Well, presumably you wouldn’t live in a slumhole like I do. Any new apartment in China is going to look like an Ikea display. My house has been used only by transient foreign teachers staying only a few months at a time, so nobody has ever bothered to fix it up since the days when concrete blocks were considered luxury items in China. That said, even my relatively backwoods university is building a new foreign teacher’s housing block with modern amenities (including insulation), most likely due to open the moment I leave.
You could buy a foreclosed house in Detroit for $1 and then have the rest of your cash just for daily living expenses.
I don’t think that counts as “living nicely”. It is Detroit. 
Yeah - can you imagine having to follow the Lions?
I’m earning under 1% on my savings right now. I’m with Charter One.
My mom has been living in Hot Springs, Arkansas for the last 10 years or so (she’s 76) with approximately that much in savings. But she also has SS (both hers and my dad’s, even though they divorced and he’s dead) and a bit of retirement benefit and actually saves money each month. She lives fairly frugally by nature, but is in no way deprived.
Hey! Being a fan means it doesn’t matter whether your team wins or loses.
For the OP, with that kind of money, you’re probably much better off staying in the United States. I’d not recommend a $1 Detroit house, though, because there would still be too many neighbors, and it’s cold, and you’d spend a lot of money on heat (especially in that a $1 house in Detroit won’t have that latest in HVAC technology or even insulation).
Why not consider a tiny, little town in the middle of nowhere, USA? Out west, or southwest. Cheap property (park a trailer and squat), free emergency medical care (in the sense that you won’t be turned away), and everyone speaks your language. Or if they don’t speak your language, they speak the language that they would speak in Mexico.
To live poorly (by US standards), Mexico’s not really that much cheaper than the USA. To live poorly (by Mexican standards), well, that’s probably outside of your definition of comfortable. Of course the closer you get to high concentrations of American/Canadian expats, the higher the price of property. The closer you get to Mexican middle class (by US standards), the closer you get to US-style prices.
I’ve lived in Mexico twice, for a year each, and will start doing so again later this year (work-related). It’s cheaper, but certainly not cheap. I’d not want to retire there with a measly $150 kilodollars. On the other hand, I do plan to eventually retire there – far from the expats – but it will be with a bigger bankroll (well, I hope), and it will be cheaper than equivilent accomodations in select areas of the USA, but it’s certainly not going to be inexpensive.
