That proximity to Houston and San Antonio will bring a premium on per acre price for sure. $40-$50 easy IMO, because there are a whole lot of people in both of those metroplex (hell, Austin and CS as well) areas that would gladly pay for something that convenient. I'd guess $30k unless you have the unicorn landowner that either doesn't care and wants good people or just isn't up to speed on lease pricing close to major metro areas.
Only kinda red flag is the 5 bucks/8does. Assume the landowner has a survey done to come up with those numbers because even if it is a 1 buck county, if you have more than 5 people somebody is going to get the shaft every year.
We are a 1 buck county and have 10 on our lease that is a couple hundred acres bigger. We routinely shoot 8-10 bucks every year, usually a spike or two, and anywhere between 6-14 does (1 buck, 1 spike, 2 doe county).
