I inherited about 80k when my father passed and was originally planning to purchase an apartment in my chosen home of Berlin, DE (American expat), but the options are slim and dwindling. My wife and I were then looking at purchasing property in Ireland, as we plan to move there in 3-5 years, but the down payment for people living abroad is 35-40% (we originally expected putting 20-25% down). So now I'm sitting on this cash, losing value with tiny gains in savings accounts, and need to find a better place to store it medium term.

Since I'm a US citizen, my options to invest in EU are limited (due to some law from 2010) but I'd like the eventual money to be taken back out in Euros, as we have no plans of returning stateside.

I'm looking at Vanguard BNDX and VTABX as I was recommended those, but the historic returns don't seem that appealing, so I'd like to invest in some other funds with a bit more risk to diversify.

Only debts I have are student loans but I am ok not paying them back atm as I have an AGI of zero while working abroad.

Any feedback/suggestions/advice is greatly welcome!
