Dang, I am the king of long posts and that last one left me tired. I get most of what you are saying. I agree it takes more money and time to do the first year, seller or rental. I just believe that a renter should not have to pay more the first year. I also believe that the owner of the lights should pay for thier maintenance after the 4th install, as that is when bulbs start to go. I especially do not want to own beyond year 7 or 8, when sockets and wire start to go. Theoretically, renters should be making more than me in years 2-7 as they will really need to start using that money to buy new lights in year 7, 8 and 9.
