What you need to know before you flip a house from CNBC.
More and more people are flipping houses — the most in 10 years – but they are reaping smaller rewards. High home prices, hot competition and very, very few available homes to buy are combining to make this popular trade ever more risky.

Just more than 207,000 homes were flipped in 2017, according to a new report from Attom Data Solutions, which defines a flip as a property bought and sold in the same 12-month period. That is the highest number of flips in a decade. The number of people or companies flipping homes, 138,410, also jumped to a decade high.
