I think if the Real Estate Agent is doing a good job then this issue shouldn't be that big or common from your Client. You should do a great job at presenting how the market is performing and detail the absorption rates in your market and what type of offers are getting traction.
It does them ZERO good to submit offers on properties where they have no shot because of the competition. In an environment where the competition is little or none then low ball offers might have a shot after being submitted a few times and sat on over the course of its time spent on the market.... and thats if the property is on the MLS.
Right now....if one is submitting low ball offers then I'd assume the property isn't on the market and the offer is cash with super quick close. We are in a seller's market and in Az at least, stuff under 300k isn't lasting at all.... no way does any low ball offer stand a chance in this market here unless the timing is impeccable and the seller is in a weird situation. Sometimes a flipper might totally mess up their plans and dump an asset for a loss, which means your timing was amazing.
I also didn't read much of this forum so I am sorry if one said something similar already.
