Househacking can be a little complex for tax purposes.You have a primary residence in addition to a rental property.You are eligible to deduct direct and indirect expenses related to your rental property.Direct expenses can be considered items like repairing an appliance in the rental unit  or doing the flooring in the rental unit.Indirect expenses are items are items for the full house that you would pro-rate to your personal residence and your rental property.

You could always run your numbers at 5-10% below that ceiling and also factor in the additional carrying costs.

You may want to look into an accountant especially if your storage facility starts to hire employees or sell additional items like boxes and such.

It allieviates the need for an LLC (additional cost/time) and any complexities that may come in forming an LLC.

Having to completely redo the roof on a friend's addition that's only ten years old because they did this.

In addition, you may have one after a year or more of the policy being established.
