At first, it seems that architecture would be easier to shoot than “moving” targets, like people. But often it can be harder because there is no “life” that captures the attention of the viewer. Architecture just sits there. And so you need to be much more conscious of angles and light. Light especially. The exterior of a large home if photographed on a cloudy day can easily appear in a photo like a haunted house from a movie, but come back on a glorious sunny afternoon, and the house will seems to glow with happiness!
Does the house face south or north? Does the sunlight shine on it best in the morning or the afternoon? Those are important considerations.
And then there are the angles — buildings have straight vertical and horizontal lines (if they are built well!), so your photos should convey that. I always spend time in shooting and post-processing making sure the verticals align well with the frame of the photos.
And interior lighting is critical. It needs to be balanced with window light but not seem too “flashy”.
And are the drapes hanging correctly? Is the bedspread straight? Is the clutter of normal living tidied up for the photos? Attention to detail is critical.
