DRE would provide the service, and no initial cost for renting but the rent, so that a 100k/day apt costs 700k for one week, for instance.
Runners choose from the get go their pay plan but it can be changed while renting. Once the money is paid bu runners, it goes to /dev/null, like the CR paid to crytons and such.
The payment should be based on 24hr gmt, not in-game time. I dont even thnik game time can be accounted into any areas of the game as it never was.
