PropTech Software Development Services for US & EU Developers, Brokers and Landlords
YuSMP Group builds proptech software for residential and commercial real estate operators in the US and EU: developers and homebuilders, brokerages, landlords and REITs, facility managers and ESG-reporting teams. Senior engineers deliver listing marketplaces with RESO Data Dictionary fidelity, lease and tenant portals, BIM and building-IoT integrations, and investor-facing analytics. TCPA and CAN-SPAM consent, GDPR and CCPA data subject rights, and EU CSRD ESG pipelines are part of the architecture — not a late patch.
Our PropTech practice serves four buyer profiles: developers and homebuilders running sales-office CRM, off-plan reservation and post-sale handover flows; residential and commercial brokers integrating MLS or national portals, lead distribution and TCPA-clean outreach; landlords and property managers digitizing lease, payments, work orders and tenant communications; and asset owners, REITs and facility teams needing building IoT, BIM/digital-twin integration and ESG reporting under EU CSRD. We treat TCPA, CAN-SPAM, GDPR, CCPA/CPRA and Fair Housing Act risk as engineering inputs, not legal afterthoughts.

Process
Delivery process
1. Discovery
Workshops with sales, marketing, leasing, facility and ESG teams. We map listing sources, distribution channels, building systems and reporting obligations.

RESO data model where applicable, TCPA/CAN-SPAM consent ledger, building-IoT topology and ESG data lineage map agreed before sprint one.
3. Build
Two-week sprints with RESO Certification smoke tests, accessibility gates, Fair Housing copy linting and ESG KPI calculation regression tests.
4. Launch & operate
Portal and broker rollout, leasing-team training, 24/7 on-call for payment flows, quarterly accessibility audits and CSRD data refresh cycles.

FAQ
PropTech FAQ
Do you integrate with MLS and RESO Data Dictionary?
Yes. We integrate with US MLSs using RESO Web API and RESO Data Dictionary 1.7, validate against RESO Certification expectations, and also build EU equivalents on top of national portals (Rightmove, ImmoScout24, SeLoger, idealista) where MLS does not apply.
How do you handle TCPA and CAN-SPAM in lead nurturing?
We design consent capture, DNC scrubbing, quiet-hours and revocation flows to TCPA standards (express written consent for ATDS calls and texts) and CAN-SPAM for email. EU/UK flows run under GDPR and PECR with double opt-in.
What about Fair Housing Act risk in marketplaces?
Listing copy, targeting filters and ad delivery models are HUD-sensitive. We build filter guardrails, audit logging of protected-class proxies and HUD-aligned ad audience controls to lower discrimination risk.
Can you build BIM and digital twin integrations?
Yes. We integrate with Autodesk Forge/APS, IFC 4 and bSDD for BIM data, plus building IoT (BACnet, KNX, Modbus, LoRaWAN) to power digital-twin dashboards for operations, energy and occupancy.
How do you cover EU CSRD ESG reporting?
For landlords and REITs we build ESG data pipelines mapped to ESRS E1 climate disclosures, including embodied and operational carbon, energy intensity, and EU Taxonomy alignment for buildings (DNSH, technical screening criteria).
Do you handle CCPA/CPRA opt-out signals?
Yes. We honor GPC (Global Privacy Control), build CCPA/CPRA Do Not Sell or Share workflows, age-of-consent gating and California shine-the-light notices into US-facing properties.
