Hey All.

Has anyone found any houses, shacks or rooms the player can buy like the houses in Fallout 3?

found 3 so far

1. Caesears legion safehouse
2. Followers of the apocolypse safehouse
3. lucky 38 presidential suite (with upgrades)

Can you get anyone of those Early in the game?

nope

Theyre given to you by the factions

i havent unlocked FOA or CLs safehouses i just found them by wandering around. Safehouses need keys which are given to you by the factions who own them.

lucky38 on the otherhand.. you get by progressing through the main story

I've Got The Novac Motel Room Not Sure If It'll Let you keep your ammo and stuff safely in there, There is a safe there though.

You Can get it Kind of early if you follow the main quest till you end up in novac and you don't have to pay for it if the towns people like you enough

Theres a thread in the spoiler section that goes into more detail on this.
