Build a home? Land in prospect

Hello house building forum,
I have been reading the various posts here in the forum for some time now and thought I should finally register.
I am currently in the rough planning/idea-finding phase, considering the sense and nonsense of creating our own home. Until recently, I did not want to build, but the idea keeps growing and growing.
Before I throw myself into this adventure, I would like to gather various opinions (friends, acquaintances,... [Hausbau-Forum]) about my plan.

About my situation:
I have a plot of land in prospect. Cost: €60,000 incl. all additional costs. Regarding the house, I imagine a small single-family house with 115-120 m² + basement. After extensive research and meetings with construction companies (no concrete offer yet, only rough calculations) a turnkey price would be about €170,000 - 180,000.
Thus, I assume total costs of €270,000. (€60k land, €180k house, €30k additional costs). However, this is calculated completely without own contribution. So there is still a buffer, as we will do some things ourselves.
The outdoor facilities,... will then be created later by ourselves. So I will leave that aside for now.

Now to the actual thing, the financing:
Currently, we have about €80,000 in equity. (scattered everywhere: building society savings contracts, regular account, real estate funds, stocks, savings plans,...)

Including a safety buffer, €200,000 would have to be financed.

After deducting ALL daily living expenses I can pay off AT LEAST €1,000 per month. As I said, at least. Normally it is more, but you should always assume the worst case. Until today I have not been to a bank to ask whether this is possible.

First, I wanted to hear a neutral opinion from you.

Thanks for your help.

Regards
Kwa

Maybe important: I have actually planned everything into the monthly installment payment. (Living expenses, insurance, additional house costs, water,..... buffer for a broken car, buffer for house repairs,....)<-- and even €50 monthly for vacation ;), which I can of course also do without.

Hello Koala,

sounds pretty okay. For me, the numbers are almost exact. If more is possible, keep it at €1000 so you have room to build reserves and then use the special repayment option when convenient. €1000 is also an amount that you basically pay for a 4-room apartment.

Just from experience, you always find things you want (for example, for me: I had electric shutters, but the timer control is extra or underfloor heating includes a surface-mounted thermostat, surcharge for flush-mounted). That costs a lot more money and doing the garden yourself still costs materials!

ok thanks, I have an appointment with an independent financial guy over the weekend. Let's see what he offers me. I will definitely get your opinion before I sign anything.

If this post is in the wrong forum, please move it.

Now I have a plot of land in sight. The following situation: The plot is 667 m² in size. The location is first-class. For me, it is very, very good because it is directly on the highway and I can be very mobile and flexible. The costs amount to €49,000 (fully developed) + additional costs. So the price is also great. The problem is the building ground. No soil survey has been carried out yet. According to the seller's information, the building ground is mostly sand. The neighbor said it is the best building soil. A bit of both. The municipality also said that it is mostly sandy soil. In addition, the plot has a SLIGHT slope. Now I am considering whether I should accept the offer. I think, since the building ground is not the best, increased costs will definitely come up. But even if an extra €10,000-15,000 were added, the plot would still be cheap. Of course, it is best to have a soil survey carried out and to have a construction company estimate the costs. But if I have a soil survey done, then the location of the house must be precisely determined, right? All these things would take quite a lot of time and I am afraid that the plot will be gone then... Can you give me tips?

Edit: Now I think I was wrong. Sand is actually a good building ground, isn’t it?
