You just got a stabilized NOI and a property value from the broker. You know the next step: figure out how much debt the deal can support. LTV, DSCR, debt yield. Three constraints, one binding answer. You have done this calculation hundreds of times. The problem is not the math. The problem is that sizing the loan properly means pulling current benchmark rates, choosing the right spread, running the PMT formula across three constraints, and formatting the result into something you can hand to your principal or drop into an IC memo. That is 15 minutes of work that adds no analytical value. It is pure execution, and it competes with everything else on your plate. That’s exactly what this task is built to fix. underwriting 5 min Size Permanent Mortgage Loan Sizes the maximum permanent loan against stabilized NOI under LTV, DSCR, and debt yield constraints, anchored to current benchmark rates, with an optional interactive sizing tool. Who It’s For Acquisitions analysts, underwriters, asset managers, and brokers who need to size permanent debt against a stabilized NOI quickly and accurately. What You Get Back A professional analyst memo with the sized loan, binding constraint, key ratios, monthly debt service, and an optional interactive HTML sizing tool. Why It Matters Compresses 15 minutes of manual loan sizing into 5 minutes, anchored to live benchmark rates, so every deal gets properly sized without eating into your analytical time. Task Inputs Property Value Required The property's purchase price, appraised value, or underwritten value used for LTV sizing Stabilized NOI Required The property's stabilized net operating income Loan Terms Optional Term, fixed vs floating rate, interest-only and amortization period, etc. Include Interactive Loan Sizing Tool Required Optionally receive a downloadable, browser-based Loan Sizing Tool pre-populated with deal inputs and current benchmark rates. Open the file in any browser to adjust assumptions and re-size instantly. Lender/Program Type Optional The type of lender/program to size against (e.g., Life Co, CMBS, Commercial Bank, Debt Fund, Fannie Mae Conventional, Freddie Mac CME, FHA 223(f), FHA 221(d)(4)). Skills Used Loan Sizing Tools Used Pull Current Interest Rates What This Task Does You give the task two numbers: your stabilized NOI and property value. If you know the capital source (Life Co, CMBS, Agency, Debt Fund, FHA), you add that. If you have specific loan terms in mind (rate, amortization, IO period), you include those too. Otherwise, the task assumes institutional defaults and tells you what it assumed. From there, your Market Research Associate AI Coworker pulls current benchmark rates (Treasuries, SOFR Swaps, SOFR Daily, Prime, corporate yields, and spreads), anchors the interest rate assumption to real market data, and sizes the loan under LTV, DSCR, and debt yield constraints. It identifies the binding constraint, calculates monthly debt service, and delivers the result as a short, professional analyst memo you can hand directly to a principal or investment committee member. The whole process takes roughly 5 minutes of your time. The AI does the rest. Who This Task Is For Anyone who needs to know how much permanent debt a stabilized property can support, and needs the answer fast, with real numbers, not a back-of-the-envelope guess. This task is built for: Acquisitions analysts who need to size the debt stack on a new deal before the first underwriting pass Underwriters who want a quick sanity check on a lender quote or a refinancing scenario Asset managers who are evaluating refinance timing against current rates and constraints Brokers and capital markets professionals who need to present a realistic debt assumption to buyers or lenders on short notice In short: if you already have a stabilized NOI and property value, this task gives you a sized loan with the binding constraint identified in minutes. Why It Matters Loan sizing is one of the most fundamental calculations in commercial real estate. Every acquisition, every refinance, every capital markets pitch starts with the same question: how much debt can this property support? You already know how to answer it. You have run this analysis on dozens of deals. LTV times value. NOI divided by minimum DSCR, solve for the loan amount whose amortizing payment hits that ceiling. NOI divided by debt yield floor. Take the minimum. Done. The issue is not knowledge. It is bandwidth. Pulling current benchmark rates, choosing the right spread for the capital source, running the PMT formula correctly, and formatting the output into a clean memo takes 15 minutes. That is 15 minutes you could spend on the inputs that actually drive returns: rent assumptions, cap rate selection, renovation budgets, exit timing. When deals pile up, the sizing either gets rushed (and the rate assumption is stale, or the debt yield constraint gets skipped) or it gets delayed (and the deal sits while you finish
