What are Considered Fixed Expenses?

[Riley Smith]

Hey guys, I have been practicing analyzing deals to fix and flip. In the book How to Invest in Real Estate it gives the formula 

ARV - Rehab - Fixed Costs - Desired Profit = MPP. When flipping what would be considered Fixed Costs? How would I estimate fixed costs? Thanks, everyone! I appreciate the help!

the best way to estimate is using actual numbers.  actual utility costs, security costs, insurance costs, for however long it's going to take.  3 months or 6 months or 12 months or whatever.
