Had a realtor doing that to me and I walked (ok I actually was a chicken, ’cause she was really nice, just really annoying….told her we gave up the home search and were going to rent).
Did my own research and found my house within my budget, in my desired neighborhood, with no help from a realtor. Really not that hard with the internet and iphone apps, I found stalking neighborhoods with my iphone and dog (so I looked innocent) were particularly useful. I used the listing agent and he got both sides of the deal. Served me well as there were several offers and he basically told me what my “highest and best” should be and we won.
