Interest [Abstract]

Interest

12. Interest

Interest is capitalized to inventories while the related communities are being actively developed and until homes are completed. As our qualifying assets exceeded our outstanding debt during the years ended December 31, 2019, 2018, and 2017, we capitalized all interest costs incurred during these periods, except for interest incurred on our mortgage repurchase facilities.

Our interest costs are as follows (in thousands):

	Year ended December 31,
	2019		2018		2017
Interest capitalized beginning of period	$	53,842	$	41,762	$	28,935
Interest capitalized during period		74,377		60,772		45,725
Less: capitalized interest in cost of sales		(61,150)		(48,692)		(32,898)
Interest capitalized end of period	$	67,069	$	53,842	$	41,762
