買啱第一步

The 12 risks every Hong Kong-background buyer should run before signing in Greater Houston.

香港背景買家喺大休斯頓簽合約之前一定要 run 嘅 12 個風險。

Buy It Righti.
Preface · 序

You earn on the buy, not on the sell.

錢係買嘅時候賺,唔係賣嘅時候。

This guide exists because the same questions arrive at every first conversation. Why is the property tax so high. Whether an ITIN mortgage is real. What flood zone really means. How a Buyer Representation Agreement works after 2024. Whether Cy-Fair, Katy, or Fort Bend ISD will actually serve the family.

I came to real estate from banking. The framework I use is the framework I was trained in: look at risk before opportunity, name the cost of every path, and let the client make the decision once the picture is full.

What follows is twelve risks. Each one has come up with real Hong Kong-background buyers in Greater Houston. Each is solvable. The goal of running through them is not to scare anyone out of buying. The goal is the opposite. Once you can see each risk clearly, the rest of the process is much easier.

If a section raises a question you cannot answer for your own situation, that is the right question to bring to the first call.

呢本指南係因為每一次第一次傾,同樣嘅問題又會再出現。物業稅點解咁高。ITIN mortgage 係咪真。Flood zone 真正意思係咩。2024 年之後 Buyer Representation Agreement 點運作。Cy-Fair、Katy 同 Fort Bend ISD 邊個真係啱自己家庭。

我入地產之前係做銀行嘅。我用嘅框架就係我訓練時候用嘅框架:先睇風險,再睇機會;每條路嘅代價要講清楚;客戶喺睇到完整圖畫之後先自己決定。

跟住係十二個風險。每一個都係喺大休斯頓真實香港背景買家身上出現過。每一個都係有解決方法嘅。Run 一次嘅目的,唔係嚇你唔買。目的剛剛相反。當你睇得清楚每一個風險,之後嘅流程其實會輕鬆好多。

如果有邊一節令你諗起一個自己答唔到嘅問題,呢個就係第一次傾應該帶過嚟嘅問題。

I · Flood zone04
Risk I.

Flood zone, three datasets.

水浸區,三個資料來源

English

Hurricane Harvey (2017) changed how Houston buyers think about flood risk. Tens of thousands of homes that flooded were outside the FEMA Special Flood Hazard Area on the official map. The FEMA map alone is not enough.

Three datasets together give a usable picture: the FEMA Flood Map, the Harris County Flood Education Mapping Tool, and the specific property's flood-claim history (available through disclosure forms and historic-claim databases).

The single most common buyer mistake is checking FEMA and stopping there. The map last updated in 2007 in many tracts. The county tool surfaces the actual high-water marks during Harvey and Imelda — sometimes two streets away from a "no-risk" FEMA zone.

Flood insurance. Mandatory in SFHA zones. Strongly recommended in 500-year zones. Annual premiums run $400 to $2,800 depending on elevation and structure.

Ask: did the property flood in Harvey, Imelda, or the May 2024 derecho?

廣東話

Hurricane Harvey(2017)改變咗休斯頓買家睇水浸風險嘅方式。數以萬計水浸嘅屋都係 FEMA Special Flood Hazard Area 官方水浸區以外。淨係靠 FEMA map 一份係唔夠。

三份一齊睇先有可用嘅圖畫:FEMA Flood Map、Harris County Flood Education Mapping Tool,同埋該物業嘅 flood claim history(透過 disclosure 表格同歷史 claim 資料庫攞到)。

買家最常犯嘅錯就係淨係查 FEMA,停手。FEMA map 喺好多區域最後一次 update 已經係 2007 年。County tool 顯示 Harvey 同 Imelda 期間真實嘅水位 — 有時隔兩條街已經唔同 zone。

Flood insurance。SFHA 區強制要買。500-year zone 強烈建議買。每年保費由 USD$400 到 $2,800,視乎海拔同結構。

要問:呢間屋喺 Harvey、Imelda 或者 2024 年 5 月嘅暴風雨入面有冇水浸?

II · Property tax05
Risk II.

Property-tax cash-flow math.

物業稅同現金流

English

Texas has no state income tax. Schools, county services, and infrastructure are funded by property tax instead. Effective rates in Greater Houston run 2.0 to 3.0 percent of assessed value annually.

On an $600,000 home in Cypress, that is $12,000 to $18,000 a year. Hong Kong buyers used to Hong Kong's effective rate (under 1 percent of rental value) often miscalculate by a factor of five in the first month.

The number is paid monthly through escrow alongside the mortgage. So the real monthly cost of ownership is principal plus interest plus property tax plus homeowner's insurance plus HOA. PITI-A. Not just PI.

The Homestead Exemption reduces the taxable value for owner-occupied homes. File it after closing. It can save $700 to $2,500 per year. Many first-time buyers forget.

Ask: what is the full PITI-A on this property, not just principal and interest?

廣東話

德州冇州收入稅。學區、縣政府、公共服務全部靠物業稅資助。大休斯頓嘅實際稅率每年係 2.0% 到 3.0%。

一間 Cypress $600,000 嘅屋,每年就係 $12,000 到 $18,000。香港買家慣咗香港差餉嘅實際稅率(租值 1% 以下),首個月好容易計少五倍。

個數係每月透過 escrow 同 mortgage 一齊俾。所以真正每月持有成本係 principal + interest + property tax + homeowner insurance + HOA。PITI-A,唔淨係 PI。

Homestead Exemption 可以減低自住物業嘅計稅點。Closing 之後申請。每年可以慳 $700 到 $2,500。好多首次買家會忘記。

要問:呢間屋嘅完整 PITI-A 每月係幾多,唔淨係 principal 同 interest?

III · School district06
Risk III.

School-district verification.

學區核實

English

School zones change. The address advertised as "Cy-Fair ISD" today may rezone next year. Boundaries shift based on enrollment, new school openings, and district capacity. The MLS listing is descriptive, not contractual.

The only authoritative verification is the district's own zone-finder tool, queried by the specific street address. Cy-Fair, Katy, and Fort Bend all publish these tools online.

For Hong Kong families where school zone is the primary decision driver, this is the single most important pre-offer check. Buying for a specific elementary or high school requires confirming current assignment in writing, and understanding the district's rezoning history for that street.

What to verify. Elementary, middle, and high school assignment — separately. They are often zoned to different campuses, and a child can hit a different assignment than the neighbor across the street.

Ask: has this specific street been rezoned in the last 10 years?

廣東話

學區係會變嘅。今日寫住 "Cy-Fair ISD" 嘅地址,下年可能 rezone。地界變動原因包括註冊人數、新校開幕、學區容量。MLS 上嘅資料係描述性,唔係合約。

唯一權威核實方法係用學區嘅 zone-finder tool,輸入具體街道地址查。Cy-Fair、Katy、Fort Bend 三個學區都有 online tool。

對學區為核心決策因素嘅香港家庭,呢個係 offer 之前最重要嘅一步核實。為特定小學或者中學買,要書面確認當前分配,仲要了解該街道過往嘅 rezoning 歷史。

要核實咩。小學、初中、高中嘅分配 — 分別查。三間好多時係唔同校園,街對面屋仔可能同你個小朋友讀唔同校。

要問:呢條街過去十年有冇 rezone 過?

IV · HOA, MUD, PID07
Risk IV.

HOA, PID, and MUD tax exposure.

HOA、PID、MUD 稅承擔

English

Three add-ons that buyers often discover at closing, not during the offer.

HOA (Homeowner Association): Most master-planned communities — Bridgeland, Cinco Ranch, Sienna — charge $700 to $1,800 annually. Some have transfer fees at closing. Review the HOA bylaws during option period.

MUD (Municipal Utility District): Common in newer suburbs without city water infrastructure. The MUD bond is paid through additional property tax, often $0.40 to $1.50 per $100 of valuation. This is on top of the base tax rate.

PID (Public Improvement District): Less common but present in some Katy and Fulshear developments. Adds further to the effective tax rate.

Real impact. A "2.3% property tax" advertised rate can become 3.4% effective once MUD and PID are added. On a $700K home, the difference is $7,700 a year.

Ask: what is the total effective tax rate, with MUD and PID included?

廣東話

三項額外收費,買家好多時係 closing 嗰陣先發現,唔係 offer 期間。

HOA(Homeowner Association):大部分 master-planned community — Bridgeland、Cinco Ranch、Sienna — 每年收 $700 到 $1,800。有 D 仲有 transfer fee 喺 closing。Option period 內要睇 HOA bylaws。

MUD(Municipal Utility District):新郊區冇 city water 系統嘅常見。MUD bond 透過額外物業稅償還,通常每 $100 估值收 $0.40 到 $1.50。係加喺基本稅率之上。

PID(Public Improvement District):冇咁普遍,但 Katy 同 Fulshear 部分新項目有。再加實際稅率。

實際影響。廣告寫「2.3% 物業稅」嘅,加埋 MUD 同 PID 可能變 3.4% 實際稅率。一間 $700K 屋,差 $7,700 一年。

要問:包埋 MUD 同 PID 嘅總實際稅率係幾多?

V · Option period08
Risk V.

Option period strategy.

Option period 策略

English

The option period is the buyer's most powerful tool in Texas. For a small fee (typically $100 to $500) and a typical 5 to 10 days, the buyer can terminate the contract for any reason and get the earnest money back.

This window is for: a full inspection, a sewer-scope inspection if the property is older than 20 years, a foundation evaluation given Houston's expansive clay soil, and a survey review for boundary issues.

The mistake is treating option period as a formality. It is leverage. If the inspection finds issues, the seller will often credit repairs or reduce the price, knowing the alternative is the buyer walking with their money back.

Common waivers under pressure. In hot markets, sellers ask for waived option periods. This is almost always a bad trade for HK-background buyers unfamiliar with U.S. construction. Hold the line.

Ask: what does my licensed inspector specifically look for in a Houston home of this age?

廣東話

Option period 係德州買家最強嘅工具。用一個細費(一般 $100 到 $500),喺一般 5 至 10 日內,買家可以基於任何理由終止合約,攞返 earnest money。

呢個窗口係用嚟做:完整 inspection、20 年以上舊屋嘅 sewer-scope inspection、考慮休斯頓黏土地基嘅 foundation evaluation、邊界問題嘅 survey review。

常見錯誤係將 option period 當形式。其實係 leverage。如果 inspection 揾到問題,賣家好多時會 credit 維修或者減價,因為佢哋知如果唔做,買家可以攞返錢走。

壓力下放棄。熱市場下,賣家會要求 waive option period。對唔熟悉美國建築嘅香港背景買家嚟講,呢個幾乎一定係 bad trade。守住個底。

要問:我嘅持牌 inspector 對呢個年齡嘅休斯頓屋具體查咩?

VI · Closing costs09
Risk VI.

Closing costs, all in.

Closing cost 全包

English

Closing costs in Texas typically run 2 to 4 percent of purchase price for the buyer. On a $600,000 home, that is $12,000 to $24,000 on top of the down payment.

Components include: title insurance (lender's policy is required; owner's is optional but recommended), survey, appraisal, lender origination fees, escrow setup for property tax and insurance, recording fees, and HOA transfer fees.

Some are negotiable. Seller credits — where the seller covers a portion of buyer closing costs — are legal in Texas and increasingly common in slower markets. The cap depends on loan type (3 to 9 percent of purchase price).

Cash needed at closing. Down payment plus closing costs plus prepaid escrow plus the option fee. Always have the lender produce a Loan Estimate before commitment. The LE shows the all-in cash number.

Ask: what cash will I bring to the closing table, total?

廣東話

德州買家嘅 closing cost 一般係購買價嘅 2 至 4%。一間 $600,000 屋,係首期之上再加 $12,000 到 $24,000。

組成包括:title insurance(lender 嗰份必須買,owner 嗰份可選但建議買)、survey、appraisal、lender origination fee、物業稅同保險嘅 escrow setup、recording fee、HOA transfer fee。

有 D 可以議。Seller credit — 即賣家承擔部分買家 closing cost — 喺德州合法,喺較慢市場入面越嚟越常見。上限視乎 loan 類型(購買價嘅 3 至 9%)。

Closing 嗰日要帶幾多現金。首期 + closing cost + 預付 escrow + option fee。簽約之前一定要 lender 出 Loan Estimate(LE)。LE 顯示全包現金數。

要問:我 closing 嗰日總共要帶幾多現金?

VII · Lender fit10
Risk VII.

Lender fit for HK background.

啱香港背景嘅 lender

English

Not every lender knows how to underwrite a Hong Kong-background buyer. Three paths each require a lender comfortable with that path.

Conventional with U.S. credit: Available if the buyer has at least 24 months of U.S. credit history, two years of U.S. tax returns, and stable U.S. employment. Most lenders handle this.

ITIN mortgage: For buyers without an SSN but with an Individual Taxpayer Identification Number. Down payment typically 20 to 25 percent. Rates 1 to 2 percent above conventional. Specialty lenders only.

Foreign-national loan: For buyers based outside the U.S. Down payment 30 to 40 percent. Hong Kong income and assets are accepted with documentation. Rates 1.5 to 3 percent above conventional.

The wrong lender wastes weeks. A conventional-only lender will start an ITIN file, hit underwriting friction, and quit at week three. Start with the right specialist.

Ask: how many ITIN or foreign-national files has this lender closed in the last 12 months?

廣東話

並非每個 lender 都識點 underwrite 香港背景買家。三條路各需要熟悉嗰條路嘅 lender。

Conventional 配美國信用:適用於有最少 24 個月美國信用歷史、兩年美國稅表、穩定美國工作嘅買家。大部分 lender 都做到。

ITIN mortgage:適用於冇 SSN 但有 ITIN(Individual Taxpayer Identification Number)嘅買家。首期一般 20 至 25%。利率比 conventional 高 1 至 2%。只有專門 lender 做。

Foreign-national loan:適用於住美國以外嘅買家。首期 30 至 40%。香港收入同資產有適當文件就接受。利率比 conventional 高 1.5 至 3%。

Lender 揀錯就浪費幾星期。淨做 conventional 嘅 lender 開 ITIN file,第三個禮拜 underwriting 撞牆放棄。一開始就揾啱專業 lender。

要問:呢個 lender 過去 12 個月成功 close 咗幾多單 ITIN 或者 foreign-national file?

VIII · New construction11
Risk VIII.

New construction tradeoffs.

新樓嘅取捨

English

New construction in Cypress, Katy, and Fulshear is heavily marketed to HK-background buyers. The pitch is appealing: brand new, builder warranty, energy efficient, customizable. The tradeoffs are real.

Builder incentives over price reductions. Builders rarely drop list price (it sets the comp for the rest of the community). They will throw $10,000 to $30,000 of incentives at the buyer — rate buydowns, design-center credits, closing-cost coverage. These are negotiable. Most buyers do not push hard enough.

Inspection still required. "New" does not mean "no defects." Final-walk inspections regularly find HVAC issues, missing insulation, plumbing rough-ins out of spec. Always hire an independent inspector, not the builder's.

Builder lender vs outside lender. Builders offer in-house lender incentives. Compare carefully: the headline rate is often offset by a higher origination fee or buydown that does not survive refinancing.

Ask: what incentive will be applied if I bring an outside lender?

廣東話

Cypress、Katy、Fulshear 嘅新樓對香港背景買家有大量宣傳。賣點吸引:全新、builder warranty、節能、可訂製。但取捨係真。

Builder incentive 多過減價。Builder 好少減 list price(呢個會影響成個社區嘅 comp)。佢哋會向買家提供 $10,000 至 $30,000 嘅 incentive — rate buydown、design-center credit、closing-cost coverage。呢 D 可議。大部分買家唔夠進取。

Inspection 一樣要做。「新」唔等於「冇缺陷」。Final-walk inspection 經常揾到 HVAC 問題、缺少 insulation、不合規 plumbing。永遠請獨立 inspector,唔好用 builder 推薦嗰個。

Builder lender vs 外面 lender。Builder 提供 in-house lender 嘅 incentive。仔細比較:表面利率好多時被較高 origination fee 或 buydown 抵銷,refinance 之後唔留低。

要問:如果我用外面 lender,會有咩 incentive?

IX · Reading comps12
Risk IX.

Reading the comps honestly.

誠實睇 comps

English

Comps — comparable sales — are the foundation of fair pricing. Honest comp reading is harder than it looks.

Useful comps share four attributes with the subject property: same neighborhood (not just same city), similar square footage (within 15 percent), similar year built, and closed within 90 days. Comps over six months old in a moving market are misleading.

Two adjustments matter most. Lot size: a 8,000 sq ft lot is meaningfully different from a 5,500 sq ft lot in the same subdivision. Condition: a renovated kitchen and updated HVAC adds real dollars; cosmetic-only updates add very little.

List price vs sold price. Always work from sold, not listed. Asking prices represent seller hope; sold prices represent market truth.

Ask: which three comps does my agent consider strongest, and what adjustments were made?

廣東話

Comps — comparable sales —係公平定價嘅基礎。誠實讀 comp 比表面睇難。

有用嘅 comp 同目標物業有四個共通點:同一社區(唔淨係同一城市)、相近面積(15% 以內)、相近建築年份、過去 90 天 close。喺移動市場入面,超過六個月嘅 comp 會誤導。

兩個調整最重要。Lot size:同一 subdivision 入面,8,000 平方呎地皮同 5,500 平方呎差好遠。Condition:renovated 廚房同 updated HVAC 加實際銀碼;純粹外觀 update 加好少。

List price vs sold price。永遠用 sold,唔用 list。Asking price 反映賣家希望;sold price 反映市場真相。

要問:我代理覺得邊三個 comp 最強,做咗咩 adjustment?

X · Rent vs buy13
Risk X.

Rent vs buy, full math.

租 vs 買,全數計算

English

Most "rent vs buy" math is wrong because it compares rent to mortgage payment. That is not the comparison.

The right comparison. Rent — fully expensed, no equity, no maintenance, no property tax — versus full PITI-A, plus average annual maintenance (1 to 2 percent of value), plus opportunity cost on the down payment, minus expected price appreciation, minus the principal portion of the mortgage payment (which is forced savings, not expense).

For a $600,000 Cypress home: monthly cost of ownership runs $4,400 to $5,200. Comparable rental on the same street runs $2,800 to $3,400. Buying is more expensive month-to-month for the first three to five years. The equity build, tax benefits, and appreciation only catch up over a five-plus year horizon.

The right question is not which is cheaper. It is: how long do you plan to stay, and how stable is the plan?

Ask: at my expected holding period, what is the break-even between renting and owning?

廣東話

大部分「租 vs 買」計算都係錯嘅,因為佢哋淨係比較租金同 mortgage 月供。呢個唔係正確比較。

正確比較。租金(純開支、冇 equity、冇維修、冇物業稅)vs 完整 PITI-A,加每年平均維修(樓價 1 至 2%),加首期嘅機會成本,減預期升值,減 mortgage 月供入面 principal 嗰部分(呢個係強制儲蓄,唔係開支)。

一間 $600,000 Cypress 屋:每月持有成本 $4,400 至 $5,200。同條街 comparable 租金 $2,800 至 $3,400。買頭三至五年月月貴。Equity build、稅務優惠、升值要持有五年以上先追得返。

正確問題唔係邊個平。係:你諗住住幾耐,個 plan 有幾穩定?

要問:以我預期嘅持有期計,租同買嘅 break-even 喺邊?

XI · BRA14
Risk XI.

Buyer Representation Agreement.

Buyer Representation Agreement

English

Since the August 2024 NAR settlement, Texas REALTORS® must have a signed Buyer Representation Agreement before showing MLS listings. This changed the rules for everyone.

The BRA defines four things in writing: who represents whom (the agent works for the buyer), what the agent will do, how long the engagement runs, and how the agent is paid. The buyer-paid commission piece is the most common point of confusion.

The agreement can be limited to a single property tour, a single day, a week of touring, or a longer engagement. It is not an exclusive forever contract. Hong Kong buyers nervous about commitment can sign a one-property or one-day version to start.

The buyer-paid commission piece. Many sellers still offer compensation to buyer's agents in the MLS listing. When they do, the buyer-paid amount in the BRA can be reduced or zeroed. Read this carefully.

Ask: can we start with a single-property BRA before a longer engagement?

廣東話

2024 年 8 月 NAR settlement 之後,德州 REALTOR® 喺示範 MLS 盤之前必須有買家簽咗嘅 Buyer Representation Agreement。呢個改變咗所有人嘅遊戲規則。

份 BRA 用書面定義四樣嘢:邊個代表邊個(代理為買家服務)、代理會做咩、服務期幾長、代理點收費。買家承擔佣金嗰部分係最常 confused 嘅地方。

份協議可以限制係一個物業 tour、一日、一星期 touring、或者更長期。唔係終身獨家合約。對承諾有顧慮嘅香港買家,可以由 one-property 或 one-day 版本開始。

買家承擔佣金嗰部分。好多賣家依然喺 MLS 上 offer 買家代理 compensation。佢哋 offer 嗰陣,BRA 入面買家承擔嘅數可以減或者變零。仔細讀清楚。

要問:可唔可以由 single-property BRA 開始,之後先簽長期嘅?

XII · Timeline15
Risk XII.

Timeline vs urgency.

時間表 vs 急切

English

The hardest risk to see is the one in your own head.

Real timeline drivers. Lease ending. Visa decision. Child starting school. Aging parents arriving. Promotion or relocation. Tax-year planning. These are real and they should drive the search.

False urgency drivers. "Rates might go up." "Prices might run away." "This one is unique." All three are true in some form, all three are also true at every moment in every market. None of them improves the decision quality.

The right question is not "should I buy now or later." The right question is "is my information complete enough to make a decision I can stand behind." If yes, go. If no, the next 30 days finding out are worth more than the next 30 days of urgency.

The advisor's job. Not to push timing. To name what is real urgency and what is manufactured, so the decision sits on real ground.

Ask: which parts of my urgency are real, and which are stories?

廣東話

最難睇到嘅風險,係自己腦入面嗰個。

真實時間表驅動因素。租約到期。Visa 決定。小朋友入學。父母過嚟。升職或者調職。稅務年度規劃。呢 D 係真嘅,應該推動搜尋。

虛假急切驅動因素。「利率可能升」「樓價可能跑走」「呢間係獨一無二」。三樣某程度上都係真,三樣喺每個時刻、每個市場都係真。冇一個會改善決定質素。

正確問題唔係「我而家買定遲 D 買」。正確問題係「我嘅資訊夠唔夠完整去做一個自己企得住嘅決定」。如果夠,行。如果唔夠,未來 30 日搞清楚,比未來 30 日急切更值錢。

顧問嘅工作。唔係推時機。係指出邊 D 急切係真、邊 D 係製造出嚟嘅,等決定企喺真實地基上。

要問:我嘅急切感入面,邊 D 部分係真實,邊 D 係故事?
