Legal question for as a landlord in Nevada SFR
I have a large 5 bedroom, 3.5 bath house for rent in Nevada. I had someone call that is interested in it. I asked how many people it's for and what the income is. It's for 1 person with the proper amount of income from disability. The disability amount is more than most professionals make. I asked why this prospective tenant wants such a large house for 1 person, and the answer was something like I don't really have to tell you that. If I have the income and want a house that size, I don't need to say why. Is it legal for me to ask why 1 person wants such a large house? As the owner, I'm wondering how the house will be used. I want to follow the law, but want to know if legally I need to consider this type of renter.
