Looking for a low income apartment for rent in Las Vegas

Hello! I have an aunt who is in desperate need of a place to call home... ASAP! Please if anyone knows of a low income apartment for rent in Las Vegas (that has immediate availability) or a senior living property (that has immediate availability) PLEASE inbox or comment below.. She is also up to rent a room in a home for $600-$700 monthly.. No drama, no drugs, no pets. Lost a job 3 weeks ago do to the sickness of vertigo but receives social security and has the drive to work, so searching for another. She has a vehicle, very clean and respectful. If renting a room, if would be with an older aged woman preferred. 

Thanks in advance!
