Log homes can and do hold their value and sometimes even increase in value as long as you properly maintain the log home and care for it.
Just don't let the log home run down just like any other home and you'll be able to easily sell the log home to someone for what you paid for it or even more in some cases.
I had a log home that I lived in for awhile until I had to move because of a job that moved to another state and I had to move along with the job because I need that job.
I then went to sell the log home and it actually sold for $20,000.00 more than what I paid to have it built so I actually profited from the sell of the log home.
Then I had another nice log home built on my current property and had some money leftover.
So just maintain the log home and care for it properly and the log home will continue to hold it's value and also log home buyers are usually pretty much more educated when it comes to buying homes because they're desiring a log home.
