Well, start off by asking <em>what</em><em> </em>audience you want to reach? If you want to have a target audience to children, you would want to use easy-to-understand wording and most likely little kid characters who they could relate to.
Put yourself in the position of someone you want to target. Younger people? Well, how did you feel when you were younger/how do you feel now?
Do you're readers know you? Often authors will have similarities in the characters they write about, for instance a person of color might use a character who is also of color and explain about racial injustices they have.
Put yourself in their place and see from their pov!

A walkthrough which involves inspecting the property and making sure everything has remained stated and is in order is done by the buyer who is interested in owning the property. A buyer can always demand for a walkthrough. The walk through gives the buyer time to inspect the property before closing.
Taxes can be used to increase the price of producing or selling something which discourages firms from engaging in that activity. If the government wants to encourage a particular activity, they could subsidize firms who engage in it.
For example there are extra taxes on cigarettes because the government sees them as harmful, these extra taxes increase the price of ciggarettes.
