In my case bought a flat from a developer when I was 22 on basis of first job. Didn't rent as it was cheaper to buy. Deposit of 5% paid for out of savings (which I know I was lucky to have when I was 22). Good price as devloper had sold out the development apart from our flat and therefore anything we paid was stright profit, Interest only mortgage, rather than repayment. Used money saved by not having repayment mortgage for investments.
Invested money wisely while living in flat, inherited a little, bought 3 bed victorian terrace in prime location 4 years later, borrowed quite a bit more from bank and small amount from parents. Again IO mortgage, again used money saved by not having repayment mortgage for investments. Sold up investments 1-6 months before lehman brothers collapsed (luck not judgement) in order to buy forever house.
8 years later increased deposit thanks to some inheritances and good investments, general nervousness about housing market meant all of a sudden prime property was not selling for ridiculous prices, bit bullett and took out new mortgage without selling old house. Bought 4/5 bed semi in prime location had 2 mortgages (1 on old house 1 on new house - to turn us into serious contenders as buyer for house) when banks would still just about lend to people with equity and steady jobs.
Sold victorian semi 9 months later not at top of market or anything near top of market but beginning to feel wary about level of debt. Reduced mortgage on house we now live in. Could possibly pay it off in full but still not sure its better than investing money in other vehicles than property - which I don't udnerstand as much as shares, bonds, and various other financial products. Some in bank as cushion against possible loss
Overall managed because husband is very shrewd with investments, good and leverage on savings/investments (we always make more with money than banks chareg in interest - high risk but high reward if it works). We earn a lot between us now, but even when we didn't always looked at savings, and how to make money and investments, had nerve to buy when no-one else wanted to, plus some luck with a little parental help and then some inheritance at good times.
