Condominium acquisition costs

Hello everyone,

I am considering buying a condominium. Unfortunately, I have little personal experience with this.

Briefly about my situation:
At the moment, I still live with my parents and have about 30 m² for myself there.
Since I am employed, I would like to move closer to my workplace. Ideally, I would finance the apartment entirely with equity. Or does partial external financing make more sense given the current interest rate environment?

My question is:
What acquisition costs should I expect for a 30-40 m² apartment? The location should definitely be rather rural, if possible near Rheda-Wiedenbrück/Gütersloh. The condition does not have to be perfect; I am quite willing to invest some work myself. The floor is basically indifferent to me, preferably basement. But an attic would also be okay with appropriate insulation. It can also be a former social housing unit or a foreclosure. A former fellow student of mine is a civil engineer and would look at the apartment with me in advance.
Before the purchase, I would also seek legal advice to have the purchase contract etc. checked.
Is it possible to make any forecast on how the housing market will develop? Buy now or wait? Are there seasonal effects that influence the price? Buy through an agent or privately? What pitfalls should definitely be avoided?

Thank you all in advance!

Then the first question: What equity is available? What is the income situation?

A question beforehand...

do you want to write a theoretical study or buy an apartment.

The introduction suggests the latter to me, however, I would expect the questions more in a thesis than in the apartment search.

I can answer one thing for you: If the expected return on equity in the next 10-20 years is higher than the current loan interest rates, financing is worthwhile. Otherwise not. For tax purposes, you have no advantage from financing with owner-occupancy.

What happens if you feed Immoscout with your wishes?

In addition to the purchase price, you will probably have 8% (without broker) to 12% (with broker) incidental purchase costs. On top of that, the renovation/refurbishment costs.

Thank you first of all for the answers. : Liquid funds of about €15,000 are available. I currently have TVL-E10. With my tax class, about €1900 comes out. No, it is indeed a serious undertaking. My studies were not that long ago, so maybe the wording was unconscious. I have not yet used Immoscout. But I will definitely catch up on that.

Thank you first of all for the answers.

....
I haven’t looked at Immoscout yet. But I will definitely make up for that

Oops, when I had the desire for a change of location, the first thing I did was to check the various portals every day for offers and their prices. I think I’m not alone in that.
And then many of your questions will also be answered,

Liquid funds are needed for incidental purchase costs on a sale price of €100,000. Renovation costs must also be added.

You will probably not get financing for your wish for suspicious or dilapidated properties.

Foreclosures can rarely be viewed and inspected from the inside.

To be honest, I don’t know what you expect to get in terms of living space with €15,000 of equity? I probably wouldn’t want to invest a single euro in a wreck property.

Thank you for the tips :) Can anyone else say something about the legal aspects?
