While technology has been changing the way we buy our clothes, do our banking, order a taxi and just about everything else, until recently little had changed in the world of home buying. Just a couple of years ago, a millennial’s recent purchase of their first home would have worked remarkably similar to their boomer parent’s home purchase 30 years ago.

Now change is coming, as entrepreneurs increasingly recognize the opportunities to profitably and creatively apply technology to the tradition-bound home buying process. Investors, too, are taking note; this past September saw an unprecedented $2.7 billion invested in real estate technology.

Why this boom? Millennials, more comfortable with technology than preceding generations, are now the largest group of home buyers. On the supply side, more and more software programs and apps are available to simplify the often-daunting process for would-be home buyers. The once tedious task of leafing through listings in the Sunday newspaper or at a Realtor’s office is being superseded by software that acquaints prospective buyers with communities that meet their needs, focuses on homes of personal interest, schedules visits and, in certain cases, can even make offers.

While technology is changing every aspect of the home buying process, three areas generating significant excitement are home search, online transactions, and the elusive opportunity for fast closing.

Online search tools are empowering today’s buyers by allowing them to target communities by what’s most important to them, whether walkability, school quality, safety or proximity to houses of worship. Buyers can also learn about price trends, new construction, and housing turnover, as well as a specific home’s ownership history.

Going further, some apps and websites are even allowing buyers, in cooperation with a real estate agent, to make offers and to apply for mortgages. This provides the would-be buyer with an upfront understanding of their mortgage eligibility, the associated closing costs and monthly costs, and access to the best possible terms and conditions.

Technology start-ups are even tackling the last big challenge: the significant time lag between going to contract and “closing,” taking ownership of a home. While there are still legal and regulatory hurdles to overcome, it may be only a matter of time before closing on a new home will be as simple as ordering groceries online.
