It depends on your goal...if you're looking for positive cashflow, I'd recommend rental income properties in not the best neighborhoods, but with section 8 renters...sometimes you can still get 10% cap rates there, and you don't have to hunt down the rent.
If your goal is to have a safe investment with a lot of appreciation/re-sale value and decent rental income, I'd go with a 2-3 bedroom condo on the beach...there will always be high demand for ocean view from renters and buyers.
If you're looking to get a permanent visa to the US, there are new constructions where you can invest $500,000 + and have vested interest here.
I am a realtor, LCAM property manager, and used to be a mortgage broker...I can help you set up a customized search and guide you along the way, then, manage the property for you. Or, you can look around on our website...if you have questions, contact me directly: firstname.lastname@example.org
