Build a house suitable enough for your first town NPC, such as the guide, to move into.
A valid house needs: walls (background walls too), a door, a table, a chair and a torch, at least 6x10-ish in size. Build that near spawn and the Guide moves in - the housing menu's query tool tells you if a room qualifies. This is the template you'll repeat dozens of times for Real Estate Agent.
