I don’t like being “beholden” to anyone, but my parents offered, and I accepted, the car loan of £1000. We saw it as a cash flow management issue. I needed a reliable car, they needed their car, I had been working for a year and saving like a demon, so they knew I would be good for the money.
There followed a decade during which time I had no debt at all. Then, at age 34, I bought a house. By this time, I had saved about 70% of the cost of the house, so I took out a small mortgage and paid it off completely in 18 months. Again, I was using debt as a cash flow management tool to buy something I needed and wanted, which was modest compared to my borrowing potential.
After the house mortgage was paid off, I had another debt free period, this time for 15 years. My NW was now in 7 figures. By this time I had had some business education. I was in a career path with no pension in sight and wanted to diversify my future sources of income. I was concerned about the market, and decided to begin investing in income producing real estate. I borrowed modest amounts, never more than 5% of my NW. I now own several income producing properties and own ~75% equity in them overall. Some I own free and clear. I have a slightly positive cash flow and in a few years will have a steady income from them when the remaining mortgages have been paid using OPM (other people’s money). The ROI on them is higher with some leverage, so I am not throwing money at these mortgages. During the crash of 2008-2009, my real estate income continued uninterrupted and was very reassuring.
OTOH, I keep only two credit cards, and one is for emergency use. I pay them off completely every month.
My attitude to debt is that it is a helpful wealth building tool when used judiciously, and always with the intent to pay it off completely. Taking on debt to buy consumables or experiences is not wise. Using debt to buy a right-sized home that meets your need for shelter and comfort, and which will appreciate at least at the rate of inflation, makes sense, provided you can ensure you will not default on the debt. Using debt to buy an asset that will produce a reliable income stream is good financial management in my opinion.
