That's it really.
When we first got our estate agent round to do a valuation, he talked the talked.
However, one thing he did say was that he didn't think Rightmove was the best portal to use. He said used it only as a last resort, and used other portals first, because "People just browsing use Rightmove, but actual serious buyers search on Zoopla and OntheMarket, etc." Both DH and I queried this at the time, as we thought Rightmove was more popular. But the EA won is over (as well as assuring is that he already had plenty of people on his books that he would call); we trusted him, as we thought the EA knew best (naive yes, but this is our first house selling).
Anyway, we're now week number 4 into selling, and we have put our feet down and insisted he add our listing onto Rightmove (which he originally told us he would do after 3/4 weeks, as the last resort, so this is what he agreed with us anyway).
During this time, we have had only one viewing last week. So we went live on Rightmove today.
It just made me think/wonder how popular Rightmove is. We are not proceed able at the moment, but we are/will be serious buyers, and have been looking on selling sites. RM just hands down seems to have the most listings, even all the listings of Zoopla that I've seen have also been on RM.
