Additional report context:
dispositions we sell apartment communities and other assets that no longer meet our long-term strategy or when market conditions are favorable , and we redeploy the proceeds from those sales to acquire , develop and redevelop additional apartment communities and rebalance our portfolio across or within geographic regions . dispositions also allow us to realize a portion of the value created through our investments and provide additional liquidity . we are then able to redeploy the net proceeds from our dispositions in lieu of raising additional capital . in deciding to sell an apartment community , we consider current market conditions and generally solicit competing bids from unrelated parties for these individual assets , considering the sales price and other key terms of each proposal . we also consider portfolio dispositions when such a structure is useful to maximize proceeds and efficiency of execution . during the year ended december 31 , 2017 , we disposed of five multifamily properties totaling 1760 units and four land parcels totaling approximately 23 acres . development as another part of our growth strategy , we invest in a limited number of development projects . development activities may be conducted through wholly-owned affiliated companies or through joint ventures with unaffiliated parties . fixed price construction contracts are signed with unrelated parties to minimize construction risk . we typically manage the leasing portion of the project as units become available for lease . we may also engage in limited expansion development opportunities on existing communities in which we typically serve as the developer . while we seek opportunistic new development investments offering attractive long-term investment returns , we intend to maintain a total development commitment that we consider modest in relation to our total balance sheet and investment portfolio . during the year ended december 31 , 2017 , we incurred $ 170.1 million in development costs and completed 7 development projects. .
