FAQ
\n\n
How does Reonomy’s Reonomy ID compare to these alternatives?
\n\n
Reonomy’s proprietary Reonomy ID was designed to resolve true ownership behind LLCs and trusts using machine learning and proprietary algorithms. Most alternatives approach ownership resolution differently—PropertyShark emphasizes verified contact research, CoStar aggregates data from multiple public sources and researchers, and CompStak relies on crowdsourced member contributions. Some platforms like ATTOM and CoreLogic focus on deed records and public data rather than ownership resolution specifically.
\n\n
Which alternative is best for deal sourcing?
\n\n
CompStak and PropertyShark excel at deal sourcing for brokers and investors who value accurate comps and verified transaction data. PropStream and BatchLeads prioritize off-market property discovery and lead generation. LoopNet and Crexi serve as marketplaces for listed deals. Your choice depends on whether you’re looking for listed opportunities, crowdsourced transaction intelligence, or off-market lead generation.
\n\n
Do any of these platforms offer APIs for integration?
\n\n
Yes, several platforms offer APIs or data feed integrations. CompStak provides an API for market rent, comps, and property data integration. PropStream and Dwellsy IQ support API and bulk data options for platform integration. CoStar and other enterprise platforms typically negotiate custom integrations through their sales teams.
\n\n
Which platform is most affordable?
\n\n
PropStream and PropertyShark generally offer more accessible pricing for individual users and smaller firms. PropStream includes free skip tracing on Pro and Elite plans, while PropertyShark’s tiered subscriptions start lower than CoStar or CoreLogic. Crexi and CompStak vary in accessibility; contact them for details. Larger enterprises typically negotiate volume discounts with CoStar, LoopNet, and ATTOM Data.
\n\n
Can I use rental data from these platforms?
\n\n
Most platforms focus on sales, lease, and ownership data. Dwellsy IQ is the primary provider of unit-level rental data for pricing and income modeling. CoStar includes lease comps, and CompStak provides lease transaction data. If you specifically need rental pricing intelligence for multifamily or single-family properties, Dwellsy IQ is the specialized choice.
