As others have pointed out already, the items I noticed from looking at the listing, the pics, very briefly looking at the market, etc:
1. The front elevation is a bit stark in terms of color and curb appeal.
2. The interior photos are amateur-ish: Over-exposed (especially windows), viewing angle set too wide for the camera lens (some curvature on lines that are supposed to be straight).
3. No staging; this is a really big mistake, not just in this market, but any other. Buyers have to be able to see themselves in the home with their families. This requires proper staging to provide ideas, perspective and scale.
4. No floor plans.
5. This is 2019! Why is there no 360/3D tour to REALLY show the space.
As others have mentioned, when all else is right and the house still does not sell, or draw at least an average number of showings, it's about the buyer's perception of value vs. price.
Why did you price it where you did when you launched the listing? Revisit the steps with your agent and make sure you agree with her rationale and logic.
What does the competition look like? Have you, yourself, visited these competing listings with your agent in tow so you can compare and contrast similarities, features and benefits and then reflect in your marketing.
Do you know which demographic you are targeting? Millennials, move-up buyers, 50+, who? Then target your marketing to that group.
What is the market doing in Magnolia; how many active, under contract/pending, sold, withdrawns, etc. Is your situation better or worse than the market?
Has your agent conducted any OPEN HOUSES? If yes, what is the feedback from those folks who walked through the property?
Has your agent conducted a Broker Open House? Just like everyone on this post, we all have opinions. If your agent invites Brokers with a some wine and cheese tray from your local HEB store, you will get a bunch of feedback, which could be used to sell your newest flip!
Best of luck to you! I wish you well.
