Is it better to buy property or not?

It makes no difference. Whether you buy now for 60k and the bank only values it at 30k or you buy later and the bank still values it at only 30k is six of one, half a dozen of the other.

Of course. If the entire project needs 300k, with 60k for the land and 240k for the house, and I have 60k equity, I need a loan of 240k with 60k equity. That's 20%.
If I buy the land now but it is only valued at 30k, I need 240k but only bring 30k. That's 12.5%.

True, but it has nothing to do with whether 60k should flow into the property now or later

Why isn’t this discussion actually happening with EVERY house construction or land purchase? Because the bank usually does consider the purchase price, maybe with a small safety discount. Appraisals are done at most in special cases in the outskirts or similar situations. If he now buys a plot from the municipality in the new development area for 60k, it is worth that much, they don’t start with appraisals there. And if the bank actually does it, of course they also do it when the land is financed together with the house construction.

So, financially it doesn’t matter when you buy the land. The question is whether the land might simply be gone otherwise. If the location suits you, then buy and that’s that.

So in my opinion, you have to buy the property with equity if you want to get reasonable conditions. The bank wants to be first in the land registry.....if Bank A is already registered first on the property and you now want to finance a house on top of that, you will get okay conditions if you have discussed it with Bank A beforehand... But if you want to finance with Bank B, they will not be happy that Bank A is already first in rank... In my opinion, the important thing here is the period of time that passes between buying the property and building the house....we took 1 year until construction began.....

why is it all about the money here and not about the condition of the property and what you can build on it?

I don’t buy a kitchen and then the apartment that fits it

The plot is flat, the development plan has no special requirements. A soil investigation report still needs to be created. For the €60,000 I have already included surveyor, notary, soil investigation report + land transfer tax. We still have about €10,000 left over for things that may come up. Furniture, kitchen, etc. do not need to be newly purchased as everything is in like-new condition and can be transferred to the new house. Ok, I still have to budget a small additional €3,000 for the kitchen for remodeling + 1-2 extra cabinets :-D. The house will also not be particularly large, 120-130m².
