Essentially you jut asked for a budget compact car with the space of an SUV, look of a sedan and the speed of a Ferrari. It's a strange, basically impossible to find combo in the camera world. I get it, you don't realize how little your money will get you until you start looking around! Used I think is your best option, but you won't be able to go back too far before you are into camera that are just too old.
Nikon D3200 or Canon T3i would be the route I would go. Used. Get a 50mm lens to put on there for portraits, (it becomes a 75mm on those APS-C sensor bodies), then get an 18-55mm kit lens to use for buildings. the 50mm will look great in interviews, with nice shallow depth of field. The kit lens, though not great optically will get you a wide enough angle and will actually be 55mm, because it is a lens designed for APS-C sized sensors. I think in this price range you might want to go the canon route, their entry level 50mm F/1.8 is a lot cheaper. And I mean a lot, almost $100.
