Frequently Asked Questions

What is self-rental?

Property owner rents to related trade or business they materially participate in. E.g., doctor owns building, rents to medical practice. Self-rental rule recharacterizes income from passive to non-passive — cannot offset unrelated passive losses.

Why problem?

Typical passive income absorbs passive losses from other rentals. Recharacterized income cannot. Self-rental preserves taxable income without offset. Reverses intended tax benefit of owning building separate from operating entity.

Work around?

Grouping election aggregating rental with related business (if trade-or-business tests met). Triple-net lease (reduces involvement, but careful — can undercut REP). Separate economic arrangement that doesn't meet related-party test. Planning with CPA.

How often should I rerun this?

Rerun this calculator whenever inputs change materially — new rent roll data, rate moves, loan balance updates, or quarterly operating data. For active deals, monthly refresh is typical. For stabilized assets under monitoring, quarterly is fine. Treat the output as a decision tool, not a one-time answer — market conditions evolve and so should your analysis.
