Where invest in Pittsburgh (buy+hold) in the city or in suburbs?

[Amalia Auge]

Hello everyone! My name is Amalia, I currently live in Pittsburgh, but I lived in Switzerland and Belgium before, where I was actively investing in real estate (still are). New to BP and real estate investing in Pittsburgh but I am pretty interested in buying rentals. Just looking for any advice about the areas that can be interesting (not in terms of appreciation even if possible it would be great) but of return of investment thanks to the rental income .

What is better? Out of Pittsburgh par exemple in Carnegie, Brookline/Beechview, Westview, Bridgeville, Shaler, Glenshaw, Stowe township, Crafton, Ingram? 

Or in Pittsburgh like Laurenceville, Bloomfield? Swissvale?.. 

My goal is to find stable tenants. 

I look forward your input, ideas, suggestions, I'm all ears. 

Thank you. 

Amàlia
