I find as much info as I can on internet searches.

I'm wondering if I'm missing anything: Mortgage (20% down, so no PMI) HOA Electricity Gas (None, as the new construction house has an electric stove—everything is electric) Water Bill Camera Security System Internet Lawn Care Regular MaintenanceQuestions: Will I need to pay for trash?

I got into detail of what they were looking for first.. then I qualified that they had the money and were ready to go ( like a good car salesmen does) then I picked 3 properties ( back before the internet ) One I knew they might like one that pretty sure they would not and one I knew fit all the criteria and they would buy. then I asked for the order point blank and wrote it up usually on the Hood of my car.. contract with NCR paper and off er went to escrow.
