I would require them to show proof of income to verify they can afford the increase, then make them sign a lease.

I don't know about Texas but in North Carolina about 75% of the time you can find the LLC's owner name and home address by doing the following:Go to your secretary of state website (state not national)Look up the corporation nameAt least 75% of the time the LLC owner will register with themselves as the registered agent and their home address as the mailing address.If this doesn't work you're probably looking at more trouble than it is worth.

After taking all of those deductions, it is unlikely that you will ultimately owe any taxes on the rental income.
