You will need to find partners, you will need to travel to where you wish to invest, you will need to understand the ins and outs of the business by being actively involved and treating it like a business and not some super passive investment.If you don't want to do that work I suggest you just put that 200k into some sort of diversified mutual fund that can make you 10+% on your money without any of the work of real estate.At the end of the day this is just my advice and I'm only a stranger on the internet.
