First off, thank you both for the replies. Perhaps I was too harsh about the condition. It is an older facility built maybe 25 years ago but it isn't about to fall down currently. it just something I need to consider if I intend to keep this long term. That being said it is absolutely lacking in maintenance and likely only the necessary things have ever been addressed. Hearing that it should last is a relief but I do know a contractor that would take a look if I asked him so perhaps that is a route I will take.
As for expansion on the land there isn't enough land to double the size of the facility unfortunately. There is enough to add maybe a third building with smaller units of around 45' rather than 60' or even outdoor overhead covered storage as there is a bit of that in this area already. I think a fully enclosed unit might be best though. But that is a consideration that I could potentially build that new unit move everyone out of one of the buildings while I upgrade it. That is a potentially viable plan so thank you for that Greg. Also, I figured I was way overestimating the insurance so that just makes this deal make even more sense.
Michael, thanks for the input. I will definitely check out your blog on here to get a bit more info about this industry. I do have one question though. I know there are many factors to this but how long would you estimate the pressure treated lumber typically does last in the ground like that? 50 years? Longer? Ideally I would buy and hold this property as a way to raise capital to expand my portfolio as time goes on rather than sell it in the future.
