I'm the VP of a roofing company in South Florida and work with a few good PM companies on a regular basis, a lot of bad ones too.There are good and bad PMs in each of those companies. 

Properties are sitting on market for a bit longer now that supply is slowly creeping back up. 50 days isn't too terrible compared to the greater PHX area. 

They can't assess all the subjective data like overall layout, view from the living room window, the dogs next door that bark all day, the width of doorways, size of individual rooms, quality of kitchen cabinets and appliances, etc.The best thing to do is study your market regularly.

Quote from @Michael Smythe: Besides MANY self-labeled "gurus" exaggerating their success, many of them just supply readily available info.If you're too busy to find the info and are willing to pay for it, no problem as you accept their time vs money solution.REGARDING S8 GURU ISSUES SPECIFICALLYMost of them don't share all the facts about how Section 8 actually works.They claim you can get HIGHER rent from S8 tenants vs private-paying tenants.Why would the government allow our tax dollars to be spent this way?

With the exception of some small markets in the Southeast, places like Cleveland are the only major metro areas where a regular investor can find cash-flowing assets with a mix of appreciation. 

I can't tell the future, I just will tell you markets behave when supply and demand are close(r) to be met.

And while yes, no one has the same pricing (combination of factors), I also continue to check on a regular basis our rankings and how we "present" on total costs per stay vs. our competitors.My gut says there is price creep and we might have a ways to go before the market really corrects.

For example:"See how [Client Name] cut their supply costs by 20% with our help!""
