Hi ICE,
Refering to this link "http://www.hdb.gov.sg/fi10/fi10321p.nsf/w/BuyingNewFlatEligibilitytobuynewHDBflat?OpenDocument" I believe you will be ineligible to purchase a new HDB direct from HDB.
However, you may still purchase a resale HDB from the open market and you'll have to sell your existing condo within 6 months from the completion of your HDB purchase. Should you need to utilise the proceeds from the sales of your condo for the purchase, timing is critical.
Perhaps we can have a more detailed discussion for your plans such that I am able to advise better.
