Closing costs are a one-time but significant expense. New Hampshire averages $7K in closing costs (1.6% of purchase price) while South Dakota averages $2K (0.7%). Much of New Hampshire's higher costs come from its 1.5% transfer tax, which adds $6K to the median home purchase.

Both states offer down payment assistance for first-time buyers.
