After Repair Value (ARV). You will need a Realtor for this unless you have a real sharp handle on the market. Net profit--this is the number that you want to take home Carrying costs--every day you own the house it costs you money--mortgage payments, taxes, insurance, utilities Cost to repair--this can be really hard to figure out. Do an item by item number.Don't forget permits and city inspections. I always add in an "oops" category for things I missed or forgot about (4 comments)
