However, the tax treatment differs between short-term and long-term rentals:Short-Term Rentals (STRs): If you materially participate (work 100+ hours and more than anyone else on the property), you may be able to offset rental deductions against W-2 or other active income, offering greater tax benefits.Long-Term Rentals (LTRs): If your AGI exceeds $100K, your rental losses may be limited, unless you qualify as a Real Estate Professional (REPS).If you plan to expand your rental portfolio, consider an LLC later for liability protection and easier management.

And note in this I do NOT skimp on material quality.

Most of the time, the home warranty takes a long time to approve your repair, reach the property, and then they use low-quality materials.

Quote from @Ronald Rohde: I think it just benefits current owners. our replacement cost variability just went up a lot for the next 4 years. 100%.All cyclical asset classes are reverting to the mean, except the one's with a material short-- naturally. 

My wife works for Ferguson, and I know many contractors, so I can get a lot of materials at cost.

Usually I say if I have to learn something new and it will take me a long time to understand the material I say outsource because you can spend your time working on your business.

During 2020 to 2022 I was fighting to keep my business profitable as materials and labor came in short supply and eventually led to the inflation we're seeing now.

(Currently our rebar supplier is behind 2+ weeks and these materials were ordered 45 days in advance). 

Does anyone have any good studying material for this exam or have any insight on what I should focus on?

The first images of his website did not focus on real estate investments, but materialism.
