Hi guys, im hoping someone here can help me out with a question i have. I have a friend that wants to jointly invest in a solar water heater with his land lord (50-50) but he will only do this if the land lord allows him to rent the place for 3 years. I have studied some law and i know he can draw up a contract stating just that and if it is broken then the land lord is liable to pay back the investment my friend has made so far. My question is: The law in WA is that a rental contract can be reviewed every 6 months, so on this basis is the method i said above valid at all? And is there a way to do this as part of a rental contract? As a side question, has anyone installed a solar water heater, and what kind of savings are you getting from it? Thanks in advance :D
