First time buyer

Hello

I'm just looking for advice/ people's opinion as to if i could get a mortgage

I'm 21 and i am a first time buyer

Ive seen a house i really like priced at offers around £65,000 (what would be a reasonable price to offer first)

I have a £21,000 deposit which i've worked and saved very hard for, i could maybe stretch to £21,500

I earn £854 a month, this may soon be increasing by £100 if i can get more hours at work but could be nearer to the end of the year

I have no debt/ loans/ store cards etc...

Thanks for any help :)
