@Damiana19 I would suggest that it's your photo gallery and your decor that need some work.
I wouldn't lead with the outside photo of the house. No offense, but there is nothing unique about it-- it's a generic looking ranch house. So lead with a photo that will draw people in.
I would retake the photos that distort the space and make it look larger than it is. No need to try to get the entire room in a photo, take normal, closer up shots of each room from a couple different angles.
As for the decor, nothing wrong with the furnishings, but it looks like an empty barren home you just put some furniture in, and a couple things on the wall. It doesn't look cozy and warm. It's hard looking. I see you have blinds, but some curtains, in addition, would warm up and soften the look of the spaces. Some colorful throw rugs that can be easily washed. More interesting things on the wall, art, tapestries, posters, whatever. Some potted palms, maybe.
