Please help me on this comp situation

[Steven McPherson]

I've got a target property that is about 1900 square feet and sits on 2 acres of land.  It's not located in a rural area.  When I run comps, I get a ton of recently sold homes but they all sit on no more than .24 acres of land; so the house size is similar but the lot size is completely different.  How exactly do I evaluate this?  Does the size of the lot make the property more valuable?
