Sunteck Realty Limited (BSE:512179) said it is looking to scale up its commercial portfolio. "Currently, 80% of our business interest is from residential segment. The commercial market as a category is showing recovery in prices and we see opportunity in developing it," SRL's Chairman and Managing Director Kamal Khetan told BusinessLine. "There is uptake on the demand side both in the sale and rental. We expect commercial real estate to be about 40%-50% of our total real portfolio in next three to four years," he said, adding that once the company has a comprehensive portfolio in the commercial segment, it may also look at a REIT (Real Estate Investment Trust) listing. "We are developing a portfolio. We may look at REIT listings in three to four years depending on our cash flows," he added.
