Jordan - Sorry I was too lazy to read the other comments, but here is my input.
NNN deals -
Make sure there is atleast 10 yrs on the lease.
Make sure the company is not struggling
read the lease and make sure it is actually NNN. Sometimes they will advertise NNN when the landlord actually has a few responsibilities.
Location is not extremely important, but if the tenant was to go bankrupt, you want to have a good enough location to potentially find a new tenant.
Make sure the lease is corporate guaranteed. This way they will continue to pay you for the duration of the lease.
NNN deals are hot right now, if you want to see a quick list of deals in your area let me know and I will email it to you.
quick story/ funny example - I know an owner of a starbucks that was NNN corporate guarantee. Starbucks closed the location and continuted to pay the rent because of the corporate guarantee. They negotiated with the onwer to pay him a lump sum instead of paying per month for the next X amount of years. The owner then re-leased the building to another tenant and after spending 70k on tenant improvements, he's making almost double what he would have if starbucks would have stayed there!
He was obviously VERY fortunate
