lots of effort and some luck frankly - check leasehunter.com daily - some really fine leases show up there.
Talk to other hunters you know - I have people tell me all of the time to let them know if I hear of an opening - I keep their contact info and let them know when something comes up I hear of. Persistence is the key - If and when you find a good place then take care of it and keep it long term. No matter what anyone says or tells you, finding a GOOD lease in Texas takes some effort - if you find one it is gold
You can't fix stupid
