Most investors either overpay for a subscription app they use twice a year or grab a free calculator that's too shallow to trust. There's a better path.
This review compares the four main options for real estate deal analysis in 2026: two one-time spreadsheets, one subscription app, and the BiggerPockets free calculator. The right choice depends entirely on how many deals you analyze per year and how deep you need to go.
Bottom line up front: For buy-and-hold investors analyzing one to five deals per year, a $29 one-time spreadsheet covers every calculation you need — DSCR, IRR, CoC, 2D sensitivity, and a Lender Solver. The entry paid tier of DealCheck (Plus, $10/mo) costs $120/year and $600 over five years. The math isn't close unless you need automated property data lookups for an active pipeline.

What a Real Deal Analyzer Actually Needs to Do
Before reviewing tools, it helps to know what metrics you actually need. Most investors focus only on monthly cash flow — and miss the calculation that determines whether a lender will approve the loan.
A complete deal analysis covers five things:
- Cash-on-cash return (CoC) — Your annualized cash income as a percentage of invested capital. The check on whether you're deploying equity efficiently.
- DSCR — Debt service coverage ratio. Net operating income ÷ annual debt service. Lenders require 1.20x–1.25x minimum. Running a deal at 1.08x DSCR means it won't close — no matter how good the cash flow looks.
- IRR — Internal rate of return over a 5-10 year hold. Accounts for time value of money and projected appreciation. The comparison standard if you're choosing between two deals or between real estate and other investments.
- Sensitivity analysis — How do returns change if rent comes in 10% below projection? If vacancy runs 12% instead of 5%? A deal that only works in the base case is a deal that's already off-track.
- Lender Solver (back-solve) — Given your rent projection and financing terms, what's the maximum purchase price that still clears your DSCR requirement? Prevents wasting time on offers a lender won't approve.
Most free tools only cover CoC. Apps like DealCheck cover the first four. The Lender Solver is rare — it's only useful if you understand DSCR well enough to set a target, which separates institutional underwriting from consumer-grade analysis.
The Tools, Reviewed
An 11-tab deal analyzer built with lender-style underwriting methodology — DSCR thresholds, debt service back-solves, and sensitivity tables drawn from how banks and DSCR lenders actually evaluate investment properties. Designed for investors who want to underwrite a deal the way a lender does, not just check cash flow.
What's inside (11 tabs): Deal Summary, 5-Year Cash Flow Projection, Operating Expenses, DSCR Analysis, Cash-on-Cash & IRR, 2D Sensitivity Table (16 scenarios across rent + price combinations), Rehab Budget, Lender Solver (back-solves max purchase price from DSCR target), Depreciation & Tax Shield, Refinance Analysis, and an Assumptions Audit tab that sources every input to a primary reference (IRS.gov, Fannie Mae, etc.).
The Lender Solver is the differentiator. Instead of iterating manually — enter a price, check DSCR, adjust, repeat — you set your minimum acceptable DSCR and get the exact price ceiling in one step. At 7.5% financing on a property renting for $1,800/month, the solver tells you the maximum offer price that keeps you above 1.25x. This is how lenders think. Knowing the ceiling before you make an offer prevents submitting above it.
Strengths
- Full 11-tab depth (DSCR, IRR, 2D sensitivity, Lender Solver)
- One-time $29 — no recurring cost
- Assumptions Audit tab cites all inputs
- Works in both Excel and Google Sheets
- Built for institutional-grade underwriting
Limitations
- No automated property data lookup
- No portfolio tracking across properties
- New product — no third-party reviews yet
- Manual comp research required
The most-reviewed spreadsheet deal analyzer on Etsy — 69 reviews, primarily positive — and the benchmark for what the market will pay for a quality one-time tool. Focuses on ROI and cash flow analysis, available in both Excel and Google Sheets.
The social proof is real. In a market flooded with AI-generated $1.99 templates, a seller with 69 reviews as of May 2026 with high ratings represents genuine satisfied buyers. The sale price (~$38) positions it at the quality end of the one-time market; regular price is approximately $47.
Feature depth relative to Shopfolio is unknown — the Etsy listing focuses on ROI and cash flow analysis, and doesn't explicitly list DSCR, IRR, sensitivity tables, or a Lender Solver. Investors who need those specific metrics should verify what's included directly with the seller before purchasing.
Strengths
- 69 reviews — proven social proof
- One-time purchase, no subscription
- Excel + Google Sheets support
- Established seller with track record
Limitations
- Higher price point than Shopfolio (sale ~$38, regular ~$47 vs. $29)
- Feature depth (DSCR, IRR, sensitivity, Lender Solver) not confirmed from listing — verify with seller before purchasing
The most feature-complete deal analysis app in this price range. DealCheck pulls property data, runs comparable rent analysis, supports multiple property types (SFR, multifamily, commercial, BRRRR), and manages a portfolio of deals in one dashboard. Plus ($10/mo) covers up to 50 properties. Pro ($20/mo) is unlimited.
Where DealCheck excels: active acquisition pipelines. If you're underwriting ten to twenty properties per month and need automated rent comp lookups, bulk analysis, and deal storage, the subscription cost is easy to justify. The property data saves hours of manual research per month.
Where DealCheck is overkill: the occasional investor who analyzes three deals per year. At $120/year, you're paying for features you're not using. DealCheck doesn't include a Lender Solver — the back-solve function that calculates your maximum offer price from a DSCR target.
Strengths
- Automated property data and comp lookups
- Supports DSCR, IRR, and scenario analysis
- Portfolio management across multiple properties
- Free starter tier available (current limits: verify at dealcheck.io)
- Mobile app — analyze on the go
Limitations
- $120–$240/year vs. $29 one-time
- No Lender Solver (back-solve from DSCR target)
- Costs $360 over 3 years at Plus tier
- Subscription dependency — access ends if you cancel
The most widely used free deal calculator in real estate investing. Covers the basics — cash flow, CoC return, gross rent multiplier — and outputs a clean one-page report you can share with partners or present to a lender. Good for a first-pass check on whether a property is worth deeper analysis.
What it doesn't cover: DSCR, IRR, sensitivity analysis, or any back-solve function. The analysis stops at cash flow. For an investor deciding whether to make an offer — which requires knowing what the lender will approve and how sensitive returns are to vacancy assumptions — the BiggerPockets calculator runs out of analytical depth before the question is answered.
Strengths
- Free — no cost barrier
- Clean shareable PDF report
- Good for first-pass screening
- No spreadsheet setup required
Limitations
- No DSCR analysis (lender qualification)
- No IRR calculation
- No sensitivity analysis
- No Lender Solver
- Insufficient depth for offer-stage underwriting
The Subscription Math
Cost Over Time: One-Time Spreadsheet vs. Monthly Subscription
| Timeframe | Shopfolio ($29, one-time) | DealCheck Plus ($10/mo) | DealCheck Pro ($20/mo) |
|---|---|---|---|
| 3 months | $29 | $30 | $60 |
| 1 year | $29 | $120 | $240 |
| 3 years | $29 | $360 | $720 |
| 5 years | $29 | $600 | $1,200 |
| Savings vs. one-time (5 yr) | — | $571 saved | $1,171 saved |
At three months, the spreadsheet is already cheaper. The subscription pays for itself only if the additional features — automated property data, rent comps, bulk analysis, portfolio tracking — save you enough time to justify $120+ per year.
For an investor closing one to three properties per year who runs their own comps from public data, the subscription features deliver little additional value relative to a one-time spreadsheet with full analytical depth.
Which Tool Is Right for You
You analyze 1–5 deals per year
Buy-and-hold investor, part-time landlord, building a small portfolio. You want institutional-grade analysis without paying monthly.
You want the most-reviewed option
Social proof matters to you. You want a tool other buyers have validated before committing.
You analyze 10–20+ deals per month
Active wholesaler or acquisitions professional. Automated property data and bulk analysis save hours per week.
You just want a quick first-pass check
You haven't committed to a property yet and want to know if the numbers are in the right ballpark before digging deeper.
Note on what "deal analysis" actually requires: The BiggerPockets calculator and a basic cash flow spreadsheet answer "what will I net per month." A full deal analyzer answers "should I make this offer, at this price, with this financing." Those are different questions, and only the second one prevents you from buying above lender approval thresholds.
Why DSCR and the Lender Solver Are Non-Negotiable
The most common deal analysis mistake: running numbers that show positive cash flow but a DSCR below 1.20x. The deal looks profitable. The lender rejects it. You've done due diligence on a property you can't finance.
DSCR (debt service coverage ratio) = net operating income ÷ annual debt service. Consider a property renting for $1,800/month with $900/month in operating expenses — a 50% expense ratio, which is in line with conservative real-world estimates. That produces $10,800 in annual NOI. At 7.5% on a $220,000 loan (a high purchase price relative to this rent level — intentionally used to illustrate the DSCR failure point), annual debt service is $18,459. DSCR = $10,800 ÷ $18,459 = 0.59x — well below the 1.20x floor most investment lenders require. This deal doesn't close regardless of how the cash flow looks on a basic calculator.
The Lender Solver inverts this: given $1,800 rent, $900 operating expenses, 7.5% rate, and a 1.25x DSCR target — what's the maximum price at 25% down? The solver outputs $137,000. Now you know your ceiling before you make an offer.

Frequently Asked Questions
Is a spreadsheet as accurate as a deal analysis app like DealCheck?
For individual deal underwriting — modeling cash flow, DSCR, IRR, and sensitivity — a well-built spreadsheet is equally accurate and often more transparent. Apps like DealCheck add value through property data lookups, comparable rent pulls, and portfolio management features that a spreadsheet doesn't replicate. If you're analyzing one to five deals per year without needing automated comps, a one-time spreadsheet covers every calculation you need. If you're running an active acquisition pipeline that requires pulling property data on dozens of addresses per month, a subscription app earns its cost.
What's the difference between a deal analyzer and a rental property calculator?
A rental property calculator typically projects ongoing cash flow — what you'll net per month given rent, expenses, and mortgage. A deal analyzer is broader: it starts at acquisition (purchase price, financing terms, closing costs, rehab budget) and runs through the full investment case — DSCR to confirm lender qualification, CoC return, IRR over a hold period, equity build, depreciation tax shield, and a sensitivity table showing how returns change across rent and price scenarios. The distinction matters at purchase decision time, when you need to know not just 'what will I collect' but 'should I buy at this price.'
How many deals do I need to analyze to justify a subscription deal analyzer?
At $10/month (DealCheck Plus), a subscription costs $120/year or $360 over three years. A one-time spreadsheet at $29 pays for itself vs. a subscription after about three months. If you're actively pursuing deals — making offers on five to ten properties per month and needing automated property data lookups — a subscription's additional features (comps, bulk analysis, portfolio tracking) justify the cost. If you're a buy-and-hold investor closing one to three properties per year and running your own numbers, a one-time spreadsheet is the rational choice.
What is a Lender Solver and why does it matter?
A Lender Solver is a back-solve function: instead of entering a purchase price and seeing if the deal clears DSCR, you set your target DSCR and let the tool calculate the maximum purchase price you can pay at that financing level. This matters because lenders set minimum DSCR requirements (typically 1.20x–1.25x for investment properties). Without a Lender Solver, investors manually iterate — enter a price, check DSCR, adjust, repeat. With a Lender Solver, you enter your rent projection and financing terms and get the exact price ceiling in one step.
