Zhuhai prime condo is 1/5 of psf of Hong Kong NT(East) and NT (West) condo
JB prime should therefore be 1/5 psf of Woodlands
say Woodlands is SGD 1000psf then JB prime should be 200psf = RM500psf so RM 500k for 1000sqft home
other than freehold landed vs 70y leasehold condo in Zhuhai, the price gap is sama sama, I would say just buy something in case you cannot retire in Singapore then rent out everything here and go stay in JB (by then crime issue should be solved liao)
Ride at your own risk !!!
