Prior to his success, Armando Montelongo was so broke he was living with his wife and child in the garage of his in-laws. He was born in San Antonio, Texas, but was forced to move to California because of his wifes and unborn sons health problems. His job couldn't pay the massive medical bills that put him into debt. These challenges didn't discourage Armando- it drove him to find a way to get out of his predicament. He went back to San Antonio, Texas. There he found out that there is money in the real estate business. He discovered that buying a house, refurbishing it a little, then selling it, makes money so he ventured into that. This process is now commonly called house flipping.

Armando Montelongo became so successful with flipping that he now owns a company named Montelongo Housebuyers. The company, at an average, buys and sells 25 houses a month. By making money out of flipping houses, Montelongo earned for himself the moniker "Flipping Machine." He and his wife Veronica host Flip This House where episode upon episode viewer are treated to a transformation of a house. The reality show is rated seventh in a scale of 10 and is fast becoming a favorite of viewers specifically those who wants to invest in real estate.

Armando Montelongo is also hosting a website where he teaches, among others, the secrets of house flipping. Montelongo is passionate about his success and has a burning desire to share his knowledge to those who are willing to learn. He is currently developing educational CDs where he insists that there is money in real estate, where every investor can earn a million dollars within one year.

Some viewers are insisting that there is too much Montelongo in "Flip this House", with Armando's brother and his wife joining the cast. They want to bring back Richard Davis, who was the original host, whom they said was more entertaining. Montelongo was smothered in one episode when they were caught doing construction without the proper permit. The Montelongo Family enjoys playing practical jokes on one another. All these, however, may just be plain envy because Montelongo has turned the real estate industry in frenzy with house flipping.
