$45k Saved at 25! Invest?

[Michael Cavitolo]

Hello All! Looking for some advice! 

My girlfriend and I are both 25 years old, we have a little over $45k saved up together, It’s been a dream of mine to invest into Real Estate. We want to get engaged and get married In 2 years then buy a house. If it was up to me, I’d really like to find a duplex or 4+ multi family unit and start our portfolio now..  But we’re not sure if we should start it now or wait till the big events happen first. I just don’t wanna keep pushing real estate off, I want to dive In already.. 

Also, is $45k even enough? Thanks y’all!
