Independent consulting for NYC commercial landlords — Class B & C office, industrial, and mixed-use buildings up to $50M. Over 100 buildings have grown their income by 25–300% with my guidance. Consulting only: independent advice, on demand.
Most Class B/C office, industrial, and mixed-use buildings in New York are leaving serious income on the table. I find it — then help you collect it.
Rent-roll analysis, lease restructuring, expense reduction, and repositioning — the playbook behind my clients' 25–300% income gains.
Available as a fixed-fee report.
Buy, sell, or hold — decided with data. Market analysis and capital planning built around your asset, your debt, and your horizon.
Pricing, positioning, deal structure, and negotiation counsel for transactions up to $50M — with introductions to vetted brokers when it's time to execute.
Sharpen appeal, lift occupancy, defend rents, and build the reputation that keeps quality tenants competing for your space.
A clear-eyed review of what each holding earns, costs, and could become — and a roadmap to close the gap.
When execution needs a broker, manager, attorney, or lender, I connect you to trusted specialists — and stay in your corner.
The workhorse buildings of New York — where hands-on strategy moves income the most.
The range where institutional-grade advice is rare — and where it changes everything.
New York City commercial assets only. No other markets, no distractions.
Brokers earn when you transact. Managers earn when you stay. I have no stake in either — which means my answer is never bent toward a deal you don't need.
Ratner Consulting gives NYC commercial landlords direct access to seasoned strategy on a flexible, on-demand basis. One pressing question or a full building turnaround plan — engage me for exactly what you need, for exactly as long as you need it.
When a deal is ready to execute, I introduce you to select brokers and management specialists I trust, and I remain your independent advisor throughout — confidential, precise, and answerable only to you.
Note: I do not provide brokerage or property management services. For leasing, sales execution, and day-to-day management, I partner with vetted experts so your support is seamless while my advice stays independent.
When the question is specific — a tenant wants out of half the lease, a renewal is due, a floor won't lease, you're weighing a sale — I write a report scoped to that decision. Three sizes, each with a fixed price and a fixed turnaround. No retainer, no commission on what follows.
One question, one defensible answer.
The decision worked end to end: comps, income models, the numbers to ask for, and the plan to execute.
The whole building over the next three to five years.
Submit an inquiry and I'll send the scope sheet and a sample report the same day.
No account managers, no junior analysts, no hand-offs.

A deep dive into the rent roll, expenses, leases, tenancy, and market comps — pinpointing exactly where income is leaking or hiding.
A clear, actionable plan with priorities, timelines, and projected income impact. No jargon, no padding — a plan you can act on.

Building income growth achieved by my clients — through smarter leases, tighter expenses, and sharper positioning.

"I hired David to help with a problem I had with some of my real estate bills, and with his knowledge and connections he worked it out within a couple of weeks. Just wanted to say a big thank you!
"I wouldn't have resolved the issue I had without David. Thank you so much! Highly recommended.
Slide to your building's current annual gross income and see what 25–300% growth would mean in dollars.
Illustrative only, based on results achieved across 100+ building engagements. Your building's realistic range depends on its leases, expenses, and market — which is exactly what the first conversation determines.
Practical thinking for NYC landlords — no listings, no commissions.
A maturing loan does not ask what an owner wants to do with a building. It asks what the numbers can support. Here is the hold-sell-refinance framework I run for owners before their lender runs the numbers for them.
Tenants compare effective rent, not face rent. An owner who structures the concession package deliberately wins the tenant and keeps the NOI.
A percentage-rent clause and a personal guaranty are worth nothing against a tenant who was never going to make it past year two. Here is how I underwrite retail credit before a landlord signs away frontage for a decade.
I run a boutique consulting practice for NYC commercial landlords, focused on growing building income. I advise on income strategy, investment decisions, sale and acquisition guidance, market positioning, and portfolio optimization. For brokerage or management execution, I introduce you to trusted partners — while I stay your independent advisor.
Class B and C office, industrial, and mixed-use buildings across Manhattan, Brooklyn, Queens, and the Bronx — typically valued up to $50M. These are the buildings where smart, hands-on strategy makes the biggest difference to income.
Yes — it reflects results achieved across more than 100 building engagements, driven by lease restructuring, expense reduction, occupancy gains, and repositioning. Every building is different, so the first thing I do is tell you honestly what's realistic for yours.
Sometimes. My practice is landlord representation, and that's where I spend my time. If you're a business owner reviewing a lease and want an independent read on the terms, reach out and I'll tell you honestly whether it's something I'll take on.
A broker is paid when a transaction closes, which can shape the advice you receive. I earn nothing from your transactions — no listings, no management — so my only incentive is giving you the answer that's actually right for your building.
No. My on-demand model means you engage me when you need premium advice, with no binding agreements. One call, one project, or ongoing counsel — the scope is always yours to set.
Fixed-fee reports start at $1,000 and are scoped to the decision — a lease restructuring, a renewal, a vacancy, or a hold-or-sell call. Send an inquiry and I'll reply with the scope sheet, prices, and a sample report. Hourly advisory is $200 an hour, no minimum.
Me. I lead every engagement personally. I bring 25+ years as a business owner and entrepreneur, 13+ years of daily, on-the-ground work in New York City real estate across all asset types with a focus in CRE, and over 50,000 hours of hands-on experience. I'm the one on your calls, in your numbers, and at your negotiations. No hand-offs.
One confidential conversation with David is all it takes to know whether your building can earn more. Call, text, email, or send the form.
