Durain is spot on. It would make more sense for you to live close to your daughter's new school which will be around the Upper Serangoon Road area of Singapore. You will get far more bang for your buck accomodation-wise and with the Northe East Line MRT fairly close by, you can take the train direct to Harbourfront in about 20 mins.
Alternatively, there is a large Indian expat community in the East Coast, in and around Mountbatten Road, Marine Parade and Tanjong Rhu. Thus there would be regukar school buses to the Indian School from there.
If your heart is set on living close to work in Harbourfront, then the closest private
condominium that will most likely fit your budget is Harbourlights. You can literally stroll to Harbourfront in about 3 minutes there. The disadvantage is that it is right next to the very busy Telok Blangah Road and a big expressway viaduct. One bus stop further west is the Caribbean but this
condo is probably out of your price range. Two more bus stops away you will have the choice of either Harbourview Towers or Fairways. Harbourview Towers' 2-bedroom apartments should be within your price range and the condo is very nice. (I lived there for 2 years.) But the 2nd bedroom is very small... Next door to Harbourview Towers, Fairways has been sold to a developer for enbloc development but because of the market situation the developer is leasing out the apartments on a short/medium term lease. Less than 10 minutes by bus further west you will find lots of other private apartment options.
If you instead opt for 'public housing' or HDB flats, you should be able to rent a 5-room apartment (3 bedrooms plus livingroom/diningroom plus kitchen) for about $2,500 in and arund the Telok Blangah Drive/Heights area, which is just behind Harbourview Towers.
