Can I retire at 39 years old?

[Mark Rosario]

My situation is pretty simple.

I'm currently 39 years old. I'm single with no kids or girlfriend. I've been busting my butt over the past several years and now have my home paid off. I have 3 bedrooms rented out and collect $1700 a month. My total expenses including HOA, Prop taxes, Home insurance, Car insurance, Gas, food, eating out.. EVERYTHING come out to $1100/month. This leaves me with a cash surplus of $600 every month. I also have $50k saved up in the bank along with another $34k or so in an IRA. A lot of the people close to me say I should keep working to save even more money to build a better retirement but I'm a man that likes less. A perfect day for me is waking up, watching TV on the couch all day and going back to sleep? As far as health, I'm healthy enough and plan to seek health care in a country where it is cheap when the time comes or even getting citizenship in another country and getting health care completely free? Can I retire? It seems pretty straight forward but since I work so much, there's hardly any time to even think. Thanks in advance.
