For real estate interiors, the most important feature is a wide-angle lens. In compact-camera terms, about 25mm equivalent or wider is desirable; some models go to around 22.5mm, which helps in small rooms.

That said, even 22–25mm often still isn’t wide enough for interior real estate shots. Many photographers solve this by stitching multiple images into a panorama, so manual controls can be very helpful for getting consistent exposures and cleaner stitched results.

At this budget, don’t expect a compact camera to match the very wide lenses commonly used by professional real estate photographers on larger-sensor systems. A $300 point-and-shoot is mostly about getting the widest lens you can, plus useful controls and panorama capability.

So the key things to prioritize are:

• widest available lens (25mm equivalent or wider)
• manual controls if possible
• panorama/stitching support
• tripod use for best results indoors

If compact size matters most, you may need to compromise on manual controls or maximum width. If image-making flexibility matters more, a slightly larger camera with wider coverage and manual settings may be the better fit.
