Legal issues on referral fees...

[Pat Bruton]

I run a furnished rental by the room that has five bedrooms which are rented at $60/night for an average of 4month stays. So $1800 per room. Business is competitive and highly based on referrals. I want to give up to a $1000 referral for anyone who refers someone to stay for 4+ months. Can anyone point me to resources about legal issues with this? Who can get the referral? Is there a $ limit? Anything Texas specific? Etc. Thanks BP, Patrick
