@Jean118 Hi there. I don't know how Tax calculations work in the USA, but over here in the UK there's a range of items for which one can claim, and other items one cannot (until you sell the property)
Your Tax Advisor should be able to advise you what you will and won't be able to claim for, whilst the property management company should be able to let you have a breakdown of what they're charging you.
Although depending upon how complicated or not your income from holiday lettings is, you might find that an accountant would be better for you than a tax advisor, as accountants' not only account, but they usually know all of the ins and outs of Tax Forms, requirements, etc.
Okay, so going through an Accountant might be more expensive $s-wise than doing it yourself, but then again, they're more likely to get everything right, might be able to claim for other items you hadn't considered, might even save you money, but most of all, if you're not used to the intricacies of completing Tax Returns for doing what you're doing and you don't get your sums right, you might have a tax inspector (or equivalent in the US) digging more into your financial affairs.
Whatever you decide to do, here's wishing you the best of luck!
