We're mid-30s. We have a mortgage on our house (which I own) and my husband's old flat which is now rented out (mortgage is more than covered by the rent). They are both manageable (the one on the house is now about 2.5 times my income) but we would prefer to sell the flat if we could (we try for a short while each time it is between tenants). We could pay my mortgage down but as it is on such a low rate and we might move in a year or two
We live moderately frugal lifestyles compared to many of our London peers - no Sky, no designer clothes, very few expensive nights out, good use of leftovers. But we have our indulgences - waitrose for fresh food (much better quality than other supermarkets, imho, and we would rather sacrifice a few meals out to eat nice quality food at home), good loo roll (another fan of Andrex aloe vera here!) and infrequent but lovely holidays.
We are lucky and are very aware of that but we have also worked hard and made some sacrifices along the way. For example, when I got booted from my job a few years ago, if I hadn't saved through my 20s when many of my peers were out on the p1ss every night, I probably would not have been able to pay my mortgage, lost my flat and would have had to start all over again. And in an average year I probably work around 1/3 of weekends and evenings, which is pretty tough, as well as travelling a lot and spending time away from home which is only going to get tougher when we have kids but as I am the higher earner it will probably have to continue.
