Putting in offers

[Dondi Sanchez]

my wife and I found a vacation/ over night rental cabin in Pigeon Forge TN. What there asking is below market value. I had to get my numbers from square footage because comps in an area like that is not easy and there hasn't been a sale since the beginning of the year. And input would help. The average is 110.00 a square foot and there selling for 80 a square foot. Plus all furniture is included. They were asking 199,900 I offered to 185,000.00 it has been on the market a whole and I think they put it low to start getting people interests again because it was well over priced before. The agent told me another person put in an offer as well. I thought it was odd since it's been on the market a while, I didn't know if I was getting squeezed. So I up offer to 187,900. Now there telling me that they want is to give us our best bid without a counter offer from them. Does this sound fishy to anyone? Any advice would help

Thanks in advance
