I was wondering if you can get your own house in Fallout: New Vegas like you did in Fallout 3?
There are two 'homes'. When you reach Novac, there is a Motel room you can rent, which is safe to store stuff and rest in, and if you complete the quest One for My Baby by accusing the actual perpetrator, you'll receive it permanently at no charge.
Further along the main quest, once you reach The Strip, you'll be given access to the Presidential Suite at the Lucky 38 Hotel and Casino. This functions more like the house you gained in FO3, in that when you dismiss companions, you can have them wait for you in the Suite, and you can purchase various 'upgrades' to add more style and functionality to the apartment. There are also several mods that add additional crafting resources or other customizations, if you're playing on the PC.
You can use Victor's shack in Good Springs: that's the first house you can get. You've got a bed to sleep in, a sink which is purified, a oven to store your aids, a couple of ammo boxes to store weapons and ammo, and also a desk to store your miscellaneous stuff. It's also free of charge; there's no need to rent a motel room.
Get in a house, kill whoever is in there, and just stash your stuff there.
Kill Victor (you are gonna do it anyway in the storyline, unless you are the kind of guy that does anything you're told and be House's dog) and take his shack.
Also, there are several abandoned places which would do just fine.
There's 2 places that i know of,
the Penthouse Suit inside the Lucky 38 Hotel and Casino provided by Mr House when you meet him, you can customize by buying stuff
The Brotherhood of Steel Safehouse which you get from doing quests for them, since i always opt to not blow them up i have no idea if you still keep it after you get rid of them.
if your on PC there's ofcause Mods, 2 that i use is
Underground Hideout - puts a manhole in Bonnie Springs, you can do a quest to get the key or opt to skip it, inside it has a garden for growing food, water purifier, clean water sources mannequins, weapon and ammo sorter/storage, a teleporter and the terminal inside allow you to get delivery from the Crimson Caravan. you all get this sledge hammer which allows you to move the manhole so it's mobile somewhat.
there is also a setting to use the Reactor which powers the place, having the setting on means every light consumes power and the reactor needs to be refueled with some Isotope which you can buy for a couple thousand caps or you can make it using the ammo press and power cells, having every light on means the reactor uses fuel quicker but if you just have light on for the main area and the armory one isotope last a month and a few snow globes you can have the reactor fueled for quite a long time.
Vault-Tech Mobile Home this adds a man holes near a couple of Powder Ganger camps just a bit west of Good Springs, inside is a Vault-Tech Facility which after searching, hacking, and blowing up robots gets you a trailer, inside it has all you need plus the computer allows you to change the internal design and move the trailer to any key place which means from the beginning you can zoom right off to places like Nellis Air force Base and in doesn't take time so in hardcore you Sleep, Food and Water needs wont increase.
the facility also have truck loads of rations which if you play hardcore means you don't have to worry about food
both mods have the basics, beds, containers where you can store your stuff, toilets to drink from, and both mods put the home in the map for fast travel. i use the Underground Hideout as my main base only in Good psrings and use the Mobile Home to jump only to places i can fast travel to cut down on travel time to others nearby
