We read the Biden administration's proposal to protect renters from discrimination and unwarranted rent hikes. Here are the 3 biggest takeaways.

• The Biden administration announced several new protections for renters on January 25.
• New initiatives include investigating cases of discrimination and investing in affordable rentals.
• Some home builders say private industry, not government, should work on housing-shortage solutions.

The Biden White House moved on Wednesday to bolster fair-housing protections and affordability for more than 44 million renter households, or roughly one-third of the US population.
