Hello everyone!

After having been here as a reader for a while, I have now decided to actively participate here (with questions! Unfortunately, my expertise is not enough for answers).

Who we are:
A brief introduction: we are a family of six, facing a move due to my husband’s job. It doesn’t have to happen immediately. Currently, my husband commutes, and the pressure is not too high. In the medium term, however, we would like to relocate our main residence closer to the job.

We are not really set on building, but after longer observation of the market, we notice that we either have to rent a dump or spend a horrendous amount of money—or hope for a lucky hit (the real estate market is unfortunately not designed for large families. Almost all offers are poorly laid out / too small. Sometimes they do exist, but due to distance, we are often simply too slow). The same applies to buying houses. Somehow, the market is pretty much fished out.

So we are now considering building as more or less a Plan B and are slowly feeling our way into it. However, we (still!) are complete beginners and don’t have much of a clue. So I’m hoping for answers to many silly questions here.

What we are looking for:
We don’t need luxury, want to plan ahead (the kids will eventually move out), want to be reasonably energy efficient and (if possible) have a clear, straightforward architecture. Specifically, a house without unnecessary frills. Ideally planned as a house with "two living units." Not only because of the double KFW funding bonus (although as a layperson, I don’t really understand that yet and am not sure if KFW loans are really top of the list—probably a topic to think about separately later)—but also so that later, when the kids have left the house, we won’t be stuck in a house that’s too big for just the two of us.

We want to build cheaply, but not cheaply done. Specifically, well thought out about what is really needed, reduced to the essentials, and (in many, but not all (!) areas) preferably with relatively simple fittings. Currently, we live in a (very well laid out!) house with 140 sqm. In our opinion, with considered architecture, it doesn’t have to be much bigger than that.

How expensive will it be?
I keep coming across prices per square meter when it comes to building. Often it is said that you can build for €1100 per sqm with simple fittings, up to €2000 for a house with more upscale fittings (there is, of course, no upper limit). But I wonder: can you really build a decent house for €1500 per sqm? When looking through various prefab house catalogs, that seems way too low to me. But I am very happy to be proven wrong.

Cost calculation:
We don’t want to build recklessly. Primarily, we are currently trying to figure out whether we can afford to build at all. So here’s an example calculation that keeps going through my head for you to look over. Please: where is the flaw in my thinking? What have I overlooked?

House, 150 sqm – €225,000
Plot, fully developed (just picked one randomly—it can be somewhat cheaper, but also much more expensive) – €35,000
Ancillary building costs (according to the forum here) – €40,000
Garden – €10,000 (probably set too low. But definitely an area where we can do a lot ourselves)
Reserve for: something goes wrong / becomes more expensive / whatever – €10,000
Reserve for extra items (in case of doubt a new kitchen or a carport) – €10,000
That adds up to €320,000

Architect costs are not yet included. No idea what that costs.

If I enter this into a financing calculator, it spits out an offer (loan amount minus our equity) 15 years term, 2% effective annual interest rate for about €900.
But besides the KFW thing, there is also the option to get a loan of €125,000 from the Investment and Structural Bank RLP. Term also 15 years at 2.0% or 10 years at 1.6%. Not really cheaper, but special repayments of 10% per year are possible. Interesting for us because in a few years a second income will come in, which we won’t need fully for living expenses (currently one is enough).

I find that insanely cheap and wonder: what have I overlooked? Where is the mistake? If this calculation is even remotely realistic, building a house would be very pleasant to accomplish.
If you also calculate €400 ancillary costs per month, we would pay the same as currently in rent. But with a new build near the job, the daycare fees would disappear (+ €250 per month) and my husband’s travel costs would roughly halve (+ €250). So we would have a surplus of €500, which we could save.

Currently, we live on one income only. Within five years at the latest a second income will come in. When the loan expires, at least two, probably three children will have left the house, so the "granny flat" could be rented out.

Otherwise, I basically wonder how to approach the whole thing sensibly. How do I find someone who will build for the above price (if that is financially feasible. If we want to build, then solidly financed. Surely three vacations per year won’t be possible anymore. But the kids should still be able to continue riding or music lessons). How can I survey the (completely confusing for me) market? Is there a good book on the subject? Or other tips for our first steps?

Many thanks already at this point,

kauderwelsch (that’s how the building topic feels to me right now)

Hello
The error in your calculation probably lies partly in the incorrectly targeted house price. 1100 is definitely not feasible (even if others base themselves on cheap construction methods) and rather applies to shell houses. Prefabricated houses in catalogs are usually only priced in the standard segment – the house presented is shown with a lot of special equipment. So don’t be fooled.
I’m not very familiar with current regional construction prices, but where in RP is the building supposed to take place? And how realistic is the land price?
For 6 people and their living space consumption compared to a rental apartment, storage rooms and technical rooms are also added.
You probably have to calculate 1800 to 2000 if you can’t do much on the construction yourself.

In short: best treat the topic very pedantically first, how much the entire house construction may cost you in terms of income. Then, based on the real land price, how much house you can afford. You are not far off with the remaining costs, you are just a bit confused now
A cheap plot of land should also be buildable without extra costs, regarding the soil but also the zoning plan, allowing you to put up a simple house

Hello,

a few remarks:

I am not familiar with KFW funding, but is there a bank similar to Bayernlabo in Rhineland-Palatinate? That would definitely be interesting with four children in the household, as there are subsidies for each child. However, then you can no longer receive KFW funding.

You won’t be able to build anything for €1,100. I would consider €1,500 at least here in Bavaria as an absolute minimum. We built for about €1,700, and everything is nice but no luxury included. No dormer, no bay window. No huge glass fronts etc. Flooring and painting also cost extra. Have a look at the big red construction company, they are inexpensive but solid.

For 6 people, I would calculate at least 150 m2 x €1,700, so a house price of €255,000.

As for the financial planning, it’s hard to say, you have to calculate that yourselves. But you state €10,000 for other things (kitchen). Not much will be left if that is even enough for a kitchen.

Just arrange for a meeting with a company of your choice. Then you will see further. There’s not much to do with catalog prices...

I would not calculate under 1800Euro/m2, which makes 270,000€ for 150 m2 as a house with a foundation slab. Very roughly, you can expect 20-30% additional costs, with a lot of personal contribution and a flat plot possibly 20%, otherwise 30%. That puts you at 350,000. Then comes the [Grundstück]. And additional expenses for the kitchen, new furniture, and lamps.

Thank you all!

Just very briefly: I calculated above with €1500 per sqm. So that is unrealistic? What a pity!

That is the investment bank RLP I mentioned above. The loan does not actually become cheaper, only special repayments are possible and they secure it subordinately.
