Want to buy a new home this Diwali? Then don't go for a house that is unfinished, warn experts in the realty sector. The global financial crisis has left builders with little money and they are struggling to finish off even the half-finished projects, let alone going for new ones, according to industry analysts. Experts warn that the financial strain on realtors is causing indefinite delays in the completion of many projects. 'Those who intend to buy property should go for only completed flats. It'll be too risky to buy properties under construction," said an analyst with a foreign brokerage. He cited the example of a Mumbai-based realtor whose high-end residential project in Lower Parel, one of the city's commercial hubs, was to be completed in 2006 but has now been delayed till 2009. Uncertainty looms large over whether even this deadline will be met, he said. This isn't an isolated case. Analysts say delays of three to four years are likely in under-construction projects.
