STR appraised $120,000 less than offer

[Jason Warner]

Hello friends,

I am currently under contract with my first STR in northern Michigan. The location we chose will be a 4 season rental (skiing, snowmobiling, boating, fishing, golfing) with lake/dock access. Our offer was $260,000 (which we thought was close to value) but the appraisal came back at $140,000! What do we do?? A bit of a red flag I suppose.. The previous owners have had it for only months and they paid $220,000. There are comps in the $220's but 140k is still quite far from that even!
I think I’m dealing with a management company, is there a chance they would like to off load this property before year end even at a loss to avoid paying taxes and such? 
Thanks in advance for your advice!

everyone is speculating about the appraiser here without enough info.

if the seller is basing the sale price on the STR income, and the appraiser is basing the appraisal on comps, there's no contradiction...
