Deductions & credits

Thank you for your response it was very helpful. 

 

Regarding the rental services that can be performed by the owners or by their employees, independent contractors, or agents. My question is, if my wife and I both are working on one of the properties together, do the hours count separately or as one? Meaning, if my wife and I are at a property and both of us are working for 1 hour does it count as 2 hours?  Another example, if a worker is working on plumbing for 2 hours and I have to be there because my tenant is not at home and I stay to supervise the work and look after their belongings can I use both times, the plumbers and mine, which would equal to 4 hours?
