When does it make sense to pursue a business with relatively low margins?

I've reviewed a number of LMM deals in the past few months where the business seems fundamentally strong: long history, outstanding customer reviews / reputation, well-known brand in the community. However, SDE margin leaves little room for error for an independent searcher, even leaving in generous add-backs (pre-LOI).

In the spirit of NOT chasing the proverbial unicorn, when does it make sense to pursue this type of deal. Here are some of the items on my list:

- Seller has taken their foot off the gas (low working hrs).

- Obvious efficiencies: founder-led business without any professionalization.

- Seller managing the business to minimize taxes (potential positive in dd?).

- Extensive direct experience in the sector.

- Partner with someone who can visualize realistic improvements.

- Strong preference to operate in that sector or business.


In any case, it seems like a bit of a turnaround scenario, which is not the generally recommended ETA model. But in a world where there are no absolutes or unicorns, I'm trying to keep an open mind.
