West Coast realtors [British Columbia, Canada] -- they got a habit of creating MULTI-offers on a piece of real estate.
how do they do it ?
a) they place on MLS that the owner/s will only look at offers on a certain date which pits realtors against realtors [and their clients]
and/or...
b) if there are, let's say -- 3 pieces of properties on sale in the same block for let's say...$430K -- the new listing would be placed UNDER $400 [$399K] and of course this wets the unsuspecting buyers to go ABOVE the asking price.
