Technical Notes

While we tried to be as accurate as possible, a number of technical factors may cause the numbers of listings shown here to differ from the actual totals reported by the MLSs. This data is intended to only to show how many residential listing Home ASAP has processed from each MLS.

It’s also important to note that some MLSs such as RealComp MLS were added mid-year. This would cause their totals to appear lower even though they may be in a large metro area.

Other MLSs such as Beaches MLS offer multiple feeds with some overlap in listings. For these, we showed the estimated total only.

Finally, it’s also important to note that several MLSs have merged in the past year. In some cases, one MLS may have absorbed another MLS’s listings. In other cases, a completely new feed may have been created. Either way, the number of listings will have been affected.
