To create this logo, I have used 4 elements. House, Key, Question Mark and Shield. These 4 elements are linked in a way that the outcome convey the message that "This company stops scammers and protects home owners and renters"
...............................................

House shape: this represents the home aspect.

Key: this shape represents the ownership

Question mark: The question about the ownership.

Shield: Protection against the scammers.

I paid special attention to making the design as simple as possible because more simpler it gets, more memorable it will be. The creation of the question mark as a part of the key is the result of that. It is a very unique combination.
