Purchasing all cash question

[Matthew Aubert]

I am looking to purchase a property (sfh) with all cash. I could use a realtor but if I don't then the seller's realtor will receive entire commission which no big deal. Just as long as the agent doesn't try to bamboozle me since they're representing the seller. My big question is what am I liable for at closing like insurance, taxes and such? Do I pay taxes upfront for the year? 

Also what leverage do I have since I'm paying all cash. Can I offer a lower amount since there's no mortgage? I understand the closing can be much quicker. At closing (for Texas) do I receive the deed to the property that day?

Any advice would be beneficial. Thanks in advance.
