@David LewisRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

It seems to me that they all whether paid of free, will all have the same exact amount of houses because all the transactions are all public and so they seem to compete with each other based on the quality of the data of the houses, how up to date it is, and the user experience in configuring the how the layout is.

Let me know what you think.As a matter of information, smoking/vaping is prohibited inside our rental units.

The mailers I receive for my properties are not of a high enough quality, to make me believe the sender understands what gets a recipient to even open or read the mailer, let alone respond. 

They must provide quality service, or their clients won't want to pay the price.

Colors, quality of paint, how much prep needed, holes patches etc. 

Those qualities can be the difference between closing a deal and walking away empty-handed.What about you?

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.

It's acceptable as an area though the flips I saw weren't great quality.  

DOM can be minimized by a number of different factors including the quality of marketing, rent price, availability to show.
