Perfect example, and this guy had done market research on a $4 saving yet people will not look at comparable sales on 500k purchase and blame everyone else but themselves....
Surprising that people will spend next to no time researching about a property and value but will spend 2 weeks researching and comparing TVs and their price to save $100.
Offer what you are willing to pay, if you offer less than what you are willing to offer be prepared to lose it.
Regarding the offers under $699k, should also contact the agent and say but I want to offer $700k haha :D
