Moving countries may be desirable but it comes with its own set of issues--that may become bigger as you get older. There are plenty of less expensive areas in the states although they may not have the climate and other features you prefer.
Rent tends to be pretty unreasonable across most of the US these days as far as I've seen. And most places have next to no tenants' rights.
I have a friend who left NYC for an apartment in Sioux Falls, SD and his landlord changed his lease terms and payment structure multiple times mid-lease, doesn't have individual utility metering and just bills everyone in the building what they want and even bills him for utilities that they don't provide.
Everyone in the building who challenged it was evicted on three days notice.
I wouldn't count on international landlords being appreciably better on average and now you're in a foreign country.
Sure, there are asshole landlords and renting always comes with its own tradeoffs. But there are a lot of places you can rent for much less than NYC if you don't need a local job.
