Legacy Modernization
Phased replacement of aging property systems without freezing leasing or maintenance.
Real estate
Property software for operators who already have listings, leases, and a messy integration map.
Senior engineers for property operations and PropTech products — not an invented portfolio size or valuation accuracy rate.
Real estate software engineering for listings, operations, and the APIs in between
Real estate systems are integration problems dressed up as products: MLS/IDX feeds, lease and maintenance workflows, owner and tenant portals, and accounting next door. Maxiom delivered Yes! Communities’ property management work with Zillow API listing sync, and BrokerBlocks on the brokerage-product side. We have shipped software since 2002. We do not invent portfolio sizes, operational savings, or valuation accuracy rates for properties we do not operate.

The problem
Listings and operations as two products
A marketing site with IDX and an operations tool that does not share identity or unit data is how owners lose trust in the numbers.
Feed work underestimated
RETS, RESO, and portal APIs fail on mapping and exceptions, not on “we connected Zillow.”
Valuation and IoT as decoration
AVMs and sensor dashboards are easy to promise. Operators need lease, maintenance, and money to reconcile first.

Frequently asked questions
What real estate software does Maxiom work on?
Property operations platforms, listing and feed integrations, and owner/tenant-facing systems. Scope starts from the systems you already run — PMS, MLS, accounting — not a six-feature PropTech catalog.
Which real estate engagements are named in this repo?
Yes! Communities (manufactured housing operations and listing sync) and BrokerBlocks. Ask on a scoping call if your stack looks like theirs.
Can you integrate MLS, IDX, or RESO Web API?
Yes, when that is the listing source. Feed work is contract, mapping, and failure modes — stale listings, photo rules, office exclusions — not a checkbox.
Do you build automated valuation models?
We will scope data, features, and what accurate means for your use. We will not put an accuracy rate on a marketing page. If the job is a model, it gets a named engineer and a written evaluation, not a slogan.
Can this include owner or tenant portals?
Yes, as interfaces on top of a system of record. Portals that invent a second ledger next to accounting are how these projects fail.
Will you review AI-generated PropTech code?
Yes. AI code oversight for feed parsers, auth, and payment-adjacent paths. Client code stays in your environment.
How do real estate engagements start?
A scoping call on PMS, listing sources, accounting, and whether you need build, integration, or modernization. Written scope and NDA before access.
Who staffs the work?
Senior engineers. A named engineer owns the engagement.
