Low income apartments?

I live in low income apartments and they have been just put under new ownership... if the new owners were to make the apartment now no longer low income then what happens with the tenants? I have lived here for many years.. they aren't section 8.. at least i don't think so .. i think they are HUD.. but anyways im just curious.. can they just kick us out or do they have to relocate us or maybe even give us section 8 or something... it just seems weird that they could just kick us out... and like with my monthly income i don't know how i would survive... and also, some people were on a waiting list for 4 years just to get in here... please only answers from people who have experience with this.. thank you...
