Subject: Better way to build string

I'm trying to build a query string based on an array of properties. Is 
there a shorter/nicer way to do the following?

   def build_query_string(properties, prop_type)
     result = ""

     properties.each do |item|
       if prop_type == "tag"
         result += " #{item.name}=#{item.value}"
       else
         if result == ""
           result = "?"
         else
           result += "&"
         end
         result += "#{item.name}=#{item.value}"
       end
     end

     result
   end
