A lot of knowledgeable persons are contributors of this site. Mr. SubCon has put very convincing comments for commercial investments in future regarding on line shopping. Still commercial is sought investment. My view is that there must be one ratio or multiplying factor between commercial and residential which is KPI (key performance indicator). Say 5. If commercial is available less than 5 times residential. It must be bought. If it is available more than that then residential should be bought. Comments from all gurus specially Subcon, Shah, Ahmet Kildier, Jameel Moghal, Habib, Yahya are requested.
