I realize that, you search your on comps. Just trying to understand what you are actually looking for?
There are 4 ways to get comps into your report (feel free to expand)
1. Start from scratch and manually input the comps.
2. Import the comps from a MLS text file (shown above).
3. Use Alamodes smartexchange.
4. Use a data base that suggests the comps and import them into the grid.
I use # 3. Search my comps in the MLS, use the export feature in my MLS (not all MLS have this feature....) Then I use Alamode to import the comps into the grid. If you are looking for something that TOTALLY fills in everything, it does not exist to the best of my knowledge. In my above example, 80% is filled out. Which is pretty good. You could do more, such as garages, patios, decks, etc., but in my experience, it causes more trouble than it is worth.
