If the line is ABS, I'd just leave it and have it cleaned periodically.Hi Bruce, It was built in 72’ and may have some roots pushing it up.  

However, there are a few things to consider, and it would be in your best interest to dig a little further in my opinion (if you haven't already).First, were you ever aware of any "out of the norm / significant" structural issues with this wall, the basement / foundation in the area of this wall, or any issues with the tree roots under the slab or hitting your dwelling in any significant way? 

There really needs to be a more complete fix for this which may entail digging up the pesky weeds deep down to get the roots, adding more topsoil, and sodding.

If you close on the property and then discover the roof is leaking, the main sewer line is nothing but tree roots, really any major expense, that can easily put a borrower in a position where they do not have enough actual cash to solve the problem, so the property loses value due to deferred maintenance, or the borrower digs themselves into more debt, making it even harder to get another loan to cash me out of the equation at that upper 20% of equity.

@Ashley Marrazzo used to crew and run boats so rooting for you.

Look no further than Clintons CRA to find the root of this

Is it just to be a pain or is there a deeper rooted issue causing some uncertainty. 

Maybe do a sewer cam inspection if it hasn't been done, and ask renters what problems they have (ie Hot water lasts 5 minutes, no heat in Unit B bedroom, etc...)Job A Problems$$$/How long to fix: inward movement on the foundation with masonry (tree roots?

ADK REI (my husband and my self)) run a meet up the first Thursday of every month at common roots brewery private event room in south glens falls from 7-9.

I suggest asking yourself "why" 5 times to get to the root of the desire to invest.
