If you go to the bank today with the data, in my opinion it won’t work.
Sustainable income is 3150 + child benefits, from that little rent after taxes, reserves, and non-allocable costs hardly anything will remain. Most banks are not interested in parental allowance.
You won’t get half a million credit with that.
Equity is of course top, but the income is too low for these amounts.
I think you will have to wait until both are working again.
But I see that completely differently. Why shouldn’t parental allowance be considered income? The €1,800 maximum rate is based on a corresponding income before this period. Furthermore, parental leave is very short in relation to the loan term. There are suitable models for that.
500k credit with about €5,000 (3,150€ + 1,800€ + rental income) and the high equity ratio should be easy to get.
Our banker said at the time that customers with such equity are readily accepted. (The good customers meanwhile are equipped with suitable loans and almost only 100% financings remain)
From a financial perspective, it is feasible... So why not?
