I knew some of the Peer Street management.  

I would consider getting out of property management and getting into cleaning IF you think they are doing better than you . 

Are you already working in property management?

Try interviewing at least three managers.1.

When evaluating a property management company, it's important to look beyond just the management fee and consider the full scope of services and costs involved.For example, at our company, we charge a 10% monthly management fee, a $250 lease renewal fee (unless it’s a takeover tenant, which requires additional effort to establish a strong relationship - because usually people are changing pm companies for a reason), and the first month’s rent as a leasing fee.

@Kieran Collings - I'm an investor, flipper, and own and run a local property management company.  

Quote from @Andres Lasaga: I am in the process of selling a property to the tenant I have been renting the house for 4 years.I want to outsource the promissory note collections and reportsIt would be only ONE property, for now, any recommendation of a company that can manage the collections and reporting?

New Jersey property management is pretty bad overall.

The ability to effectively self manage would depend on the scale you are trying to buy. 

My wife and I started managing more properties for others as word of mouth recommendations started and we started to use the management and arbitrage cash flow to acquire our own properties and fund the BRRRs we were working on.
