Does Blk 509 West Coast Dr have a PriceVero rating?

Yes — a block rating of D on an A–E scale, measured within HDB resales only and never compared with a condominium. The 0–100 rating for a specific flat depends on its price, which only exists when you name it.

What about Cash Over Valuation (COV) at Blk 509 West Coast Dr?

COV is the amount a buyer pays above HDB's official valuation — and that valuation is only issued after an Option to Purchase is granted, so nobody can know COV in advance. PriceVero does not predict valuations or COV. It rates a price against this block's lodged resales, which is the evidence available before the OTP.
