Look at their marketing strategy.

Hey everyone,I am coming into this game a little later in life. Currently have a great job but want to start acquiring  2-4 unit complexes. My first thing is to start built relationships with realtors and property man...

Quote from @Chris Webb: Anyone looking to get into a syndication, I would advise you do research.

@Zack Whiting how are you looking to scale?

If you're looking for the all-in-one I'd go with a PM software (others have suggested some) and do what you can with it.Then, as you grow further, look at more sophisticated/expensive options.

I would suggest look for a property management company to manage the property for you and slowly increase the rent yearly before selling.

What are you looking return-wise? 

Verifying last 2-years of rental history and income/employment extremely important to find the “best of the worst”.Tenant Default: 20-30% probability of eviction or early lease termination.Section 8: Class D rents meet program requirements, often challenges to pass Section 8 inspection.Vacancies: 20%+, depending on market conditions and tenant screening.Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciation.Where did we get our FICO credit score information from?

I would think this model works best if the property is close to you.

Best of luck!
