What Is 產權承諾書（Title Commitment）?
產權承諾書是成交前必須仔細審查的關鍵文件。它告訴你產權保險公司發現了哪些問題——未償還的留置權、未解除的抵押、地役權限制等——以及哪些事項不在保險涵蓋範圍內。發現問題後，你可以要求賣方在成交前解決，或決定是否繼續交易。忽視產權承諾書中的例外條款，可能在購入後才發現權利受限。
產權承諾書（Title Commitment）是產權保險公司在正式出具產權保險之前提供的初步審查文件，列明物業的產權狀況、已發現的瑕疵和例外事項，以及保險生效的前提條件。

How It Works
Core mechanics. Title Commitment operates within the broader framework of title and closing. When investors encounter title commitment in a deal, they need to understand how it interacts with other variables like operating expenses, NOI, and cap rate. The concept applies whether you are analyzing a single-family rental or a small multifamily property.
Practical application. In practice, title commitment shows up during the invest phase of investing. For properties in markets like Austin, understanding this concept helps you make informed decisions about pricing, financing, or management. Most investors learn to factor title commitment into their standard deal analysis spreadsheet alongside metrics like cash-on-cash return and DSCR.
Market context. Title Commitment can vary significantly across markets. What works in Austin may not apply in a coastal metro where cap rates are compressed and competition is fierce. Always validate your assumptions with local data and comparable transactions.
Real-World Example
Tyler is evaluating a property in Austin listed at $296,000. The property generates $2,400/month in gross rent across two units. After accounting for title commitment in the analysis, Tyler discovers that the effective return shifts meaningfully — the initial 6.4% cap rate calculation changes once this factor is properly accounted for.
Tyler runs the numbers both ways: with and without properly accounting for title commitment. The difference amounts to roughly $3,200/year in either additional cost or reduced income. On a $296,000 property, that is the difference between a deal that meets the 1% rule and one that falls short. Tyler adjusts the offer price accordingly and negotiates a $12,000 reduction, which the seller accepts after 8 days on market.
Pros & Cons
- Helps investors make more accurate deal projections by accounting for a commonly overlooked variable
- Provides a standardized framework for comparing properties across different markets and property types
- Reduces the risk of unpleasant surprises after closing by identifying potential issues during due diligence
- Gives experienced investors an analytical edge over less sophisticated buyers in competitive markets
- Can add complexity to deal analysis, especially for newer investors still learning the fundamentals
- Market-specific variations mean that rules of thumb may not apply universally across all property types
- Requires access to reliable data, which can be difficult to obtain in some markets or property categories
- Over-optimizing for this single factor can cause analysis paralysis and missed opportunities
Watch Out
- Data reliability: Always verify your title commitment assumptions with actual market data, not seller-provided projections or outdated estimates
- Market specificity: Title Commitment behaves differently in landlord-friendly vs. tenant-friendly states, and across different property classes
- Integration risk: Do not analyze title commitment in isolation — it interacts with financing terms, tax implications, and local market conditions
