Can you buy a house in another state and stay in your old house?

[Bryan Tasumi]

Can you buy a house in another state and stay in your family's house for the time being (until after you qualify for a mortgage)? 

I am asking this because I do not have a job lined up in Texas (where I am planning to buy my first home) and do not know if I can qualify for a mortgage unless I find a job there. I need to move very soon. I am planning to do this to qualify for a mortgage. I do not pay rent at my current relative's house and can stay here for as long as I like while I keep working at my current job. Will I qualify for a conventional house loan this way? Will there be any restrictions or negatives doing this or is this not possible? 

Thank you.
