Implement documented repeatable processes to reduce errors and improve service levels.By being efficient, and cutting some of your costs you can hire better talent with the leftover cash. 

Unless you have time, desire and knowledge, hiring a property manager sounds like the right option.

If you just hire the cheapest or first PMC you speak with and it turns into a bad experience, please don’t assume ALL PMC’s are bad and start trashing PMC’s in general.

If you have no clue what you're doing, hire someone. 

@Sean Gallagher not a sales pitch, but this is what we provide for investors in Metro Detroit:)Understand that if you hire the latest & greatest PMC, many grow using poorly trained VA's. - Your portfolio will suffer:(You want a PMC that has great systems in place, including a great portal where you can keep tabs on eveything.You will also need to manage your PMC on a regular basis.

On the other hand, I feel one of the main advantages of passive investments (via syndication/crowdfunding) is that I can hire a manager who has years more experience than I can ever hope to obtain myself.

With that being said, in a worst case scenario, you can always hire a property management company to handle the day to day items if it comes to that. 

We never hired a manager because it simply would have taken too much out of our profits.

It's definitely making me a better investor because I'm able to do my books myself now instead of having to hire a bookkeeper.

If that's not an option, hire an attorney and evict her.
