We need this logo to mainly establish trust, and make the landowner WANT to contact us to start negotiations.
Some elements that we might like to see incorporated are things that give of a welcoming / inviting / trustworthy vibe (eg hands, leaves etc). We also want to avoid things that give the impression of a rich / money hungry corporation (eg large building etc). But we do want some element of property / house / development in it.
Once logo is decided on, we will also need a letterhead, business card, and envelope design which includes logo, corporate colour, and some other simple info (Eg address) that we will provide. We will need all the original (.ai, .eps etc) files for future use.
Update: the kind of hands we would like to see are similar to the attached pictures. we want the hands to appear welcoming.
