We used I Sold My House.com for a piece of land and got lucky. We went this route because the realtor that we interviewed seemed overly nervous about a property on The Broads. If this person was conveying this to two people that are blissfully happy being out here, how could I trust that this person would represent us well?
I Sold My House offers, for a fee, MLS Listing. We agreed to give half commission to any realtor that brought a buyer. Bummer friends of ours called a local realtor that appeared like they were the listing agent for our lot.

We could have saved the whole commission.
If I Sold My House hadn't worked, the next realtor that I would have called is Roy Sanborn. His blogs here at Winnipesaukee.com are super informative, showing how knowledgable he is. He does handle island sales.
