Burglary

About
Burglary missions are side missions in San Andreas. They are first introduced in a mission "Home Invasion". You must obtain a vehicle called Boxville Black and wait for the night (8pm). Then you'll be able to go inside other houses and steal. Burglary missions are a good way of obtaining money. There is no limit for burglary missions, you can do them every night.

It is better to rob houses in a wealthy areas like Vinewood that those in Ganton or Jefferson because they have more items.

Tips
Noise

Noise isn't a problem at all. Buy a silenced 9mm pistol (first you must unlock it in a mission) and shoot the occupants of the house in the head while sleeping. Then you can move around faster.

Time

Find a house that you want to rob, park in front of it and wait for the time to hit 8pm instead of waiting till 8pm and then going in action.

Items

Every item is worth the same amount of money so it doesn't matter which one you are going to steal.
