looney

I am currently owning a 5rm flat..and cos of my kids..i need to move to somewhere near my parent place..bt cos my parent is staying near to the central..therefore..i can only afford a 4rm flat at tt area.. i understand tt i m nt eligible for hdb loan unless i pay a 45k levy to hdb only then i will be eligible for hdb loan... Have been hunting a flat near tt area for mths..n finally i hv found someone at tt area selling...Bt when i went to the bank to ask for the bridging loan thingy.. the bank personal say tt unless i sell my current property then i will be eligible to get a bridging loan from them....else i gt to pay a 15% (either cpf/cash)....bt i do nt hv tt much in my cpf...cos my usual practise was to clear one lump sum of my hdb loan once a year... also learn tt i need a 5% cash to pay to hdb too.. Anyone here can advise....is there a way tt i buy 1st then sell off my current unit..Thanks
