Regardless if your showing a client property to a prospective buyer, or the owner wants to have the property appraised in connection for a sale, the curb appeal and condition can be important factors, which may affect the value.
Encourage the seller to tidy and spruce things up. Paint, elbow grease, and landscape maintenance can all improve the appearance of a property.
Eliminate foul odors, clutter or other elements which may affect a buyer or appraiser's opinion about the condition of the property.
First impressions can be lasting. When someone drives up to the property, does it look well maintained and inviting. Pay attention to possible perceptions, as this may affect a buyer or appraiser, or both.
Remember, make things as turn key as possible.
