Buy and Hold Properties

[Account Closed]

I know most investors are looking to get in and out of a flip in under 6 months (close to close) and others like rentals but what makes a buy and hold property worth it to you? Are there certain properties or lots that you'll pick up and just hold onto while the area appreciates? If so, what are the factors that make it worth it? With Philly appreciating as a whole 11% last year, with some areas carrying that number, it seems like a safe way to hold some money. 

Let me know your thoughts!
