The solar on it's own may be a R400K investment, but will easily recoup R600K because I paid trade prices and not retail. If I spend wisely on the upgrades for the home then I should bank what I spent plus maybe another 25%. We bought the property at such a good price knowing we had to do so much and maybe have a good $100K to spend without over spending. We should get some advice from the agents in the area first. The plus side is this cost of the upgrades will be financed form cash deals I do with the business so it is kind of hiding those.
