The "we buy houses" signs have been around for as long as three decades, but like everything else, you only see things that are of direct importance to you. While anyone can buy and sell houses in the United States, most people just buy and sell the house they live in or wish to live in.
Buying houses without the expectation of living in them-as a business, really started to take off about 30 years ago when a number of seminar speakers joined the county selling training in buying and selling homes for profit. As with any business, if you search for we buy houses in California, you can expect the number of people who buy a house to be skilled professional, honest and others that are not so skilled and some-that you want to avoid.
The point is that some of these people may actually help you sell your home quickly, sometimes within a few days, and solve problems. Others, I have found, will not even answer the phone or call you back, if you call and leave a message. Strange as it may seem, I have found that this reluctance to follow up on a lead happens in a number of areas in sales.
If they answer the phone and actually arrive at the time and agreed for an appointment, I would want to know how long the person has been buying houses and how well they do it. One of the biggest advantages that the best of these guys and gals will bring to the table to help you is that they have been taught that there are a number of ways to sell a house, methods that have been used in commercial real estate for years but that are rarely used in residential real estate.
