@Nicholas Aiola Thanks for the response! Much appreciated.
A few other questions.
1) I bought a property in late 2017 with the intent to rent, but I actually spent 2017 fixing up the place and didn't list it for rent until 2018. From what I understand, I can deduct mortgage interest and property taxes as if it's my secondary home, and add other expenses to the house basis price. Is this correct? Does IRS care about intent in this case? Does it matter that the property is in a different state from where I live?
2) Probably a stupid question, but is direct mail campaign costs deductible against rental income? I assumed it was before, but now that I think about it's not really related to rentals, since I can use direct mail results to either hold, flip, or wholesale.
3) I sold my primary residence last year. I rented out half of the house for only 3 months, and then spent another 5 months fixing up the place before selling it. My question is that am I obligated to deduct rental expenses during the first three months against the rental income? Or can I lump together the 3 month of rental expenses together with the repair/renovation expenses for the entire year and add it to the house basis price?
I know this is usually a stupid idea, because by moving the expenses to the house basis, I will be deducting against long term capital gain from the house sale, instead of the passive rental income which is taxed higher. But in this case, I will have extra rental income to help offset rental losses from other properties or activities that I can't deduct from W2 (since my AGI exceeded $150k) or capital gains.
