Hi Nehal,
At 15 you may well be precluded BY LAW from signing a legally binding contract, but if that’s not the case you could look at becoming the ‘purchaser’ in a rap deal, provided the property was right.You could perhaps find one or two “flatmates” to help with the repayments, then in a couple of years when some equity has been amassed you wouldn’t need a ‘deposit’ and you would have established your bona fides with mortgage brokers to buy the property outright.
But a job kinda helps!
Good luck, and keep thinking about it.
RC for,
