Just going by the averages, 480/sq.ft. is way, way beyond the going rate for any part of this country at this stage, including D4. Especially for a very average 3-bed semi. You’d have to be bonkers to pay this.
Its on the east side of the road so the garden has a north east aspect. On the plus side the gardens on the other side of the road back on to the Dart line. This road had flooding in 1986 with Hurricane Charlie.
I don’t think it’s a great road. It’s a bit pokey and parking is a nightmare. The main thing that put me off is the fact of it being a terrace and not garage so gives you little or no scope to extend or improve it. There was one across the road on the market at 550k for a very long time recently. It was nicer, had good kitchen extention, beter orientation and a garage at the back. also think it will go for close to asking but I won’t be bidding.
