Buyers pay for checks and monitoring. Developers never pay Kolaboro: the evidence sets every Score. Agents never take money from developers.

Is Kolaboro a lawyer or a notary?

No. Kolaboro checks facts in documents and official registers and tells you what it found; checks on site by local agents are being set up. For legal advice and to sign, use an independent lawyer or notary; we can tell you what to ask them.

Do you hold my money?

Not yet: escrow is not offered today, and milestone escrow with licensed partners is on our roadmap. The plan is that a local agent confirms each milestone on site before you pay; those site visits are being set up and we are recruiting our first agents.

In any country. The desk review and the official-register lookups run online for off-plan projects anywhere. On-site visits by a local agent in the project's country are being set up: we are recruiting our first agents. When you book, we confirm an agent for your location before any work starts, and if we can't take your case you get a full refund.

How do you decide "go" or "hold"?

Nine checks, from land title to realistic promises. A red flag on title, permits or progress means "hold" until it is fixed, and every finding links to its evidence. The full method is public.

Can a developer influence a report?

Only with evidence. Developers can send documents and reply, but never pay us. Where something can't be verified, the report says so instead of guessing.

What if I already bought?

That's when monitoring matters most. Today we can check the registers, the permits and the developer's record before your next payment; checks of construction progress on site are being set up.

Delivery forecast: Osaka

Estimate from the dated handover history of comparable projects (Kaplan-Meier), not a finding about this one.

Not enough data for Osaka yet: 0 projects past their first promised handover and 0 handovers recorded. We show an estimate once a group has 20 projects and 5 handovers.

For context only, all markets pooled: 120 projects whose first promised handover has passed; 19 recorded as handed over. This is not an estimate for Osaka. Kolaboro promise history, 5 Nov 2026

Handed over by	Estimated chance	95% range
the first promised date	10%	4% - 15%
6 months after it	14%	7% - 21%
12 months after it	18%	10% - 26%
18 months after it	18%	10% - 26%
24 months after it	18%	10% - 26%

Limitation: most projects we track are still on sale, so projects that handed over on time before we started tracking are under-represented. The estimate is likely to be too low.
