Doorman -- Smarter Rental Management for Independent Landlords
If an entrepreneur "adopted" this product today, here's the realistic math.
Fermi summary
If you reach 260 paying landlords at $35/mo, that's $109k ARR - but you're charging for a product the market leader gives away free, so budget for 14% odds and plan to be net negative on cash through all of year one.
Market size (TAM)
$900.0M
~2.5M US independent landlords managing 2-20 units who are plausible software buyers × $360/yr avg property mgmt software spend
Year-1 ARR range
$20k - $350k
midpoint $110k
Investment to production
$37k
Dev: $18k for billing (Stripe), lease e-sign (DocuSign/HelloSign), AI prompt reliability hardening, and mobile-friendly UX polish. Marketing
Probability of success

Expected take-home Y1
$-26000
probability-weighted, after investment
Go-to-market motion
Content + community flywheel (BiggerPockets articles, landlord Facebook groups, YouTube 'landlord tips') → 40 trials/month → 6 closes at $35/mo avg → SEO compounds slowly over 18 months.
Key risks
- TurboTenant and Avail both offer genuinely free tiers covering rent collection, lease storage, and maintenance requests - the exact features Doorman is selling at $35/mo to the most price-sensitive buyer type in software
- AI-generated lease renewal clauses and legal notices carry real liability exposure - landlord-tenant law is hyper-local (city and county level), and one bad eviction notice in a rent-controlled city could generate a lawsuit or viral bad press
- Maintenance routing is a two-sided marketplace problem the product hasn't solved - without a vetted contractor network, 'routing' is just sending an email, and landlords will figure that out fast
