Luck
and buying whatever I could afford in London with a huge mortgage, small inherited deposit, low interest rates, a good friend as flatmate and a bank manager you could talk to.
I went in and said I wanted to buy, had deposit and no job, straight out of uni, but did have a flatmate lined up. He told me to get any job and he’d see what he could do, so I started temping.
it was small, semi basement 2 bed flat, and not in great condition, but central and with a garden & garage in zone 1, just south of the river. Couldn’t afford north!
sold that 4 years later for double what I’d paid. And with that bought a 3 bed terraced house in zone 3, with a tiny garden, again not great condition but liveable.
Over 8 years we did work, loft extension, new kitchen & took walls down, while building works and materials were reasonable. Sold up 8 years later for double what we’d paid. And moved further out of London to commutershires to a newish build detached with 5 beds. Which is now just worth £1m over a decade later.
But without that initial small inheritance and crazy London property prices we couldn’t have done it.
the really annoying thing was I already lived in zone 2, beautiful area, but fresh out of uni it was too boring. DF bought a 2 bed flat in zone 2 at the same time as I did in zone 1, and his tripled whereas mine doubled and when I was married with DC1 on the way I was then priced out of zone 2
