sum is 40,000 €, concluded in Nov. 2011.

Sorry, I still don't believe it. Or rather, I think you're just trying to make the numbers look better. Have you really calculated all expenses (including those that occur only once a year) down to a monthly amount? In that case, it would actually be interesting to see a breakdown of your expenses (even if it's not really related to the topic ;)). In terms of food, you can basically count as four "big eaters" given the age of the children, and the building savings plan also needs to be paid. That means even if you had no insurances (which I consider absolutely reckless and not feasible with a house) and no car, it still wouldn't be doable.

Will report after the financing meeting whether it is possible

Hello

due to the income, I am also pessimistic. Even though you have saved a lot with your possibilities! (my greatest respect)

Good luck!

From November/11 until today is roughly 36 months, which means you have been depositing about 300 euros monthly. That’s not too bad. Moreover, I wonder where the remaining 60TEUR come from? Were these "external" influences, meaning one-time donations, e.g., from family, or pure savings from income? If I assume you had 30 years for the equity capital, that would be an additional savings rate of 150 euros. In total, with cold rent + savings rate, you would already be where you want to be.

I think that although it is tight, your savings performance shows that it would indeed be possible for you. I don’t see it as hopeless but rather medium to dark gray at most. There are worse starting points that are financed without batting an eye. Overall, you should be clear about the total costs and unforeseen surprises; that’s where I see the greatest risk.
