We're looking for offmarket storage & industrial deals and have developed a database of owners and properties, whom we will be calling and visiting. 

It is very common for commercial properties to have underground storage tanks or USTs.

Anything left behind can be placed in storage, sold, or trashed.It sounds like yours is empty and you have confirmation she's living somewhere else.

We've been paying to rent here seasonally for the past few years for about $7500/season (split with my sister-in-law's family), so we know the area super-well.

Hello BP, newbie investor here, and I was curious if there are any seasoned investors or agents who study the market as a whole that would be willing to chat.

And, bam, that shifts her into the same category as seasonal workers and part time workers (there are no more "Stated Income" loans, we have to go off of what HR puts in writing), which in turn triggers the long term 2 year average derived from when HR put her in that part time category, which I'm speculating here may very well have been 5 months ago, or some other period of time less than 2 years ago. 

I’ve heard come tax season, having a software came make it easier on accountants (saving me money).

Hope this helps a bit even though I am not a seasoned investor - yet. 

if she's as amicable as you say she is, then you shouldn't have any issues getting a seasoned attorney's opinion on what's the best course of action for you is right now. 

Here in Florida there is also a pretty ridiculous insurance lead time during hurricane season (they won't issue homeowner's policies when there a tropical storm lurking in the area).2.
