That tool really sounds ideal...I think in most major markets now that are either saturated or balanced in terms of supply/demand now more than ever amenity rich properties are a must. 

Gotcha a in other words rents could soften or are softening based on supply demand issues.. thank you for clarifying that.

A good PM can also help you determine what types of properties are in demand, what neighborhoods to focus on, and maybe even cross-check any properties you find to see if they are good investments.

@William TseChoosing the right property involves market trends, rental demand, neighborhood quality, and future development.

We originally hoped to rent as a mid term rental in a smaller town with a hospital, but the market quickly became oversaturated for the small demand so we decided to shift to long term rentals on both sides.

There is an excess of people (demand) who want a limited amount (supply) of something in a specific area.

Ya remove the demand. 

Its a delicate balance of supply and demand in a market. 

@Jaime Felber If you're in a good location with a lot of demand and not a lot of supply, it's easier than if you're not in an area with so much demand.

Analyze Texas and Oklahoma markets for rental demand and ROI.
