A: Not at all. Many of our clients come to us with capital only — we help source the right property for your goals and manage the development from end to end.
A: We’re not selling you plans or construction services — we’re selling you results. As developers, we operate from the lens of ROI, timelines, and feasibility — not just design or materials.
A: We typically charge milestone-based project management or development fees. For full-cycle projects, we may also structure backend profit participation depending on deal type and risk profile.
A: Every project is different, but we underwrite conservatively and always build in multiple exit strategies. We’ll show you real pro formas during our discovery call.
A: Yes — many of our clients come to us with funds to deploy (e.g., 1031 exchange, liquid cash) but no specific property. We’ll help source deals that match your goals, handle the due diligence, and manage the project from start to finish.
A: Absolutely. If you own a property with development potential, we can step in as your project manager to oversee the design, permitting, bidding, construction, and delivery — leveraging systems built from 500+ ADU projects.
A: Most projects run 12–18 months from acquisition to final completion, depending on site conditions, permitting delays, and build complexity. We proactively manage each phase to reduce downtime and avoid costly errors.
A: It depends on your goals, but most of our full-cycle development clients bring between $500K–$2M+. For landowners seeking project management only, we work on milestone-based billing tied to the complexity and scope of your build.
A: No — HK Development does not provide financial, legal, or investment advice, nor do we offer guaranteed returns. All real estate carries risk. We act as your development partner and project manager, not as a financial advisor or fund manager.
A: Once you submit your address, we’ll conduct a free preliminary feasibility screen based on zoning, overlays, setbacks, and utilities. If your property passes our criteria, we can move into deeper due diligence and start building a tailored plan.
A: Yes. We have a clear intake and due diligence process specifically for 1031 exchange clients. We can quickly review deals, provide feasibility studies, and help structure a full-cycle development to meet your exchange deadlines.
A: Just fill out our quick intake form or book a discovery call. We’ll review your goals, whether you're bringing capital, land, or both — and we’ll let you know if it’s a fit. From there, we’ll outline the next steps to move forward with confidence.
If you have capital, property, or an idea — let’s explore whether we’re the right development partner for your goals.
