Sir, this is very common in Delhi NCR and has been in vogue for 3 years now.One variant of scheme very popular with investors works like this.One books a flat by paying 10% and balance 90% on possession.Loan is on the person but is guaranteed by the builder and he pays all the EMIs.On possession you can sell back at 10% profit or at market selling price whichever is higher or take possession..The only cliche is that builder should not go bankrupt.Reputed builders like Godrej Raheja etc are offering such schemes.
Even better schemes are for end users in RTM flats.Fully furnished flats with complete woodwork in all rooms,Geysers in toilets,complete lighting and fans installed, ACs in all rooms complete modular kitchen with chimney.They even throw in a washing machine.NO Registration charges, free parking slots,free club membership,and one year free maintenance and to top it all selling price of flat is basic BSP which is cheaper than resale value.On top of that these flats are eligible for PMAY.What else one can wish for.I have suggested all friends who dont have a dwelling to have a hard look at these options.
