Now that you're looking at your house, not your home, and you're on the search for a good real estate agent, take a good, long look at the piece of property you are hoping someone will buy.
Get out a piece of paper - no, get out several pieces of paper, one for each room, and one for each side of the house outside - and a pencil. Label the pieces of paper according to which room - or side - they represent.
Take the piece of paper labeled "living room" and go into that room. Start looking the room over for those problems that you have grown so accustomed to living with ("I'll get around to fixing that soon" - well, soon just got here). Start at the ceiling. Are there cracks, old water leak stains, etc.? Do the light fixtures need a thorough cleaning or perhaps replacing for an updated look? Gradually work your way down the walls, ending up at the floor. Look at every part of the room. Make a note of everything you find that isn't perfect. You may not be fixing all of them, but you want to know what you've got to work with cosmetically - that is, problems that can be seen with the naked eye, and that WILL be seen by a buyer who is looking for reasons to eliminate your house from their list that they are weeding down to the one they will purchase.
Repeat this process with every room.
Now, take your sheets of paper and go outside. Go out to the street and look at your house for curb appeal. Again, look for problems - limbs that need trimming, grass that needs some help, empty places that could benefit from some plantings. Look at the gutters and make sure they are secure - do they need painting? Look at the roof from ground level - anything obvious there? Does the house need painting in order to look its best? Anything loose on the outside? Look, again, for those problems that will help a buyer quickly eliminate your house.
Once you've completed this process, put these sheets into protective sleeves and put them into a 3-ring binder. This binder will be your "planning book" in which you keep the information you come up with on your own and the information provided by the various professionals you are engaging to help you with the process.
Now that you have a list of what you can see that a buyer can see, you need to engage an inspector to do a "pre-listing inspection". This will tell you what things may be wrong that you can't see with the naked eye - the hidden problems that can jump up and bite you in the middle of a contract, costing you money in negotiated repairs or souring the deal entirely.
Hiring an inspector before putting your house on the market gives you the opportunity to decide in advance what repairs you are willing to make, to get estimates for those that you have decided not to make so that you are in a stronger negotiating position, and prevents some unpleasant surprises during the contract period. Providing a new inspection as part of the Seller's Disclosure form used in your state also gives potential buyers confidence that you're not hiding anything, and if you can provide evidence (receipts, warranties, etc.) in notebook form of all repairs that you HAVE made in preparation for putting your house on the market, that, too, goes a long way towards increasing buyer confidence in your home. Top that with a Home Owner's Warranty, and you could potentially see offers thousands of dollars more just because of that buyer confidence.
You can find licensed inspectors in the phone book, check with your state licensing board for references, or, best, you can get a few names from your real estate agent who has no doubt worked personally with many different inspectors and should have a list for you. Your agent will also be able to advise you on disclosure laws in your state once you have all the information provided by the inspector, and can give you a list of repairmen, landscapers, etc.
