Starter house

A starter house is a house that can be bought and (if necessary) furnished for less than 20,000 Simoleons, as that's what newly created Create-A-Sim Sim families have without cheating, expect after some newer expansion packs, the money got after making a family in CAS depends on how big the family is.

Even if it's not necessary to move a Sim into a lot in order to build on it, it may be helpful to do so when constructing a starter house, so that you won't be tempted to go over. Starting with The Sims 2: Nightlife, you can "View Lot Info" to see the total lot value.
