Real estate software lives or dies on data plumbing, and most PropTech founders underestimate how much of an MVP is really integration work. A listings or brokerage product has to speak the RESO Web API and RESO Data Dictionary to pull IDX/VOW feeds from an MLS, and every MLS has its own approval process, field mappings, and display rules you must honor before you can show a single listing. We build the normalization layer that reconciles inconsistent MLS field data, dedupes across overlapping feeds, and keeps your local store in sync via replication rather than hammering the API, so the AI features on top actually have clean, current data to reason over.
The single most dangerous thing an AI real estate product can do is violate the Fair Housing Act. Any model that touches recommendations, ad targeting, tenant screening, or even the wording of listing descriptions can inadvertently create disparate impact around the protected classes, and HUD's guidance now explicitly covers algorithmic and automated systems. We design these features with the protected attributes (and their proxies like zip code, school-district language, or 'family-friendly' phrasing) excluded from the decision path, add audit logging so you can prove why a given result surfaced, and keep a human in the loop for anything that gates access to housing. That is not legal advice, but it is the architecture that keeps you defensible if a HUD complaint ever lands.
Automated valuation is the classic real estate AI use case, and doing it credibly means more than a regression on square footage. A useful AVM or CMA tool blends comparable sales, active and pending inventory, geospatial features (walkability, flood zone, transit distance), and property characteristics, then returns a confidence interval instead of a false-precision point estimate: appraisers and lenders will not trust a black box. For MVPs we typically ship a gradient-boosted baseline with SHAP-style feature attribution so a user can see which comps and adjustments drove the number, which is both a trust feature and a hedge against the model quietly drifting on a thin market.
The highest-leverage generative AI work in real estate right now is document intelligence over leases, disclosures, and offering memoranda. Commercial leases, estoppels, and CAM (common area maintenance) reconciliations are dense, non-standard, and expensive to read; a RAG pipeline that extracts key dates, escalation clauses, renewal options, and rent-roll figures, with every answer citing the exact page and clause, collapses a manual abstraction that takes hours into minutes. The engineering that matters here is chunking that respects clause and section boundaries, table extraction that survives scanned PDFs via OCR, and grounding strict enough that the model refuses to guess when a term is not in the document.
