A few important things I would be looking for:1) the experience and credentials of the broker who supervises the company as well as the lead property manager2) the services they offer and how they line up with your needs and expectations3) the use of technology to make their job and yours easier 4) if they have a landlord-tenant attorney on retainer to help guide them on legal issues (not to mention the creation of lease agreement, landlord forms and notices, etc.)5) their process and policy for a) listing, b) application, c) tenant selection, d) routine inspections, e) maintenance services, f) property and tenancy update reports to you, g) lease enforcement policy, and f) move-out process.6) property owner reviews (you can't always rely on Google reviews, because they may not reflect actual quality of the company, but still) 7) beneficial programs for both owner and tenant 8) a property management agreement that would indicate they know what they're doing and have the experience to know what matters in a PMA.

Your tenant has already signed the new lease, which confirms his agreement to the new rent amount, sending that notice via certified mail can act as an extra layer of documentation that can be helpful in maintaining clear records. 

If the tenancy is a specified lease term under a written agreement, and the lease term has not yet expired, you cannot impose a rent increase during the term, unless the lease agreements provides that you may do so. 

Unless the lease agreement says otherwise, the landlord must give the tenant at least 3 days to move out.

Also, be sure to have the landlord and property management resources you will need to manage the property properly, including having an attorney on-call for guidance and counsel, forms, lease agreement, and education. 

Before signing a lease agreement, conducting a thorough screening process can help mitigate potential risks and ensure you're selecting reliable tenants.
