Splitting 2 Lots Shown Under Same Address on Deed

[Mike Jernigan]

I have a property I might want to separate into 2 lots depending on the potential return.  The property address shows two lots on the deed.  Does anyone have experience doing this in Bexar county, 78211 zip code?  If so what might be the approximate cost and timeline?  What would be the procedure I'd need to follow?

And I'm open to any tips or advice, thanks.
