Indeed, the property is reserved until 30.06 and would be a dream because of the described advantages regarding location/infrastructure/proximity to the grandparents. KfW 55 would be easily achievable with these 700,000€ according to the architect. For the time being, we have to trust the man and wait for the design and advice from the energy consultant.
Initially, we have 1100€ available just for the children (and food and drink are already covered) and the financing of two cars (which, by the way, would be paid off after about 5 years). With the 1100€ buffer, we still believe we are living large for a 700,000€ project. If necessary, we could well increase this amount to 1500€, of course combined with corresponding renunciation of pocket money, expensive brand products, etc.
Our repayment plan foresees repaying the KfW loan first, which would free up an additional 350€ after a little more than 10 years... plus salary increases of the next two performance levels (+ approx. 450€ + approximately 1.5% per year).
When leaving kindergarten, another 700€ will be added, as the childcare costs will then disappear.
So a few years after starting elementary school, we would have 2600€ - 3000€ available just for the children. Even if we then set aside 500€ monthly for special repayments + the 4000€ tax refund, 2000€ - 2500€ remain. Each year the financial burden decreases, the second of three loans will be paid off and again about 250€ more will be available.
Shouldn't such an amount be sufficient? I really don't want to make myself feel better at all costs, but shouldn't this be feasible? Am I making a serious mistake here?
