Trustworthy people are usually trusting. 

I went with PM #2 after receiving a recommendation from my trust worthy source.  

You'll also have a challenge finding trustworthy PMs in high crime areas---many of the successful landlords in that area that I've seen know the area well (may have even lived in the area at some point or still do), manage their own properties and do a lot of their own work as well.  

Finding a property management company that you can trust with your investment can be a weight off of your shoulders and provide "mailbox" money to you without you having to lift a finger (except for when you have to grab that money from the mailbox).The cost of property management services varies, but any great trustworthy property management company can outweigh the cost substantially by providing you with time-saving services that handle the day-to-day operations of owning a rental investment property.

At the end of the day, interview and find yourself a trustworthy local to build a relationship with.

Hi fellow REI Could anyone recommend a trustworthy property management co for a smaller multi-fam apt (10-20 units) in the Central Jersey area?

What I'm wondering is what questions should I ask them to make sure they're trustworthy and legit?

Does anyone have a trustworthy siding expert in the KCMO area they would recommend? 

In fact, as a digital marketing consultant, I've seen research that shows a couple of negative reviews makes all of the reviews more trustworthy because we all know that, "Pobody's Nerfect."

I have a trustworthy friend who is down to walk the path of real estate investment with me.
