So about 1.5 years ago, we also financed 110%. Both in our late 20s and earning 5,000 net at that time. However, with 2% repayment and 2.4% interest. The Volksbank just agreed to that without much discussion. I don’t know how it looks today, but make appointments and see what the banks say. Our advisor calculated everything back then, including parental leave, unemployment benefits, and so on. We also did it ourselves again and decided that it was feasible for us with a 1970€ rate. But to be honest, it was already tight, but doable. Meanwhile, each of us earns 300€ more net and with that, life is pretty comfortable. Moving in is in two weeks and with interest + rent, we currently pay even a bit more than we will later in the house.
But to be honest, with a rate of more than 2,000€, we would have shelved the dream for the time being. That really was our absolute pain threshold and you have to be honest with yourself. I would recommend you to do a household budget. Make a few Excel sheets and see what is possible for you. Of course, you can live well on a small budget, but I would plan at least 500-600€ pocket money per person for consumption expenses (shopping, eating out, cinema, clothes, activities), besides all other costs. Also don’t underestimate how much money will go to spontaneous purchases, especially in the beginning. Tools, non-financeable fees, mailbox, plant here, piece of furniture there. We solved it so that each of us has 850€ pocket money and can spend that freely. We simply take turns doing the shopping. Everything else goes into the joint account. This way, after fixed costs, we still save around 300-500€ a month.
That brings us to the 40,000€ you have budgeted for renovations. You will never get by with that. Alone for the above-mentioned “small things” we have paid 5,000€ since signing and we are basically building turnkey. The kitchen is also rather around 10k-15k. I would still plan at least 20,000€ as a buffer.
