The assumption is that i was paying all of it off at once
The car - at that time - was paid off (and it was a cheapie). So, had no car debt at the time of purchase of property 1.
My initial study loan - at that time - was paid off. So, had no study debt at the time of purchase of property 1.
When I purchased property 1 (you are correct in assuming that it was a cheap flatlet, R500k at the time), I pumped almost all of my savings and investments into the deposit and the outcome was that the bond was repaid in less than 7 years. It was actually cheaper living there, paying the monthly bond installments, than renting elsewhere for similar size.
When I purchased property 2, I had no debt either and was making rental income from property 1. All other debt consequently followed (latest car & study debt, CC, etc).
Back then I had to count every cent I had and was earning less than half of what I earn today. I'm still counting the cents and budgeting carefully.
