Up front purchase price doesn't matter since it amortizes out over the life of the machine. All you're doing is paying up front for the downtime for service it won't need compared to cheaper consumer grade stuff.

I used to do facilities maintenance for a hotel. We weren't space constrained in terms of laundry so we ran a fleet of cheapo consumer machines. One was down at any given time but it was still cheaper than introducing fewer high grade commercial machines. We had some commercial stuff that was ancient and still worked. Didn't break much less but it was easier to work on (primarily because age) when it did.

Obviously if you want to minimize downtime because you're an absentee landlord who has to pay a PM company to do a visit every time a lid sensor fucks off then having commercial machines makes sense. In terms of dollars per load the cheap consumer stuff is in fact cheaper, assuming you don't live in a regulatory capture hellscape where you are supposed to have a plumber connect your drains and gas lines (or are willing to ignore those rules).

The commercial grade machines I've dealt with in SF apartment and condo buildings were worse overall than the non-commercial ones in Victorians and townhomes. They could take larger loads and washed/dried faster, but they had worse sensors, distributed detergent worse, ran too hot for drying, and slightly damaged some of my clothes.
