I also would agree that with the Holiday Weekend just passing and it's been pretty hot things tend to slow down a bit.
I understand that you just did all this work on the house, but it looks pretty drab from the pictures. Maybe a warmer neutral paint color would have helped on those walls. The pictures could use a little help, especially the one with the plants in front of the window, not sure if I was buying a house or plants.
Now lets talk price, you have to be very aggressive in this market especially if your looking to sell quickly. I have not pulled comps for this house but make sure your are priced to sell and if you do not see any action within the first 30 days you need to lower your price and continue to do so until it sells. Unfortunately sellers are taking more of a beating and not getting back what they have put into their homes.
Another scenario for you would be to have your agent do some creative marketing with her/his lender. Do something different then everyone else.
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.
