Your agent has much more than the average as far as marketing in providing 12 pics on FMLS and attaching a virtual tour as well as providing a showcase listing on Realtor.com. Unfortunately, the pictures are extraordinarily unappealing and are unlikely to entice many people. The pics of the bedrooms and bathrooms are particularly bad. And despite the fact you have new paint, etc. the house shows as dated -- particularly the kitchen. And you should consider hiring a stager for a consultation. I'm afraid you are running into the reality of this buyer's market. There are dozens of homes out there for each potential buyer. And they want everything now -- perfect house, perfect location, perfect price.
One thing you might want to consider regarding pricing -- major real estate portals (like realtor.com) force buyers to search by specific price ranges. By being slightly higher than $150k, you are missing potential buyers who input their search criteria looking for homes up to $150k. Likewise, if you price at $149,900 you'll miss all potential buyers who put $150k as their minimum. By pricing exactly at $150,000 you will appear in search results for buyers searching to $150k as well as those search from $150k. It will simply expose your listing to more potential buyers.
But I suggest you stage the house and get better photos regardless of price. The current ones are simply not appealing enough to get buyers to consider your property.
I'm sorry if this comes off harsh, but brutal honesty is needed in today's market.
