If you’re close to $150,000 in AGI, a few ways you can bring that down AGI is by maxing out a 401k traditional ($23k for 2024 tax year), maxing out your HSA ($4,150 for 2024 tax year), and if you have any capital losses from stocks (up to $3k per year), I would encourage you to have great bookkeeping to ensure you’re capturing all of your deductions appropriately on your rental property.

Some people don't have financial situation, nor have the bookkeeping to track or maintain it.Again, I personally find it very stressful just thinking about living that way for the life of the loan keeping the lowest daily balance possible. 

.-  Pro's:  Additional functionalities, such as tracking maintenance, automated bookkeeping, screening reports, etc. 

Some of our bookkeeping clients use it.

They are strictly taxation.If you are setting up a trust, you should get a CPA.Find a bookkeeper for your daily driver, if you find one that focuses on real estate, then during year-end your CPA won't charge you an arm and a leg.

It’s really good to have a set of eyes (you and/or a bookkeeper) to make sure each transaction is going to the right LLC and/or property and is accounted for properly.

Book keeping/tax prep costs the same.Expenses will vary depending on the market The cost of doing business varies from municipality to municipality.

Quote from @Jake Baker: @Akshay BhaskaranI have a few bookkeeping clients that invest in Columbus.

At about 30 units I added a bookkeeper, this was because it was the least enjoyable part of my REI.

It has really simplified my life on both the banking and bookkeeping fronts.
