No dishwasher, no garbage disposal

[Bienes Raices]

And no refrigerator either but I know what to do about that...

Are there any issues with putting or connecting a freestanding dishwasher adjacent to the cabinets? There is no "space" where the new dishwasher would go in the cabinets, so I would just have to put it on the floor.
Also, is the lack of a garbage disposal a big deal when trying to attract tenants? This is a mid to lower income neighborhood, if that helps.
