cash flow of $450

[Kelly Williams]

I am about to get a 3 bedrooms condo overseas. Condo costs around 75K no closing cost. Maintains around $100 per year which is very cheap.
Monthly cash flow $450 USD 

My question is that, this sort of investment worth it or not? Meaning buying in cash 75k and having cash flow of $450 per month (tenant pays all the bills).

I am fairly new in investing trying to invest and get cash flow. Plz guide me what should I take into consideration!

how easily can you resell it? And does someone have to have all cash to buy or is it financeable? Will taxes go up after purchase? Positive rent growth or appreciation possible?

Numbers seem viable if the above stuff checks out, but not such a blazing good deal you can't afford to miss out. Whats the upside, whats the downside and whats the exit?
