Material Participation Hours for Real Estate Professional Status

[Rose I.]

Hypothetical situation: If I am working towards material participation hours on a relatively small property in terms of total value but get there in terms of the technical hours and the test, and say later in the year I purchase multiple properties but am unable to generate material hours on those properties (ex. maybe even <10 hours), would I be able to aggregate all properties for the material participation test and thus qualify the properties bought later in the year for the benefits of bonus depreciation with a cost segregation (helping to offset my husband’s W-2 income)?
