Contractors raise prices. Crew members disappear. Henry Washington's solution: always underwrite to market-rate renovation costs, never to the discounted rates your personal contractors give you. If you get the deal done cheaper, that's upside. If your guy bails, you're not underwater.

The rehab budget section opens with Dominique's striking data point: on 70 to 80 percent of her projects, she encounters a surprise cost item exceeding $10,000 [1] — Dominique Gunderson "70–80% of flips hit $10k+ surprises: Dominique Gunderson estimates that 70 to 80 percent of her rehabs produce a surprise cost item of $10,…" 15:00 . The key reframe, she argues, is that this isn't bad luck — it's predictable, and should be systematically planned for. Her recommendation: a 10% contingency on top of the full estimated rehab cost for fully-inspected deals, rising to 20% for sight-unseen or limited-access purchases. Henry builds on this with his own rule: he always underwrites rehab costs at full market rates, never at the discounted prices his preferred contractors offer. His reasoning is practical — contractors raise prices, crews disappear, and any underwriting built on special relationships is fragile. By anchoring to market rates and adding a 10% contingency on top, he builds in a double layer of protection. Any savings from his preferred contractors become upside, not assumptions.
Dominique Gunderson has found that 70 to 80 percent of her rehab projects produce a surprise cost of $10,000 or more. The key insight: this isn't bad luck, it's predictable. Knowing surprises are coming means you can budget for them — and a 10% contingency on a fully inspected project is the floor.
Dominique Gunderson estimates that 70 to 80 percent of her rehabs produce a surprise cost item of $10,000 or more, making contingency planning essential.
For fully-inspected rehab projects, Dominique recommends a 10% contingency on top of the estimated rehab cost to cover inevitable surprises.
For sight-unseen or limited-access property purchases, Dominique Gunderson recommends doubling the contingency to 20% of the estimated rehab cost.
SiteGPT attracted over 1 million visitors and $500K in total revenue without spending a cent on paid marketing. The secret: engineering as marketing — building free tools that rank on Google.
Bhanu quit his first job after just 8 months, moved back to his parents' house to cut costs, and started building. One product sold for $250K; the next hit $10K MRR in its first month.
90% of SiteGPT's Google search traffic comes not from the main product but from ~50 free tools Bhanu built. Each tool targets a low-competition keyword and funnels users back to the paid product.
50,000 monthly visitors become 200 leads, 60 trials, and roughly 15–24 new customers per month at ~$100 average revenue each. Add a $1,700–$1,800 LTV and you have a very healthy SaaS.
Start with a blank Ahrefs search, layer in keyword filters (include term, KD < 10, volume > 1,000), list candidates in Notion, design a CTA linking to your main product, then score by volume, difficulty, build effort, and product relevance. That's the whole playbook.
Marketing feels painful for most builders. Engineering as marketing flips the script: instead of writing cold emails or blog posts, you build things — and those things rank on Google forever.
Don't spend months perfecting before launch. Ship the core feature, get real users, and let their feedback dictate the product roadmap. Premature polish is a trap.
SiteGPT launched and hit $10,000 MRR within its first month. That momentum was so overwhelming that Bhanu sold his existing SaaS, Feather, for $250,000 to free up all his time.
PropGPT launched with 20 downloads a day and strong influencer marketing but hit a ceiling at $1,000–$2,000 MRR. High download numbers masked a critical flaw: almost nobody stuck around after the free trial ended.
