maybe not all all deductible - you say this is a vacation rental, did you vacation there in 2018.
If you rent a dwelling unit to others that you also use as a residence, limitations may apply to the rental expenses you can deduct. You're considered to use a dwelling unit as a residence if you use it for personal purposes during the tax year for more than the greater of:
14 days, or
10% of the total days you rent it to others at a fair rental price.
There's a special rule if you use a dwelling unit as a residence and rent it for fewer than 15 days. In this case, don't report any of the rental income and don't deduct any expenses as rental expenses.
