Good choice to choose a FH condo near Bishan, especially is near to the North-East line.
There are not much FH property close to Bishan. Boonview, Marymount View are 2 that is very near to MRT, walking distance. Another one is brand new, just beside RJC and the MRT station.
Please drop me an email or you can call me directly for a detailed discussion. Let me know your plan and requirement and I could work out some viewing for you.
Thanks & Best Regards
