Just regular due diligence?  

Seems silly not to have a regular maintenance item rolled into your monthly fee.Maybe they just discovered for the first time that it needed to be done and wanted to do it ASAP due to the fire hazard.It's a good issue to raise at the budget meetings.Bob

And even if I can open a Solo 401K with that low amount, I heard that if I stop making money in my LLC or close my LLC you have to close your Solo 401K and transfer everything into a regular 401K.

Even with a management company, visit your properties regularly if at all possible.

If you are considering it more for regular life benefit then I say go for it, knowing that it is the primary reason and anything you get from the investment part is just a bonus. 

You are not able to charge for regular wear and tear, so unless it's a real damage you just need to pay for it. 

If investors get the sense that your serious(regular posts/comments) they are more likely to work with you.  

I do not do wholesaling, but regularly connect with wholesalers in the Chicago market.  

I love investing in Ohio  its a great market thought do more in Toledo then Cleveland take regular trips there over the years have built great teams on the ground  which makes all the difference.. recently expanded to Kansas city  and am happy there to but teams on the ground that you can trust is the key to doing out of area investing

I might one day invest out of state, but it would be a location that I would regularly visit.
