House for 6mn with a deposit (down-payment) of 1mn = Loan for 5mn
Assuming no principal payments in Year 1 means interest at 16% [HFCK] before other closing costs is 800,000 per year OR 66,666 per month.
Add the following: Land Rates/Rent, Maintenance, Security, etc which can easily add 3,333/month to the cost.
So the minimum cash outflow in Year 1 is 70,000. At a tax rate of 30% the 'owner' needs to make 100,000 per month just to pay the mortgage. What about other expenses???
