Investors & landlords

Thanks for the replies.  I meet the othrr requirements for HOH, I am just not sure if they rental home I rent is a 'Qualifying household".  I am single, and I have 2 qualifying dependents (biological children in college and I pay for > half of their expenses).  I rent the home I own for approx 80% of the year, and stay at that home approx 20% of the year.  The rest of the year (80%) I live with my girlfriend.  My girlfriend owns her home and pays for >50% of the home expenses where we both live.  She does not claim HOH because she has no dependents.  So is my rental home I own not a "qualifying household"? 

As a side note, for 2024 I was considering paying >50% of the home expenses where we both reside (her home) to possibly give me HOH status for 2024.
