House construction costs

Question about the house construction costs. We are planning our house and do not exactly know how we need to finance what?! How do you proceed when you want to think of everything - keyword taxes, mortgage, repayment, and so on and so forth?

First, one should first compile their own resources, equity, own contributions, building savings contracts, etc., then check how high the monthly burden can be so that one can still live and possibly bridge losses at least temporarily. From this, possible loans and the affordable building sum result. Now one must consider whether the money is sufficient for the intended house.
