Real Estate Professional Definition for dummies

[Azin Eftekhari]

Greetings,

Can someone explain what the underlined phrase below means in simpler English? :)

A qualified real estate professional is a taxpayer who owns at least one interest in rental real estate that:

• - Performs more than 50% of their personal services in real estate trades or businesses in which they materially participate, AND
• - Spends more than 750 hours of services during the tax year in real property trades or businesses in which the taxpayer materially participates.

Thank you,

Azin
