Almost all homes have defects which buyers will want the sellers to correct prior to the closing. When you know those defects in advance you can get repair estimates from contractors and provide that information to the buyers. You may wish to have some of the items repaired prior to listing the property for sale. A defect disclosure which is accompanied by a cost to correct provided by a reputable contractor can defuse a problem before it occurs. The unknown possible cost always appears more threatening and risky than a known expense.
Full disclosure is always the best policy for all parties evolved in a real estate transaction.
Its to your advantage to obtain an objective inspection by a disinterested party of your property. An inadequate inspection provided by a friend or contractor can produce expensive problems for both you and your buyer.
