I used my first months paycheck on a self built PC, then saved almost everything besides rent for living at my moms for the first year to be able to have over $7k in my bank account to go to auction with
, chased about 12 Lots, and won the very last one, that I liked the most, but it cost about £6k more than it needed to
the result is my investments not starting until I was already 26. 
@obrienciaran not sure how people go about it internationally, but
in the UK John Butters Bee is the largest provider of home auctions. I delayed moving in for about a year because I had to take it back to brick and redo all the wiring, plumbing, plastering, floors, RSJ from removing walls
et cetera.

as a fun aside, their auctions are often on “homes under the hammer” so if you win a Lot while they are recording, you can approach them about being on their program
I almost did, but they kept delaying the interview session for the shows opening and by then I had already cleared out the previous owners furniture (auction lots come with EVERYTHING left inside after the viewings conclude, so I got 20 year old furniture I had to clear out somehow
) and begun taking down the crumbling plaster. the pay is just £150 for the appearance, but it helps with some of the finishing costs of your refurb
