Everybody knows its cheaper to buy finished (generally speaking) vs build from scratch.
Lot of money/time already spent on this, and would be perfect fit for someone wanting to do ground up resto/build.
The crowd on here generally either wants something complete or wants to put their own sweat equity into it, which is what makes this listing challenging as it doesnt fit either of those. To the right buyer this is a good deal, just have to find the right buyer. It only takes one.
Best of luck, hope you are finally able to find the right buyer. Going on ebay i think will give it good visibility for broader audience, and hopefully translates to hammer strike at the end.
