When I went to put in a tender on a place at the start of the year we were told that there were several other offers. It sat on the market for another 6 months after the closing date so I doubt anyone actually followed through (we didn't).

Don't put too much into what the RE said because they work for the seller to get the best price. However, 60k is less than half of what it was previously listed for. Perhaps go middle ground and offer $70k?

Good luck
