$3,500 for a flat fee attorney for a multi-family deal: Fair?

[Kusum Chanrai]

Hello! I'm in the process of signing a contract for a multi-family in Houston. The property has 24 unit. I've been given 2 quotes from solid lawyers. 

1) $3,500 flat-fee: Includes review of PSA, title and survey work, final closing etc 

2) $250 per hour: The lawyer anticipates about $2,500 for the initial contract. 

Question: What are the range of attorney costs one can expect for closing a multi-family deal?
