I see the sale of your property in two areas:
First, you need to find a Realtor that has experience marketing homes similar to yours. The number of buyers that are looking for this home is small compared to "standard homes" so you need a Realtor with a marketing plan with maximum exposure, a Realtor that can attract buyers to properties and more importantly, has excellent relationships with other Realtors who have buyers.
Second, when you have an older home that needs work, you do have a couple of options:
1. Sell as it...and get less, take longer to market...it may never sell.
2. Clean it out. An old home that is CLEAN will sell faster for more money that the same home filled with cluttter and filth.
3. Clean it, do SOME repairs and painting, particularly the FRONT of the home (curb appeal and entry) to give the buyers a glimpse of what it could be like. Some light staging in those areas, coupled with professional photography, will help a great deal.
If you need a top agent to interview contact me via my Trulia profile and I would be happy to arrange it.
Good luck. Sounds like a neat home.
