If you were in a situation where you were sole "owner" (i.e. paying a mortgage - not paid off) of a small 3-bed terrace in a town which you bought when you were aged mid/late-20s and you've now climbed up to affording a larger house (semi-detached/detached) and/or in larger cities, how did you manage it and how old were you when you managed to climb up from your starter home?
Ideally looking for stories where someone didn't win the lottery or get a hefty inheritance to facilitate the step up lol.
Thanks
