deposit to hold property

[Rex Sundberg]

Hello, I have a property coming up for lease in June and I have found a tenant who wants the property.  Properties in this area rent very fast.  My question is can I secure a deposit/holding fee from them 2 months out to hold the property for them.  I dont want to lose money if they back out at the last minute and then it takes me 2 weeks to secure another tenant.  Can I keep the deposit if they bail?  I am in Texas and it is a single family residence
