you're renting your home
so these are the rules for a home with rental and personal use
your personal use of your home is approx 7 months (210 personal days) while the retail was approx 5 months (150 rental days)
assuming the rental was at fair rental value and if rented to family or friends it must be rented at fair rental value and used by them as their primary residence. if not these days count as personal use days.
since your personal days are more than 10% of the rental days was the number of rental days less than 15 days? if no then (if yes, the property is treated entirely as a personal residence. do not report rental income or expenses)
treat as a dwelling unit used as a home. prorate expenses between personal and rental use. that includes mortgage interest and taxes
the rental portion of interest and taxes is not limited to retail income. other expenses like depreciation are limited to any remaining net income from the rental
any day rented at less than fair market value is a personal day not a rental day (that would increase the 210 days and obviously decrease the 150so if you rented at less than fair rental value for those 5 months
