Jennifer Borrero

Georgia Organizing Director

Housing Story

Growing up as a first-generation American from Mexico and Colombia, I witnessed firsthand how housing instability impacted my family and community, from overcrowded living conditions to the constant stress of rising rents. As I navigated my own journey, I saw how the lack of affordable housing limited opportunities for so many, creating barriers to education, health, and stability. These experiences fueled my passion for advocating for equitable housing solutions and ensuring that safe, affordable homes are accessible to all.

Senior Campaigns Manager

Housing Story

I grew up in a small town in Vermont – so small that I attended a neighboring town’s high school because our town didn’t have one. When I visit my hometown today, so much of it is physically the same. The same homes, the same farms, the same general stores, but so many of the faces I used to see around town have changed. The majority of the people I grew up with don’t live there anymore. Like myself, nearly all my classmates moved away in search of broader economic opportunity because even after pursuing higher education, we couldn’t afford to live in the communities we grew up in. The housing shortage impacts small towns, big cities, and everywhere in between. Housing in all of our communities should be abundant and affordable. As Matthew Desmond wrote in Evicted, “Without safe and stable housing, everything else falls apart.”

Tia Stone

Senior Manager of Membership

Housing Story

As a child of an all Black family, I grew up watching my family struggle to make their way out of West Las Vegas, the segregated Black community, and purchase homes in affluentneighborhoods. I’ve seen firsthand the redlining still happening in today’s real estate process. Las Vegas is also the number 2 fastest growing city in the country as people flee their cities in the post-pandemic economy. Las Vegas has not met the increasing demand for housing, allowing new residents with high incomes, many of whom are cash buyers, to sweep up homes in the neighborhoods with the most resources. This has caused a massive increase in home and rent prices, making it harder for locals to afford housing. New reports show the average person now needs to work 2.5 full time jobs to afford the average rent in Las Vegas.

Rafa Sonnenfeld

Policy Director

Housing Story

In college, I learned my share of the rent for my room would be higher than the mortgage for my father’s home. It took me a year of checking listings every day to find an apartment in my price range: a moldy converted basement with an illegal kitchen that had dozens of interested renters: I called it home for six years, always worrying I’d have to leave my hometown. Despite being eligible for 10 years, my local housing authority couldn’t even add me to the rental assistance waitlist.
