Thank you both : )
Matt -
For a foreigner it is very hard to choose an area, especially in a country that New York alone is bigger than my own country LOL
If for example I want to choose an area in my country, it will still be easier even if I'm not familiar with real estate and even if I didn't visit it all (I didn't see most of my country :) ), because I know the language, the people, the rules (!!), I read newspapers etc - I live here, and I understand trends a lot better
I can (and I will) read articles on real estate in the US, and what areas in the country are going to develop and so on, but do you really think that I can take smart decisions relying these articles? :)
Regarding my expectations from property management companies - I read on our sites that there are companies that do almost anything
They have "property manager, a handyman, real estate agent, etc.".
You need to come with description of what you are looking - let's say duplex and probably more details about the budget for the house, rehab and so on..
After giving those details, the companies search for assets, offer it to you, you do your calculations and actually negotiate through them
They will handle the tenants, the mortgage, lawyer, fix issues - But all things should go through me
The problem - knowing what is a reasonable price for them to manage my property and to trust them : )
