A good post but I think you are light on the rental , if you want more than a shoe box it’s going to cost more than $ 4,000 per month in some cases considerably more .
Utilities $ 290pm , possible only if you are very careful but in the summer heat running 3 a/c units expect to pay significantly more
so that doesn’t leave much for your retirement or fun to be had with the family . Basically you will be working to live
