Residential agents & brokerages
11 ideas2 easy · 6 medium · 3 hard$6K–$80K MRRMVP 4–16 weeks
Tools for the people who list and sell homes: CRM and follow-up, lead attribution, open-house capture, showing schedules, staging and pricing for listings, transaction coordination, and the brokerage back office that tracks commissions.
- How it makes money
- Per-agent subscriptions for individual tools; per-team or per-brokerage plans, and per-transaction fees for transaction management, higher up.
- Regulation: Medium
- Fair-housing and advertising rules govern listing content. Since the NAR settlement took effect on 17 August 2024, MLSs no longer carry buyer-agent compensation offers and buyers sign a written agreement before touring — the documents and workflows changed with it.
- Already owned by
- Follow Up Boss (Zillow), dotloop (Zillow), ShowingTime (Zillow), kvCORE, SkySlope, Lone Wolf
Founder's read: Agents are the largest audience and the hardest to charge one at a time, and they cut tools when a market slows. Zillow now owns the leading agent CRM (Follow Up Boss, bought in 2023), the transaction manager dotloop and ShowingTime, so an all-in-one agent suite is a fight with a portal. The durable wedge is the brokerage: commission tracking, compliance and buyer-agreement workflows sold to the owner, who buys for every agent at once.

Independent landlords
10 ideas3 easy · 6 medium · 1 hard$5K–$50K MRRMVP 4–14 weeks
Software for people who own and self-manage a handful of rentals: screening tenants, collecting rent, writing leases, tracking expenses and documents, arranging repairs and insurance — and, when it goes wrong, evictions.
- How it makes money
- Low monthly subscriptions, or free tools that earn from tenant-paid screening fees, payment processing, insurance referrals and lending.
- Regulation: Medium
- Tenant screening reports fall under the Fair Credit Reporting Act and fair-housing law, and leases, deposits and evictions follow state and city rules that differ widely.
- Already owned by
- TurboTenant, Avail (Realtor.com), Stessa (Roofstock), TransUnion SmartMove
Founder's read: A huge number of buyers with tiny budgets. The leaders give the core away and earn from tenants, payments and referrals, so a paid-only product has to beat free. Win on one painful, state-specific job — a compliant lease for one state, an eviction timeline that is actually correct — where generic tools get it wrong, and grow through landlord communities rather than paid ads.

Property managers & associations
4 ideas4 medium$8K–$50K MRRMVP 8–12 weeks
Operations software for professional managers and HOA boards running dozens to thousands of units: inspections, listing syndication, compliance deadlines and association management.
- How it makes money
- Per-unit pricing with a monthly minimum is the norm; the large suites add payments and insurance revenue on top.
- Regulation: Medium
- Local habitability, inspection and safety-certificate rules create the compliance work. For larger landlords, pricing software is now an antitrust question: the DOJ sued RealPage in August 2024, and its November 2025 settlement barred the use of competitors' real-time nonpublic data in rent recommendations.
- Already owned by
- AppFolio, Buildium (RealPage), Yardi, Entrata, HappyCo
Founder's read: Managers buy suites and resent adding point tools, so a new product has to plug into AppFolio, Buildium or Yardi rather than replace them. Inspections, compliance calendars and self-managed HOAs are where the suites are thin and switching costs are low.

Investors & short-term rental hosts
6 ideas1 easy · 4 medium · 1 hard$6K–$60K MRRMVP 4–14 weeks
Underwriting and portfolio tools for people who buy property to earn from it: deal analysis, flip and rent-to-own structuring, portfolio tracking, rent comparables, and dynamic pricing for Airbnb and VRBO listings.
- How it makes money
- Monthly subscriptions for analysis and tracking; per-listing fees or a revenue share for pricing tools.
- Regulation: Mixed
- Analysis tools need no licence; rent-to-own agreements carry consumer-protection and disclosure risk, and short-term rentals live under city permit rules that change quickly.
- Already owned by
- DealCheck, BiggerPockets, PriceLabs, Wheelhouse, Rentometer
Founder's read: Investors pay for decisions, not dashboards — a calculator is easy to copy and hard to charge for. Data is the moat: accurate local rents, expenses and comparables, or pricing that measurably lifts a host's revenue. Property records are licensed from vendors such as ATTOM and Cotality (CoreLogic until its March 2025 rebrand), so budget for data before features.

Commercial real estate & development
2 ideas1 medium · 1 hard$12K–$60K MRRMVP 10–14 weeks
Tools for brokers, owners and developers working on office, retail, industrial and new construction: lease abstraction and analytics, and project tracking from permit to handover.
- How it makes money
- Annual per-seat contracts for brokerage data and analytics; per-project or per-company pricing for construction management.
- Regulation: Low
- Few licences apply, but lease accounting under ASC 842 and lender reporting set a high bar for accuracy.
- Already owned by
- CoStar, Procore, LeaseQuery, Buildertrend
Founder's read: Far fewer buyers with far bigger budgets and longer sales cycles. CoStar dominates commercial data, so compete on workflow — turning the lease PDFs a brokerage already holds into answers — rather than on a rival database.
Homeowners & home buyers
2 ideas2 medium$8K–$35K MRRMVP 8–10 weeks
Consumer tools for people who own a home or are about to buy one: property-tax appeals and neighbourhood research before an offer.
- How it makes money
- Contingency fees on savings for tax appeals; one-off or subscription reports and referral fees for research tools.
- Regulation: Mixed
- Tax appeals follow each county's assessment calendar, and neighbourhood scores must avoid proxies that steer buyers in ways fair-housing law prohibits.
- Already owned by
- Ownwell, NeighborhoodScout, AreaVibes, Zillow
Founder's read: Consumers buy rarely, so demand is seasonal and acquisition comes from search. Property-tax appeals are the unusual consumer case with a clear return: the customer pays only out of money you save them.
