Does Blk 421B Northshore Dr have a PriceVero rating?
Yes — a block rating of A on an A–E scale, measured within HDB resales only and never compared with a condominium. Whether a particular price is low, in line or high is a separate reading, and it depends on the price, which only exists when you name it.
What about Cash Over Valuation (COV) at Blk 421B Northshore 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 transacted resales, which is the evidence available before the OTP.

The nearest HDB car park to Blk 421B Northshore Dr is a basement car park with 4 decks. Short-term parking: Whole day. Free parking: No. Night parking: Yes. Published by HDB under the Singapore Open Data Licence.
