Start a 6 player local multiplayer game using 1 controller. All human, no AI.
When the game starts, auction every property a player lands on and win it with your player.
During your turn add 4 houses to every property you own. (You have to own a full color set in order to buy a house.)
If you run out of money, just trade with another player. Give M1 and take everything you need from the other player.
Once you buy and place down 32 houses, which is 8 properties that have 4 houses each on them, you will get the achievement.
