It varies on an individual sale level, any appliances can be included when selling a house, but other than built in ones (which refrigerators usually aren't) its hit or miss for new houses that aren't models, and for existing houses it really depends on the seller (owner occupied, they may want to take it with them, depending on the circumstances where they are moving, as it previously an equipped rental, then they’ll more likely offer to include all the major appliances, etc.)—and buyer (may prefer unwanted personal property be removed prior to move jn rather than included, if they want to buy something new that suits them or being their current unit.)
