How we evaluate

Tools here are judged on whether their defaults produce an honest underwrite — not on how many features they ship. A calculator with sixty features and a zero percent default vacancy rate is worse than one with six features and conservative defaults, because you will not remember to override the defaults on every property.

The criteria

1. Do the defaults start conservative? Vacancy above zero, a management fee present whether or not you self-manage, and a capital reserve line that exists.
2. Can the exit cap rate be set independently? This input moves projected IRR more than any other. Tools that assume you sell at your purchase cap rate flatter every deal they touch.
3. Are rent growth and expense growth separate inputs?When one drives both, the model quietly expands margins each year and produces an expense ratio the property will never achieve.
4. Does it handle property tax reassessment? In California, Florida, Texas and other reassessment states, the seller's tax bill is not the buyer's tax bill.
5. Is it fast enough to use on properties you do not already like? The value of software is running real numbers on fifty listings rather than the five you have already talked yourself into.
6. Does it produce something you can hand to a lender or partner?

What we do not do

• Describe features we have not used. Where a review lacks first-hand testing of something, it says so rather than paraphrasing marketing copy.
• Publish statistics without a source and a date. Cap rate benchmarks change with the rate environment, and an undated figure is not a benchmark.
• Present a tool as flawless. Every review states where the product stops being adequate, including the one ranked first.

How this site makes money

Some links to tools are affiliate links, which means a commission may be earned if you subscribe through them at no additional cost to you. Those links are marked, and the full arrangement is set out on thedisclosure page.

Rankings are set against the criteria above before any commercial relationship is considered, and the limitations sections are written without reference to it. The practical check on this: read whether the top-ranked tool has real criticism attached. On this site it does.

Who writes this

Written by a finance professional working in institutional real estate fund accounting — IFRS reporting, SPC administration, and tax across a portfolio with over $1 billion in AUM. This site covers acquisition analysis from the perspective of someone who records what properties actually earn, against what they were projected to earn.

That vantage point is the reason this site emphasises reassessed property taxes, capital expenditure treatment, management fees, and the drift between projected and actual expense ratios. Those are the lines where a pro forma and a general ledger stop agreeing.

Corrections

Pricing, features, and affiliate terms change. If something here is out of date or wrong, it should be corrected rather than defended — the review's value depends entirely on it being accurate.
