Texas Client Wants Cash out refinance non-owner occupied property

[Sergio Rios]

I’m new so forgive my ignorance. Client bought a house several years ago. Lived in it for a few years, mother got sick so he moved in with his mother to help her. The property in question has been paid off for years and vacant. No renters nothing. He just got married, mother is well life is great so he bought a new home two weeks ago. We discussed him renting out the old house. Cash out refinance. Market value is $100,000. Take $80,000 and buy another one in the same street. Questions: In Texas can you get 80% on a non-owner occupied property? Should he wait until he has a renter to do the refinance?
