Henderson county illinois | What is a 3 year old barn worth? Tunnel ventilated, Lester building package, feed to finish barn, already has a contract in place at 41$ a pig space. With new barn prices going up everyday,I am unsure on how to value the barn. Just the building was 580,000 3 years ago but I have been quoted 750 to 800g for just a new building now. I am thinking it is worth 750ish since it is turn key. I appreciate any feedback. I am looking to buy this building from a family member who wants to sell. |
