Appraisal nightmare could lose deal in Montana

[Charles Tucker Kimbrough]

I have a deal that may be in jeopardy in Polson MT.  We have been through 2 months of appraisals with 2 different appraisers both of which have refused to appraise our property because they claim that there is a lack of comparable properties in the area.  The closing is 2 weeks away and I'm wondering if anyone has dealt something similar to this before and what they did to solve the problem?  I also wonder if anyone here might be able to suggest a lending option in that area that would not require an appraisal?
