My recent post on appraisals generated some thoughtful and insightful comments. One noted some folks may not really know what a “good comp” is. That got me thinking.

Sometimes we “more experienced” investors forget that people new to the real estate investing world are hearing many of the terms that we widely use for the first time. “Comp” is definitely one example.

So let’s start at the beginning.

  2. It will be a similar property. If you are trying to determine the value of a three bedroom two bath home you do not want to look at commercial properties. Rather, you want to find other three bedroom, two bath homes.

  4. The comp should have other similar features if possible. These could include items like a two car garage, a similar sized lot, fireplaces, central heat and air, etc.
  5. The comps should be similar in age and condition. …read more
