Newbie looking for some insight and wisdom on clutter

[Tyler Kivland]

I recently purchased a duplex on a fairly nice street and inherited the tenants from the previous owner. One of those tenants experienced some difficulty from an insurance scam and lost his home of 15 years as a result. It was quite the downsize which has resulted in him living among boxes for three months and counting. That part I don't mind so much but his stuff is also outside of the house. It's stacked "nicely" but frankly, it's obviously clutter and I don't feel that its fair to neighbors on the street let alone my other tenant. 

After asking both of my tenants to please help by cleaning up their items outside and even mentioning that I would help with some of the larger items and/or items that were not theirs, I got this email back...

A wise man once said: "There's what's written, and then there's what's reasonable. Whenever possible, go with what's reasonable."

What's written comes from a boilerplate lease that I signed with the previous owners. Owners who left dirty shelves and gaps around the doors. Given their approach, reading every clause in this lease and negotiating what concerned me did not seem productive. But I understand, it's the document we have.

Thoughts? 

The term "firm but fair" keeps going through my head. On one hand, I didn't make him sign the previous lease and, although it is riddled with holes, it's all we have and it DOES state that tenants will keep the exterior clean and clear of clutter. On the other hand, is this a battle worth fighting right now for someone who is clearly struggling? So far, he's a pain but he pays his rent. 

All help is appreciated and valued. Thanks!
