Something I'd suggest is being a parasite off the commercial businesses and pretend the retail market doesn't exist.

You can't buy a residential clothes washer designed to last longer than five years; laundromats won't tolerate that; solution, pretend Home Depot doesn't exist and buy a Speed Queen that your kids can probably inherit.

An interesting side effect is residential / contractors special type stuff has a very low initial cost of purchase but overall lifetime cost is always lower for commercial grade stuff; this makes sense, if it was cheaper to buy residential garbage the beancounters would force it to officially be commercial...
