Well obviously, you have a house but you need to provide much more to the scene in order for it to look more realistic, such as landscaping a better lawn and street surface. What stands out immediately is your window glass settings need to be tweaked. it looks like you have 100% reflections going on and you need to back those way down. Put in much more transparency and put a black box inside your house to prevent viewing through the walls when looking through the windows. Use some Fresnel effect.
You need to have an environment to reflect that is much more realistic. That can be taken care of fairly easily by applying an image to a poly to reflect.
You need to tweak your lighting and then tweak your surfaces, this is why surfacing is done in Layout to allow you to apply surfacing in the environmental lighting to get it looking right.
Once you are satisfied with the overall lighting and surfacing, you need to adjust your renders to get the look you want, try adding a bit of grain and reflection blurring and perhaps tweaking the gamma settings. Some artists like to put a bit of fog in the scene just to soften up the render a bit. but beware and don't over do it.
This is just a start, but it will get you closer to what you want , remember to look at your reference photo and see what needs to be done to get your scene to that point. Is it lighting? Is it textures? Is it simply how to get away from that CGI look? This is a process or work flow thing, to work toward the final render of what you imagine. Hope this helps
