Investors & landlords

purchasing and selling on different days would be treated as separate purchases and sales of the lots. to further complicate things buying at multiple times during the same day would likely be at different prices. thus with the sale of those shares there could be a gain on one of the purchases and a loss on the other. it can get very complicated. the loss would trigger the wash sale rules when replacement shares were purchased with 30 days of the sale at a loss. with wash sales the loss is added to the cost of the replacement shares. in the end since all the shares were disposed of the total loss should be the difference between the actual costs and sales prices.   the fact that there were no additional purchases within 30 days of the last sale at a loss would result in recognition of all the losses
