General questions about house construction / house purchase

We have equity. I just don't know how much. There is a contract that I received for confirmation where I only pay 40€ monthly. Then there are 2 grandparents and 2 parents who each have contracts. Unfortunately, I have no idea how much exactly they include. I would not even remotely consider doing a 110% financing. And as for the area... we quickly said goodbye to Hamburg. It would rather be in the surrounding area... Properties there have not yet reached 500k+. The idea with the land is an interesting one...

You still seem pretty naive and I already know that you absolutely should wait a bit longer.

New construction cheaper than existing properties? How do you come up with that? New construction is ALWAYS! significantly more expensive. Of course, you must not compare existing properties in a good location with new construction in a bad location. If the location is similar, new construction is considerably more expensive! Period.

You have equity but don’t know about it? I have no words... before I come up with the idea to write in a forum, I’d at least think a little myself, right? And that naturally includes the question "how much money do I even have". At least it’s positive that you know what you earn.

You’re “not a saver type”… then for God’s sake keep your hands off ownership.

Your attitude is more like daycare "I want I want I want".

If you’re serious, then save up equity and check your expenses… not for 3 months but for several years and ONLY THEN do thoughts like “What do I want?” make sense…

"confirmation I received where I only pay in 40€ monthly." So that's 5000 EUR.. that has nothing to do with equity yet. Even if you have a total of..20k..30k EUR, that covers the incidental building costs and it remains a 100% financing. Significant equity should be 50k..100k EUR. 20..30% of the total amount.

Even though Steffen often has a bit of trouble finding the right tone, he is right.
A comparable new building in a comparable location is naturally significantly MORE EXPENSIVE than existing properties.
In addition, new construction almost always ends up being more expensive than initially assumed. Sure, surprises also lurk with used properties, but you have everything right from the start, so overall the cost risk is lower.
I would not even describe the TE’s situation as that bad. It is quite normal to only start thinking about property and family in your mid-twenties (which is actually rather early). Before that, you are first just happy to have your own money and spend it. Of course, there may be exceptions, but I don’t consider it a character flaw if an 18-year-old does not put every cent into a building savings contract.
Once the TE has found out how much equity he has, he can calmly consider whether it even makes sense to acquire property together with his girlfriend at this stage of life. How stable is the whole arrangement?
With one salary alone, you can’t make huge leaps, so depending on the equity, it would probably be more in the direction of a condominium.

That he is now dealing with the topic..is great. No question...but "Zur Zeit beobachten wir Immobilien im Umkreis und ansprechende Häuser/Doppelhaushälfte" sounds more like he also wants to take action "now." I’m saying..save for a few years (really save!, not just 3.50 EUR) and everything looks better.. and then today's prices for existing properties or new builds matter very little..

Well, you can also save with the first property of your own. Maybe something from the existing stock now and then the new build in 10 years?
