I hate it when agents pull that duck move.
Is there a third-party property
agent you can deal with aside from Far East (being the developer of the place)? For starters you can check this forum's property segment and see if someone is representing Woodhaven.
Otherwise, it is not necessary to live in Woodlands. A good compromise would be staying at these areas for expat-friendly touch (assuming you're using the school's bus service, and not own public transport system):
1. Upper Thomson Road, around Thomson Plaza
2. Sembawang Road, around Sembawang Shopping Centre
3. Hume/Hillview area at the north of Bukit Batok
4. Upper Bukit Timah Road (might be a little bit too far but definitely nearer if compared to distance from Orchard).
Where do you/wife work? Would moving to Woodlands affect your commute to work?
