I'm planing on taking some serious time off to work on my side projects.
I'm open to any country in the world, I want to just work on my games. So with that in mind I'll need good internet access. From what I can see, this is very doable in Eastern Europe.
Eventually, I do plan on returning to the US, but I want to spend at least 6 months overseas.
Housing is probably the biggest living expense. I take advantage of Korea's interesting rental system called Cheonsae:
Basically, if you put down a huge deposit (like $90,000: 50% to 90% of the value of the property), you don't pay any monthly rent and get the entire deposit back when you move out. My place has a $50 monthly management fee, but that includes high-speed internet. (So I joke that I get free housing with my internet.)
Of course, there is an opportunity cost because that deposit could have generated interest, but I figure the break-even point is 12% APY. (It is possible to lower the deposit by increasing monthly rent.) So it's advantageous to take out a bank loan at 2-4% interest to pay for the deposit.
There is a small risk you won't be able to get your deposit back if the owner mismanages their finances. I believe the Korean government actually guarantees housing deposits up to $50,0000 or so. In Korea, the tenants actually do background checks on the landlords! The minimum deposit is usually $10,000, so landlords usually don't scrutinize tenants.
