Was very conservative on applicant selection. 

I dont agree with this thought process never have never will.. its all situational.. or as they say in RE location location location.in markets with slow to historic negligible appreciation sure it does not take a rocket scientist to run the math that if your negative cash flow and the house is not going up its not the greatest investment your value play there is tenant is paying off the majority of the property and your getting some tax bene's if its not bare land.If we used this thought process IE the only good deals are ones that are positive cash flow day one with max leverage  80% loans then as @Russell Brazil states no one would invest in the majority of the east cost and West coast and well Denver and other select cities.. everyone would be in the Rust belt and mid west or deep south in C class properties. wealth is created for most investors with appreciation full stop.. because most investors cant buy enough property or doors to make a difference when cash flow is 200.00 a month your not going to retire on that. your going to retire on paid for nicely appreciated property.

You're totally right about Denver's appreciation—it's been impressive, but it's also driven up property values, making it tough to find good rental yields, especially with a $600k budget.

ROE is not that impressive with around 3.6-3.8%. 

Depending on your area you might find a nice selection on Turno that you can rotate through. 

When looking for a PM, consider these criteria: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 (caution: 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.

These tools include the strategic use of domestic charging order protection (COP) entities in select jurisdictions as well as the revolutionary Bridge Trust ®.

I just purchased and closed my first deal on Paperstac on thought I’d share some pros and cons.Pros-  Great selection of notes which made shopping for what I wanted easy.

Very impressive getting a property under contract already.

I've been checking out CI and haven't been impressed.
