I got tired of copying Zillow listings into a spreadsheet to see if a rental makes money, so I built a Chrome extension that shows it right on the listing

Some context. I kept doing the same thing every time I looked at a listing: copy price, guess rent, guess taxes and insurance, punch it into a spreadsheet, realize it doesn't work, repeat. So I built DoorMeter. On any Zillow or Redfin listing it shows the monthly cash flow, cash-on-cash, cap rate and a 0-100 score. Rent, tax and insurance come from public data (HUD, Census, Treasury), and every number is editable and says where it came from, because the first thing anyone does

AI 分析

痛点:房产投资者在 Zillow/Redfin 看房源时,需要手动复制价格、估算租金/税费/保险到表格计算现金流,流程重复且易错。

目标用户:在 Zillow/Redfin 上筛选出租房的个人房产投资者、house hacking 买家和首次购房者。

证据:I kept doing the same thing every time I looked at a listing: copy price, guess rent, guess taxes and insurance, punch it into a spreadsheet, realize it doesn't work, repeat. ... Free for 5 listings a month, Pro is $5/mo.

变现:Freemium 订阅:每月免费 5 个房源,Pro $5/月;后续可加批量分析、报告导出、贷款/保险导流佣金。

MVP:做 Chrome 扩展,在 Zillow/Redfin 房源页注入现金流、cap rate、cash-on-cash 和评分;用 HUD/Census 公共数据做默认值,所有假设可编辑并显示来源;接 Stripe 做每月 5 次免费 + $5/月订阅。

竞品:DealCheck、BiggerPockets Rental Property Calculator、Mashvisor、Rentometer、Stessa

摘要:作者因反复把 Zillow 房源复制进表格算出租回报,做了 Chrome 扩展 DoorMeter,在房源页直接显示现金流、cap rate、cash-on-cash 和 0-100 评分。产品已上线几周,采用每月 5 个房源免费、Pro $5/月的订阅模式,但尚未给出付费用户或收入数据。痛点真实且适合独立开发者,但同类房产计算工具较多,需求强度仍需验证。
