Most real estate agents will require a pre-approval before showing homes - this is especially true at the higher end of the real estate market; sellers of luxury homes will only allow pre-screened (and verified) buyers to view their homes. This is meant to keep out "Looky Lous" and protect the seller’s privacy.

Market conditions are a major factor in how fast homes are sold. In hot markets with a lot of sales activity, buying a home may take a little longer than normal. That’s because several parties involved in the transaction get behind when business suddenly picks up. For example, a spike in home sales increases.

Listing brokers represent sellers and charge a fee to represent them and market the property. Marketing may include advertising expenses such as radio spots, print ads, television and internet ads. The property will also be placed in the local multiple listing service (MLS), where other agents in the area (and nationally) will be able to search and find the home for sale.
