There will be just one source of income. This will be about $14,000 per month from an investment fund. While one might suggest an apartment above the garage, that is not realistic as there will be a need to build the apartment, and then adding both an elevator, and a spiral staircase in a firewall. The garage likely covers most of he width of the property, so it might eat up the valauble outdoor space that will be on the ground level.
If I can’t make $14,000 work for me, then I shouldn’t be managing my money. I will be able to support myself, and provide for a single foster child since I have a 2B house. Also, I don’t have to worry about my investment func not paying the income, nor violating a lease. I don’t have to worry about my investment fund arguing with me about rights they feel they should have because their mother told them they were special. The investment fund provides for income. 75% goes into the Swiss about, and 25% goes into the Money Market for taxes. Plain and simple.
