Can you update your location info via your user name in the upper right > User Control Panel > Profile tab? That way, we don't need to ask in future posts/threads or do sleuthing to deduce it.
You said 50 miles/day. How much city vs. highway? Will you have the ability to charge at your work/destinations?
I'm not sure why you'd want to pay more for certified. There's already enough of a price premium buying a non-certified one from a Nissan dealer. And, it doesn't extend the battery capacity warranty.
What are "the number of issues I've heard about"? You're in TX, so your biggest problem will be battery degradation and thus reduction of range autonomy, See viewtopic.php?t=13192
re: 5 year/60K mile capacity warranty and viewtopic.php?f=30&t=9694
for a summary of degradation.
As for "protected resale value", LOL! Leaf resale value is frankly terrible. It's good for used car buyers though. See viewtopic.php?p=430825#p430825
for what I got.
Unfortunately, the CHAdeMO inlet will command a premium. Who are the CHAdeMO providers in your area? Do you know the costs? In the SF Bay Area, Blink and NRG eVgo are the main DC FC providers, both a ripoff, $0.59 cents/kWh for the former and http://www.nrgevgo.com/san-francisco-bay-area/
for the latter. That why I didn't want to bother paying for CHAdeMO on the used Leaf I bought. My former '13 Leaf SV had it, and I used the port only 16 times in 2 years, all at free CHAdeMO stations (not many left).
If you're willing to buy new, you may just want to pick up a '15 since it has the "lizard battery" or wait for a '16 SV or SL since it comes w/8 year/100K capacity warranty and 107 miles of EPA range. If hitting 8 bars = 30% loss, that means ~75 miles of range. A new '13 to '15 Leaf w/new battery at 100% charge achieves 84 miles on the EPA test.
