I definitely feel I was lucky. I had an interest only mortgage (all i could afford after my marriage ended) but my plans to repay the capital were nebulous to say the least. I was overpaying when i could and I was getting the capital balance down, but it wasn't down far enough.
Then the bad luck. Just after taking out a loan for a new (to me) car, which was essential for my job, I discovered I had cancer ‐ fortunately, it was caught early, treated quickly (and I got the all clear last year) but I couldn't work/ earn for 3 months - so both the car loan and mortgage repayments were a real worry. I got back to work - and then covid happened!
Furlough was sufficient to keep ticking over, but I couldn't overpay the mortgage and I had to rob Peter to pay Paul for the car loan. (Not to mention the mental toll of living alone in lock down.)
Then the good luck. I was offered a secondment to work on a project during lock down - well paid and as many hours as I could take. Then, after lock down, another well paid job opportunity came up. I overpaid on the mortgage like mad, I took some money out of a pension pot and I did it!
I'm still working at 68, but it's in a job I really enjoy and the money is replenishing my pension pot. I definitely feel i was lucky - if my cancer hadn't been caught when it was, if those job opportunities hadn't come up ...
