I know big maybe but lets say two identical offers come in with letters and pictures of the family making an offer.

@Paul Henning Cost per sf is a notoriously bad predictor of value, unless comparing nearly identical properties like two condos in the same building. 

House 1 and house 2 are identical in size, bed/bath count/lot size, and area.

Purchase price: $410,000 Cash invested: $40,000 4 Bed 2 Bath Duplex (Side by Side identical units) househack.

About a week ago there was an identical thread.

Legitimate companies do use electronic lock boxes for convenient self-showing, but those systems often require you to register through a site and verify your identity before entering the property

.- They are as close to identical as possible in style, condition, age, location, beds, baths, living area, acreage, garage and basement specs, town vs private utilities, flood zones, etc.Finally, I'd like to be sure that the agent hasn't run automated comps. 

I don't want to give away my identity, but for an example, we named his company 'XXX Real Estate'.

Tie your identity to daily actions...the results will take care of themselves.  

Promoting it and your brand identity is more about how you put yourself out there.
