Would this be dumb, I found a house and?

I get disability and it would cover the mortgage for this house I want. And I'd have some money leftover depending how high my interest rate would be. I don't have any credit (even though I paid my car off) so idk how that would affect me getting a loan and the price of the mortgage. It's in an area I'd like to live in. And I plan on living there for at least a few years, so I'd rather buy than rent. I might live there the rest of my life. I'm not worrying about meeting a guy and all that or a family. It'll happens when it does and he's not gonna control where I live unless I agree. But anyway, good idea or no?
