What Is 共有產權（Tenants in Common）?
與共同共有（Joint Tenancy）不同，共有產權沒有生存者取得權——當一位共有人過世時，其份額按遺囑繼承而非自動移轉給其他共有人。這使TIC架構更適合投資合夥關係：各方可持有不同比例的份額，獨立安排自己份額的處分。在法律保護與資產架構中，選擇TIC還是共同共有取決於你的繼承規劃和退場策略。
共有產權（Tenants in Common，簡稱TIC）是一種不動產共有形式，兩人或多人各自持有一定比例的產權份額，份額可以不等，且各自可獨立轉讓、繼承或出售自己的份額。

How It Works
Core mechanics. Tenants in Common operates within the broader framework of legal strategy. When investors encounter tenants in common 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, tenants in common shows up during the invest phase of investing. For properties in markets like San Antonio, understanding this concept helps you make informed decisions about pricing, financing, or management. Most investors learn to factor tenants in common into their standard deal analysis spreadsheet alongside metrics like cash-on-cash return and DSCR.
Market context. Tenants in Common can vary significantly across markets. What works in San Antonio 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
Nadia is evaluating a property in San Antonio listed at $416,000. The property generates $2,400/month in gross rent across two units. After accounting for tenants in common in the analysis, Nadia discovers that the effective return shifts meaningfully — the initial 5.2% cap rate calculation changes once this factor is properly accounted for.
Nadia runs the numbers both ways: with and without properly accounting for tenants in common. The difference amounts to roughly $3,200/year in either additional cost or reduced income. On a $416,000 property, that is the difference between a deal that meets the 1% rule and one that falls short. Nadia 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 tenants in common assumptions with actual market data, not seller-provided projections or outdated estimates
- Market specificity: Tenants in Common behaves differently in landlord-friendly vs. tenant-friendly states, and across different property classes
- Integration risk: Do not analyze tenants in common in isolation — it interacts with financing terms, tax implications, and local market conditions
