OBLIGATION TO REFUND.Except as provided by Section 92.107, the landlord shall refund a security deposit to the tenant on or before the 30th day after the date the tenant surrenders the premises.A requirement that a tenant give advance notice of surrender as a condition for refunding the security deposit is effective only if the requirement is underlined or is printed in conspicuous bold print in the lease.The tenant's claim to the security deposit takes priority over the claim of any creditor of the landlord, including a trustee in bankruptcy.Acts 1983, 68th Leg., p. 3639, ch. 576, Sec. 1, eff.

But right there at the top, in bold print their "commercial" warranty states:  "Commercial/Non-Residential" - Despite several emails - they could not resolve this apparent discrepancy.

Bold strategy.

*I'm not sure I've ever bolded a comment on here before - feels like I'm shouting :)   In no way is this OK by any stretch in my opinion.
