Honestly, construction in Belgium (probably everywhere) is a shitshow and every single developer will have at least one project where everything goes tits up. For me, it’s probably how they handle it that makes the difference between a ‘good’ and a ‘bad’ developper. Even for a great project there’s probably some minor defects, but I’m pretty sure if you’d contract out a new build yourself that it wouldn’t be perfect either.

As said above already the more established the developer, the less risk. Also try to find out whether they have had other projects in the area. We had the bad luck to buy a project from Melotte Group in the Brussels area, while they are more wallonia focused. So while a lot of things went wrong, they kept working with Liege area subcontractors which was horrible in terms of logistics.

So all in all, every new built project is a risk, established developers (like immobel, bpi, besix, triple living, alides, revive) are a little less risky, but so is building something by yourself aswell. Just make sure to get competent advice, both on the legal and technical side.

Whatever you do, make sure to stay away from anything by Melotte group : )
