@Deepak C. recommend you hire a PMC to do Placement Only service.

Are you going to self-manage or hire a management company?

I'd say, if this is your first eviction, then it can be worth hiring an attorney to make sure you do it exactly by the book and your lease, so there are no delays.Or, you can reason with mother and son about leaving early with some incentive to leave ASAP.P.S.

They need to hire a property lawyer and issue a notice to cure and threaten to foreclose. 

I would first encourage you to hire a retail leasing broker in your market. 

But you will still be able to cashflow in some sort of way if you hire the right team in place and know what exactly is going on with your property.

Being an agent has nothing to do with reps because you need active participation in your real estate portfolio.

If I didn't self manage I would hire her to manage my properties.

Given your circumstances and goals, hiring a property manager could be beneficial, especially since you won't be in the same city.

Is it worth hiring someone to take care of the appeal rather than doing it myself?
