Apparently, Microsoft started looking into the region's housing situation right after Seattle compromised on a tax proposal meant to raise funds for affordable housing and homeless residents. If you'll recall, the city wanted to tax big companies $500 per employee per year, but it had to settle for half that amount after pushback from Amazon. Based on what its consultant found out, the region has "counterintuitively done less to build middle-income housing than low-income housing, especially in the suburbs." That's why the tech giant is splitting its pledge into three.

Microsoft is lending $225 million to developers to subsidize the preservation and construction of middle-income housing meant for households making between $62,000 and $124,000 per year. The offer will initially be available in Redmond and nearby cities Bellevue, Kirkland, Issaquah, Renton and Sammamish. Meanwhile, it's earmarking $250 million for low-income housing development across the King County region meant for households making $48,150 for two persons. Microsoft expects to make very little profit from the loans, and anything it earns will be reinvested back into the project. The remaining $25 million will be given as philanthropic grants to organizations working to address homelessness in the area.

Microsoft President Brad Smith and CFO Amy Hood wrote in a blog post:

"If we're going to make progress, we'll all need to work together as a community. We recognize that Microsoft is in a unique position to put the size of its balance sheet behind this effort... Ultimately, a healthy business needs to be part of a healthy community. And a healthy community must have housing that is within the economic reach of every part of the community, including the many dedicated people that provide the vital services on which we all rely."

The company knows it can't just throw money at the problem to make it go away, though -- it's not even entirely sure how much $500 million can help. In an effort to make a bigger impact, Microsoft also plans to encourage policy changes for the development of affordable housing in state legislative sessions.
