Lori,
First of all I would like to say that I am very sorry for the bad experience that you had when you purchased your home. I have never heard of a Realtor recommending that you didn't get an inspection. A FHA inspection (as you probably know) only covers a small list of things that they consider important and that is not all that could be wrong with a home.
There are several things I would look for in a Realtor. You really need to find an agent who is involved in your market. I would look for someone who has sold homes in your area and is a full time agent. You should expect someone who devotes all of their time to the profession and doesn't just list homes on the side. An agent with a record of sold homes in your area would have the experience to tell you what improvements to make in order to get the most money for your home. In our current market some improvements are necessary in order to compete with others and even be considered. There are many homes on the market and you control only 2 factors in the sale of your home, price and condition.
I would recommend getting an inspection before you list your home if you are worried about what might or might not be wrong. Very few of my sellers do this but for those that do it eliminates surprises later when the buyer brings in an inspector and comes back with a long list of repairs. An inspection would catch things that are not up to code or other improvements needed that are not obvious to you now.
You could always hire a stager (recommended by your Realtor) to see what you can do to improve the appearance of your home. A stager is a small investment in selling your greatest investment.
Finally, I would look for an agent who does more than just putting the home on the local MLS. I would not sell my home with an agent who is not a premium member of Realtor.com. In a world of Internet buyers it just makes sense to get the most exposure for your listing online. Realtor.com can handle up to 25 pictures and your local MLS probably only does up to 10. Exposure for your home is what you need and a good Realtor will provide that for your home.
When it comes to buying a new home always get an inspection! There are so many opportunities right now. Interest rates are down and home prices are great. Take advantage of our great market.
There is no better time to buy!
