Bonus is I am getting new HVAC, Furnace and hot water tank. 

More work, more time but you can take advantage of a nice cost segregation / bonus depreciationThis is the truth! 

Positive cash flow would be a bonus.

Someone I know bought a ranch to use as a short term rental property in 2021 for $1.7 million.Engineers did a virtual site visit, they were able to assign a value of $347,000 to either 5-7-15 year assets that were eligible for depreciation.In 2021, the bonus depreciation amount that you could take was 100%.This means that the owner could immediately deduct the full amount of eligible property in the year it was placed in service, rather than depreciating it over time.With that in mind, he took the full $347K deduction in his FIRST YEAR of ownership to offset taxable income from rentals.This was roughly ~20% of his purchase price.It was a big win for him.In 2024, the bonus depreciation rate is 60% so the calculation would be different.That said, you can still save and defer a ton.

New administration.As of now, 2024 bonus depreciation rate is 60%.

. :) You can't utilize bonus depreciation on anything <50% business use.

.- bonus points if I can have a separate business w/o having to pay 2x the cost, but it is what it is.- cost is an issue.
