There are many variables with interior real estate lighting to consider. Things like reflections, shadows and perspective control. Many use extreme wide angles which imo, is deceptive when representing square footage. Some use HDR to get the most in apparent exposure , which also can be distracting with over saturated colors and way too sharp details. The use of soft boxes, grids and umbrellas should work nicely to diffuse the light to keep the shadows at a minimum. Thoughtfully placed strobes behind furniture or doors and walls can create dimension and character. You can even place a light with a warming gel outside a window to simulate a warm sunny day with dapples of light on the interior. Placing the lighting on either side of a room should mitigate strong shadows, but diffusing the light is key, imo. The use of a tilt/ shift lens could also be used in tandem by simply "shifting the lens" for a series of images in either a portrait or landscape orientation and stitching together with an app. Or try just panning using several images and stitch in post. Continuous lighting is also an option for interiors, but imo, strobes have more power to control ambient light outdoors. Clean, higher ISO also can get you good images too, with a minimal amount of lighting.
