23 years old is still young. I was about 26 before my future wife and I bought are first house, a terrace house which we still remember fondly, we'd saved for about 4 years and put down a deposit of 20% and really stretched usselves with the morgage, when rates were higher than now, so we spent the minimum on other things, no holidays, shared car and I did extra work at weekends (maybe you could do tutoring?? ) and some side hustles like car boots (I even did a paper round again!) plus overtime wherever possible. A few years later we were able to move up again to the semi we wanted, but by then we were 30s.
Youve got lots off time
