You can contribute more to your Roth each year, until you have enough to parther with someone else (or their Roth IRA) on buying a rental property.You can also get money into your roth by converting other retirement accounts such as 401k (paying the taxes on however much you convert each year sooner, rather than paying more later, after it has grown, when the IRS forces money out of your 401k via RMDs).

I guess the only concern id have with that is if they changed their mind and wanted to pull out sooner than I did and it caused problems.

He was a bit of a player, so I mention to him that if she was on it and they had a fight, he could not kick her out versus as being a guest and therefore he could sooner.

I got interested in real estate though a podcast from Listen Money Matters and now wonder why I didn't start sooner!! 

The sooner you think of it as a business asset first and vacation home second, the easier that first year of rentals will be. 

What do you think needs attention sooner rather than later?

The absolute sooner the better because money talks.

Really enjoyed this podcast (made me run 20 more mins at the gym to finish the whole thing!)

@Joe PrillamanMy advice to myself would be to house hack sooner.

The more I think about it, I keep kicking myself for not doing multi-family sooner.
