Homestruk Deal Analyzer
Evaluate any rental property purchase in under 2 minutes.
Returns a clear BUY / PASS / CONDITIONAL verdict with math.
When to Use This Skill
- - "Is this property a good deal?"
- "Run the numbers on [address]"
- "What's the cap rate on this?"
- "Should I buy this property at $[price]?"
- Owner considering a new acquisition
- Comparing two or more deals
Required Inputs
Ask for or look up:
- - Purchase price
- Estimated monthly rent (or run homestruk-rent-comps)
- Down payment percentage (default 25%)
- Interest rate (default current 30yr rate, search if needed)
- Loan term (default 30 years)
- Closing costs (default 3% of purchase price)
- Estimated rehab/repairs needed
- Monthly expenses breakdown:
- Property taxes (search "[city] property tax rate" if unknown)
- Insurance (estimate $100-200/mo for SFR)
- Maintenance reserve (default 8% of rent)
- CapEx reserve (default 5% of rent)
- Property management (0% if self-managing, 8-10% if not)
- Vacancy rate (default 5%)
- HOA/condo fees (if applicable)
- Utilities landlord pays (if any)
Calculations
Monthly Mortgage Payment
PMT = P * [r(1+r)^n] / [(1+r)^n - 1]
Where P = loan amount, r = monthly rate, n = total payments
Key Metrics
- 1. NOI = Annual effective income - Annual operating expenses
(effective income = gross rent x (1 - vacancy rate))
- 2. Cap Rate = NOI / Purchase Price
Benchmark: 6-10% good, 4-6% acceptable, below 4% weak
- 3. Cash-on-Cash Return = Annual cash flow / Total cash invested
(cash flow = NOI - debt service)
(cash invested = down payment + closing costs + rehab)
Benchmark: 8-12%+ target, 5-8% acceptable, below 5% weak
- 4. DSCR = NOI / Annual debt service
Benchmark: above 1.25 comfortable, 1.0-1.25 tight, below 1.0 negative
- 5. GRM = Purchase Price / Annual gross rent
Benchmark: below 12 good, 12-15 fair, above 15 expensive
- 6. 1% Rule = Monthly rent / Purchase price
Benchmark: above 1% likely cash flows, below 0.7% likely negative
- 7. Price per square foot = Purchase price / Square footage
- 8. Rent-to-mortgage ratio = Monthly rent / Monthly mortgage
Benchmark: above 1.3 strong buffer, 1.0-1.3 tight
Deal Verdict Logic
STRONG BUY: cash-on-cash >= 8% AND cap rate >= 5% AND DSCR >= 1.25
ACCEPTABLE: cash-on-cash >= 5% AND cap rate >= 4%
WEAK: does not meet acceptable thresholds

在2分钟内评估任何租赁房产的购买。
返回明确的买入/放弃/有条件判断,并附有数学依据。
何时使用此技能
- - 这处房产是一笔好交易吗?
- 计算[地址]的收益数据
- 这处房产的资本化率是多少?
- 我是否应该以$[价格]购买这处房产?
- 业主考虑新的收购
- 比较两笔或多笔交易
所需输入信息
询问或查询:
- - 购买价格
- 预估月租金(或运行homestruk-rent-comps)
- 首付比例(默认25%)
- 利率(默认当前30年期利率,如需可查询)
- 贷款期限(默认30年)
- 成交费用(默认购买价格的3%)
- 预估翻新/维修费用
- 月度支出明细:
- 房产税(如未知,搜索[城市]房产税率)
- 保险(独栋住宅预估$100-200/月)
- 维护储备金(默认租金的8%)
- 资本性支出储备金(默认租金的5%)
- 物业管理费(自管为0%,否则8-10%)
- 空置率(默认5%)
- HOA/公寓物业费(如适用)
- 房东支付的水电费(如有)
计算方式
月度按揭还款
PMT = P * [r(1+r)^n] / [(1+r)^n - 1]
其中P = 贷款金额,r = 月利率,n = 总还款期数
关键指标
- 1. NOI = 年有效收入 - 年运营支出
(有效收入 = 总租金 x (1 - 空置率))
- 2. 资本化率 = NOI / 购买价格
基准:6-10%良好,4-6%可接受,低于4%较弱
- 3. 现金回报率 = 年现金流 / 总现金投入
(现金流 = NOI - 债务偿还)
(现金投入 = 首付 + 成交费用 + 翻新费用)
基准:8-12%+为目标,5-8%可接受,低于5%较弱
- 4. DSCR = NOI / 年债务偿还
基准:高于1.25舒适,1.0-1.25紧张,低于1.0为负值
- 5. GRM = 购买价格 / 年总租金
基准:低于12良好,12-15一般,高于15偏高
- 6. 1%法则 = 月租金 / 购买价格
基准:高于1%可能产生正现金流,低于0.7%可能为负
- 7. 每平方英尺价格 = 购买价格 / 建筑面积
- 8. 租金与按揭比 = 月租金 / 月按揭
基准:高于1.3缓冲充足,1.0-1.3紧张
交易判断逻辑
强烈买入:现金回报率 >= 8% 且 资本化率 >= 5% 且 DSCR >= 1.25
可接受:现金回报率 >= 5% 且 资本化率 >= 4%
较弱:未达到可接受阈值
