Government Guidance Rate

Maharashtra registration department

In Maharashtra it’s called the ready reckoner rate.

No government guidance rate is shown for this project.

Mumbai's ready reckoner is addressed by city survey (CTS) number inside a named village, and this filing declares neither — its village field holds a ward or a taluka. Naming one of the zones around it would be a guess, and inside a single division the rates run three-fold.

That is a statement about what Horizon can place — not a sign that no rate exists, and not a signal about the project.

Complaints & litigation

MahaRERA · public record

Complaints register

None on record with MahaRERA against this project.

Only disputes escalated to the authority appear on the record — a private disagreement never filed here would not. A count from the public record, not a verdict.

What the builder declared

Declared to MahaRERA

Litigation: None declared to MahaRERA

The builder's own declaration at registration — not a court's or MahaRERA's finding. A flagged line is worth checking with MahaRERA.

Not a verdict. A complaint can be dismissed and a case can be won; an order can be appealed.

Not a clean bill. An empty record means nothing was filed with MahaRERA, or that this register doesn’t publish it — never that nothing happened.

What this record cannot tell you

Build quality — no filing records how well it was actually built.
Private disputes — only complaints escalated to the authority appear here.
What it will be worth — the record is the past; it does not price the future.
