Investing in real estate at 22

[Mohima Khanom]

Hi everyone, 

I am currently 22 years old and I'm looking to invest in real estate. I was just wondering if this is a safe first investment to make? 

I will be starting my new job later this year, however I will be on a trainee salary for the first 2 years which is around £35k. I intend to live with my parents during the first 2 years of my job, so I don't think I will incur a large amount of living costs. Therefore, is it possible for me to begin investing at 23? If so, what is the minimum amount I will need to save?  

Also, I am currently living in the UK and was wondering where it would be best to make an investment i.e. should I invest in the UK or would the US be a much safer market offering high returns? Should I invest in REITs first or look to purchase a property by getting a mortgage and then renting it? 

Thank you for your help and hope everyone stays safe!
