Most clients start with underwriting or feasibility on a live opportunity, then add materials, marketing, and (where applicable) Texas brokerage representation via CBDHR or Mexico services as the project matures.
We underwrite land, multifamily, and mixed-use deals with real assumptions around rents, expenses, construction costs, and exit pricing so you can see base, upside, and downside cases before you commit major resources.
We connect the numbers to the dirt: zoning, utilities, access, comps, absorption, and product fit, then translate that into a recommended program and phasing plan that matches your capital and risk profile.
Once you move forward, we sit on the owner’s side of the table—helping you write scopes, compare bids, and keep drawings, budgets, and schedules aligned with the business plan.
Through Tantum Materials we source roofing, exterior systems, finishes and more from a vetted vendor network, coordinating deliveries around your construction schedule.
Tantum Marketing builds the story of the project—name, brand, decks, website, renders, photo, video, and campaigns—so stakeholders understand the value quickly and clearly.
For Texas transactions, real estate brokerage services—including representation, MLS listing services, negotiation, and contract-to-close activities—are provided by Coldwell Banker D’Ann Harper, REALTORS® (“CBDHR”), a Texas-licensed real estate brokerage.

We build a curated ecosystem around each project so clients and partners can work through one organized point of contact.
We are intentional about who we bring into each project. Partners are selected based on track record, communication, and alignment with the business plan—not just pricing.
For partners, Tantum can streamline intake, scope definition, and client communication.
For clients, this network means fewer calls, fewer surprises, and a smoother experience from first model to project milestones.
We offer underwriting, financial analysis, and pro formas to help you see your deal clearly before you commit. Whether you need a brand-new pro forma or a second, independent opinion on an existing one, we create or review the numbers and share our perspective so your team, investors, and buyers have more confidence. It’s especially useful for brokers who want a neutral 3rd-party review they can share with current owners and future buyers. (Planning support only – we don’t raise capital or provide investment advice.)
