The properties you choose to view (in "an" order) makes a large impact to the like-ability of a home. Most buyers when working with realtors work off of their "budget" and other affordability issues. Some examples may be "less than $500,000, between $250,000 to $300,000 or no more than $80,000". Some buyers may choose to work on a large range, say between $400,000 to $600,000.
Even within the same price point (for example: $250,000), there are yet many different variations of homes in the same market say Frisco TX real estate as an example. Some could be "plain Jane" properties but because of location, that may seem like a steal at $250,000. Some newly available properties on the market may be overpriced at $250,000 while others compete the $250,000 with qualitiy and featured upgrades like granite countertops, stainless appliances and hardwood floors. Owner-occupied homes versus vacant homes versus professionally staged properties do make a huge difference in selling the properties too.
Thus, as realtors, the houses you pick for your buyers or as Buyers, the houses you pick to see will make the experience a positive excitement or somewhat negative after-taste in the home buying/ viewing process. Somehow the order in which you select the houses to visit does affected the likability of a house.
Loreena, the other thing that is very helpful for buyers is if the Realtor has the time is to preview a handful of them before going out. That way you can eliminate the obvious ones that just have too many problems.
