Q: Hi, i am about to buy a 3 BHK, in Shivkala Charms.But i have heard the project has been delayed for more then couple of years nw.Even i went to the site thrice, but i saw no development or progress in the construction.I have been told tht i will get the possession by dec'10.I don't the builder will be able to fulfill the commitmnt.evn my home loan is approved.I don't know wht to do.Now at the time of signing the agreement i have been told tht i will be allocate a different flat, thn wht i was promised.The reason given is that the actual owner has not still not cleared the loan with LIC, with whom it is mortgage.I have been told tht i will get the same flat as i was promised but after 3 or 4 months, as the mortgage from the owner needs to been cleared n then the flat transferd in my name.till thn the builder will give me an alternate flat....this seems really fishy..please advise.
