Thank you very much Hive account@realestate4114u !

Yes, I agree, it's always important to display the Logo on correct mockups that showcase the nature and the core of the business itself.

For longevitiy yes, first what's most important is the company's goals and values, quality of sales of the buildings, customer support, then I think comes the Branding into play.

Just remember when you will do Branding, I'd advise you to go for a simple and minimal Logo, abstract ones work best, it shouldn't show literally what you do but just to represent you strongly and clearly who you are while sometimes you can put a little something that relates to Real Estate or whatever business you are in.

Simple works best for all sizes, it's durable, will last for years to come.
