House prices won't fall – and could soar 15% when mortgage rates drop, says 'Shark Tank' investor Barbara Corcoran

• Home prices won't drop, and could surge 15% once mortgage rates fall, Barbara Corcoran says.
• There's a shortage of homes for sale as people don't want to give up their cheap mortgage rates.
• The housing market is in good shape, and buyers will pounce once rates drop, Corcoran says.

Home prices won't fall, and could jump as much as 15% once mortgage rates drop, Barbara Corcoran predicts.

"I can tell you this – house prices are not going to come down," the "Shark Tank" investor and real-estate tycoon told "Good Morning America" this week.
