Yes — a block rating of C 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 423 Choa Chu Kang Ave 4?
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.
