Hidden Costs

[Kyle Spearin]

What are some of the hidden costs associated with buying and flipping houses?

[Ned Carey]

As said Holding costs,  but also purchase and selling costs. 

• Heating in winter and cooling in summer - your contractor will have the utilities cranked up full blast because they have the window open so paint and drywall mud will dry. 
• Insurance - builders risk two to four times as expensive as regular insurance.
• taxes while holding the property
• Transfer taxes to buy and resell
• 2 sets of closing cost
• Real estate agent commission to sell.
• Financing costs - more expensive due to risk of rehabbing. Remember after you are finished the rehab you have another 30 days to sell and then 30 days to close before you see a check. That extra 60 days has to be financed too!

I'll add to @Walter Keys list of forgotten items - doorknobs. A whole house full of little items like switch plates, door bumpers, and doorknobs can sure add up.
