Good investment option

I invested in a Wohnimmobilien project. The process was straightforward, and the interface was easy to use. Everything worked as expected. No issues so far.

Smooth experience with Projektentwicklung

I recently invested in a Projektentwicklung through zinsbaustein. The online registration was quick, taking about 10 minutes to set up my account. Funding my investment was simple too, and the funds were visible in my dashboard within two business days. The communication regarding the project updates has been consistent and clear. I had one question about the Steuerbescheinigungen and used their contact form; got a helpful response in less than 24 hours. The investment dashboard itself is well-organized, showing my earnings and project status without being overly complicated. It feels like a solid platform for these types of investments.

Decent value for first-time investor

As a first-time investor, I was looking for something with a good return that wasn't too complicated. I chose a Neubauprojekt. The minimum investment was reasonable, and I noticed they had a Willkommensbonus for new customers, which was a nice extra. It wasn't a huge amount, but every bit helps when you're starting out. The expected interest rate seemed competitive compared to what I saw elsewhere. I'm keeping an eye on it, but for the initial outlay and the bonus, it felt like a worthwhile venture. The overall value was there for me.

Anyone know if they have any new customer deals right now? Trying to get a little extra if I sign up.

D Dana 1 month ago
Definitely check, they often have like a 25-100 Euro bonus for new sign-ups. I got one when I first joined.

They almost always have some kind of welcome bonus or starting credit. Look for a field during registration or checkout where you can enter a code.

What kind of interest rates are we talking about here? Roughly, what's the average people get?

T Troy N. 1 month ago
It varies project to project, but I've seen things from like 4% up to 7% or 8%.

The average yield is usually in the range of 5-7% per annum, sometimes even higher for specific projects. It's fixed, which is nice.

Is this whole crowdinvesting thing even safe? What if the developer goes bust?

P Paula W. 2 months ago
It's never 100% risk-free, it's investing after all. But they do a lot of due diligence on the projects.

They have a pretty thorough project selection process, and they mention what happens if a developer faces insolvency in their FAQs. It's an subordinated loan, so there are risks, but they're transparent about it.

I got a referral code from a friend. Where do I even put that in when I'm signing up?

M Mark 1 month ago
Should be a field for 'Aktionscode' or 'Referral Code' during the registration process, or maybe when you make your first investment.

Look for it during the account creation process, usually on one of the first few steps. Or, sometimes it's applied when you actually make your initial investment, in the checkout flow for that specific project.

I'm looking at Zinsbaustein and Exporo. Any thoughts on how they compare or which one might be better?

G Greg T. 2 months ago
I've used both, Zinsbaustein feels a bit more curated in their projects, but Exporo sometimes has more variety. Depends what you're looking for.

They're similar, but Zinsbaustein focuses heavily on the German market and often has slightly different project types or structures. It's worth checking both platforms to see which projects appeal to you more at any given time.
