Fixed interest rate financing without equity?

What some here have too much of in enthusiasm, you have too little.
It seems that this spontaneous decision about your own house does not please you.
Let it be for now, inform yourself, calculate what financial possibilities you have. I think you have more potential for financing than you think, even with a decent standard of living.
Interest rates have been at their lowest for years, at least that is how the banks argue. Not much will happen in half a year, but you will be more informed and can make better decisions.
During this time you can also put aside some equity.

Quick response on the go :)

Hello Andreas,

The semi-detached house is being built in Middle Franconia. It is not a KfW-70, but a standard-85 house without electric shutters and any other gimmicks. The house will be equipped with a gas boiler, no solar system. Standard doors, cheap fixtures in the bathroom, tiles costing up to 20 euros per sqm included. It is indeed a semi-detached house for the fixed price, which will only be equipped to standard.

The things you describe concern the fittings and therefore have only marginal significance regarding the built-in standard! What is regularly of interest:

[*]is the soil report included in the price?
[*]do you have reserves for possible additional foundation costs?

[*]how is the thickness of the base plate designed?
[*]what does the area under the base plate look like concerning owed earthworks?
[*]with which stone in what thickness or insulation is being built?
[*]how strong is the insulation in the attic?
[*]which windows with what Ug-value are installed?
[*]is there a fixed price?
[*]are there securities?
[*]reserves for extras?
[*]what does the construction contract look like, what is the payment plan?
[*]to name only a few important points ;)

A house built according to the Energy Saving Ordinance does not necessarily have to be a bad investment; however, other things are important than, for example, a material price of €20.00/tiles/sqm.

It is true, notary, property transfer tax and court are not included. The advisor estimated around €2000 for this matter in total, and I said that at least we can manage that from our own resources, i.e. pay ourselves. Is this amount even enough?

Plot & house come from one source, which means that property transfer tax of 3.5% applies to both (if what is stated on the Munich tax office’s website is correct). In your case, €5,617.50; additionally, 2% of the amount for notary and court costs. Honestly: I would send the advisor into the desert because he seems to primarily have his own account in mind, not a satisfied customer!

It was never really a dream for us, only with this offer I thought rather than paying higher rent, I prefer to pay for my own. But now, in terms of costs, it somehow turns out quite differently.

As I already wrote once, there are "bait offers" and serious offers. The way you describe it here, it is quite possible for you to build/buy a property. However, you should then also start from realistic values and not dream that the house building project can be mastered in Bavaria with €190,000. From my experience, that simply cannot be right; positive feedback from acquaintances notwithstanding (you should also not underestimate that builders who have been treated badly rarely — at least face-to-face — are honest).

Find an independent financing broker you trust and discuss the possibilities of financing with him. Only when this has happened will you reliably know how much money you can put in under which conditions without subordinating your life to the house building!

Rhenish regards

Please please inform yourself with other consultants and construction companies before signing. That can never work.
