For me I would not buy a property with zero or negative numbers. 

Does anyone have any positive or negative experiences?

Not sure how many PMCs you've had bad experiences with, but we'll take exception to:"Then do a thorough research on tenant applicants (note: leaving this to a PM may be hazardous to your financial health)".BP seems to have more threads about screening mistakes by DIY landlords as opposed to PMCs.Now, if you'd have mentioned Maintenance, you'd get no argument from me:) Even the PMC industry acknowledges maintenance as one of the biggest challenges.Rereading my post, I kinda see how I sounded negative toward PMs.  

Unless you want to continue having negative cashflow, you pretty much have to raise rents.

Negative cashflow adds risk. 

if you buy a random property in a neighborhood you've never been to and turn it over to people you don't know you'll just lose money.not trying to be negative, trying to protect you and your hard earned cash.

I invite you to perform the exercise and find what your cap ex allocation should be.certainly $50/month for maintenance/cap ex and misc is not enough and this property is definitely cash negative when properly allocating for expenses.  

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.

Today poor means negative cash flow.  

When I checked their reviews, I first started with the negatives ones and they were similar to the ones found on Reddit.
