daf bit: Bava Batra 67

[cellio]

The rabbis are discussing things that are and are not automatically included in a sale. If a man sells a house the sale includes the door, a mortar fixed in the ground, and the casing of a handmill, but does not by default include the key, a movable mortar, or the sieve used with the mill. If he sells a courtyard the sale includes the houses, pits, ditches, and caves attached to it, but not movables. (R' Eliezer disagrees, saying he sells only the courtyard.) If he sells an olive press, the sale includes certain parts but not others. (My knowledge of olive presses is inadequate.) In all of these cases, however, if he says "I sell you this (whatever) and all its contents", the sale includes all those items that would otherwise have been excluded. (65a-b, 67a-b)

When I bought my first house I learned that if the contract doesn't specify certain things, they're not included -- even if they seem to "go" with the house, like window blinds. This seems to be like that. (Keys are automatically included in my experience, though.)
