Hard Money Loan Calculator 2026 | Fix-and-Flip & BRRRR Deal Analyzer
Underwrite the complete capital stack, not just the interest rate. This underwriting engine estimates your origination points, exact Cash-to-Close, monthly holding costs, construction draw schedule impacts, DSCR cash-out refinance viability, and net ROI. It also stress-tests your Maximum Allowable Offer (MAO) against timeline delays, cost overruns, and ARV appraisal shortfalls.
Enter purchase, rehab, financing, and exit assumptions to estimate monthly carry, capital required, refinance feasibility, sale profit, downside sensitivity, and maximum safe offer price.

How Our Pro Forma Underwriting Engine Models Your Cash-on-Cash ROI
This tool walks you through a full hard money underwrite in three input cards. Each step builds on the last — enter your acquisition terms, project details, and exit assumptions to generate a survival verdict, carry cost schedule, refinance check, and downside stress test in seconds.
Decoding the Term Sheet: ARV, Points & Private Lender Jargon
Hard money lending uses specialized terminology that differs from conventional mortgage underwriting. Here are the critical terms used in this analyzer and why each one matters to your deal economics.
Real Estate Investor (REI) Case Studies: Flip vs. Refinance
Three common deal scenarios investors encounter — from a clean profitable flip to a stressed project with overruns. Use these as benchmarks when entering your own numbers.
The Deal: An investor purchases a distressed single-family home in a growing Sunbelt suburb for $240,000 with a $55,000 rehab budget. A hard money lender finances 85% LTC at 12% interest-only with 2 points on a 9-month term.
The Execution: Renovation completes in 3.5 months, the property hits the market, and closes in month 7. Sale price lands at $375,000 against an ARV of $385,000. Selling costs run 7%. Monthly holding costs are $1,400.
The Outcome: Total carry costs remain well below projections. The deal clears the MAO threshold with margin to spare. Even under a 10% ARV downside stress test, the sale exit stays profitable — validating the purchase price as a clean deal worth executing.
The Deal: An investor targets a value-add rental property — a duplex purchased for $310,000 needing $80,000 in renovations. The strategy is a BRRRR exit: stabilize, rent, then refinance into a 30-year DSCR loan at 8.0% APR.
The Execution: Hard money is at 13% IO with 2.5 points, 85% LTC. Rehab runs 5 months. Both units are rented at $1,800/month each, producing $3,600/mo gross NOI. The DSCR lender requires 1.20x and lends up to 75% LTV.
The Outcome: With a stabilized ARV of $480,000, the refi loan covers 75% = $360,000 — enough to retire the hard money loan and leave minor cash-in. DSCR hits 1.31x, clearing the lender threshold. The investor retains the asset with minimal cash trapped.
The Deal: An investor acquires a distressed Victorian rowhouse for $295,000 with a $120,000 renovation budget — scope was aggressive from day one. Hard money at 13.5% IO, 3 points, 85% LTC on a 12-month term.
The Execution: Contractor issues add 20% overrun ($24,000 extra). The sale is delayed by 4 months beyond the loan term, triggering a 1.5% extension fee and a 2% rate step-up. The market softens, dropping the sale price 8% below projections.
The Outcome: The combined stress scenario — overrun + delay + price drop — pushes cash to completion past 40% of project cost. The estimated sale profit goes negative in the stress case. The deal is technically survivable at base case only because the original ARV margin was adequate — but it is now a Capital Trap if any one more variable moves against the investor.
Pro Investor Tips: Surviving High-Interest Private Capital
Experienced hard money investors know the real danger isn’t the interest rate — it’s the cost of time. These field-tested strategies help you control carry, protect your exit, and avoid the traps that kill margins.
Always Underwrite to the MAO (Maximum Allowable Offer)
The MAO formula gives your ceiling, not your offer. Build in at least a 5–8% additional buffer below MAO for unknown carry costs, permitting delays, and lender conditions. If you can’t hit your numbers 10% below MAO, the deal isn’t worth pursuing at that entry price.
Best PracticeTime is Your True Interest Rate: Managing Holding Costs
At 12% annually, every extra month costs you 1% of your loan balance. A 3-month delay on a $350,000 loan adds $10,500 in interest alone — before extension fees or rate step-ups. Speed of execution is a profit driver, not just a schedule preference.
Watch OutPre-Qualify Your DSCR Refinance Lender Before Closing
If your exit strategy is a BRRRR refinance, speak to 2–3 DSCR lenders before closing on the property. Confirm their LTV cap, DSCR minimum, prepayment penalty, and seasoning requirement. Some lenders require 3–6 months of rental history before they will refinance — a fact that could add months of extra carry.
Best PracticeModel Construction Draw Timing Conservatively
Many investors default to 50% draw timing, but in practice, lenders release draws reactively — after inspections, not before. If your contractor needs payment upfront to start each phase, you may have 70–80% of the rehab budget outstanding on average. A higher draw timing factor increases your accrued interest and your cash-to-completion figure.
Common MistakeStress-Test Every Deal Before You Sign
Run the stress case with at least a 10% overrun, 2–3 month delay, and 8% ARV downside as your minimum assumptions — even on deals that look solid. If the stress case is a Capital Trap, you need a lower purchase price, a smaller rehab scope, or a different exit strategy before proceeding.
Risk ManagementKeep a 10–15% Liquidity Buffer for Cost Overruns
The most common way hard money deals fail is not bad math — it’s running out of accessible cash mid-project. Keep 10–15% of the total project cost in liquid reserves, separate from your project capital. This covers draw timing gaps, lender condition delays, and overruns without forcing an emergency extension or a distressed sale.
Capital SafetyNegotiating Origination Points vs. Interest Rates
On a short 6–8 month flip, points have a much larger impact on your all-in cost than the headline interest rate. A lender charging 11% with 3 points on an 8-month deal costs more than one charging 13% with 1.5 points. Always calculate total capital cost — not just monthly carry — before choosing a lender.
Negotiation TipRemember: ARV is an Appraisal Opinion, Not a Guarantee
Your ARV estimate drives nearly every metric in this analyzer. A single comparable sale that doesn’t translate to your property, an appraisal that comes in low, or a market-wide softening can destroy a deal that looked bulletproof on paper. Always build in an 8–10% ARV haircut in your stress test and confirm your comps are within 0.5 miles and 6 months.
