Yes—real-estate professionals clearly use digital tools, but there is not enough representative evidence to say how many individual investors use dedicated deal-analysis or portfolio software. The strongest current figures come from the National Association of REALTORS® (NAR), whose 2025 Technology Survey measured technology used by REALTORS® in their businesses, not by investors deciding whether to buy or hold property.
That distinction matters. A listing agent’s eSignature or drone camera is a different use case from a rental owner’s cash-flow model. You can still evaluate whether a tool is useful for your own investing, but adoption claims and product recommendations require evidence that is not established by the available reports.

What the available evidence actually measures
NAR’s “REALTORS® Embrace AI, Digital Tools to Enhance Client Service, NAR Survey Finds,” released September 18, 2025, surveyed NAR members about technology in their real-estate businesses. It found widespread use of several client-service tools:

|---|---|---|
| eSignature | 79% | REALTORS® reporting use in their businesses; not a measure of investor software adoption |
| Social media | 75% | REALTORS® reporting use; it indicates marketing activity, not deal analysis |
| Drone photography and video | 52% | REALTORS® reporting use; it concerns property presentation |
| $50–$250 monthly technology spending | 34% | Survey respondents reporting average monthly spending for a real-estate business |
| $251–$500 monthly technology spending | 20% | Survey respondents reporting average monthly business spending |
| More than $500 monthly technology spending | 24% | Survey respondents reporting average monthly business spending |
The spending figures are not budgets for rental-property calculators, investment dashboards or bookkeeping systems. They cover the respondents’ real-estate businesses and may include marketing, transaction, communication and other services. The remaining respondents reported other spending levels or did not fall into those categories; the three percentages should not be treated as a complete investor-spending distribution.
#1 Best Overall
Jessica Lautz, NAR’s deputy chief economist, said in that release: “These results show a profession that is adapting quickly to technological change while prioritizing client satisfaction.” Her statement describes the professional population NAR surveyed. It does not establish that individual investors use the same tools or use them at the same rate.
Realtor.com’s June 2025 investor report covers investor purchase and ownership activity. It helps explain the market in which investors operate, but it does not ask whether respondents use spreadsheets, calculators, property-management systems or portfolio software. Investor purchase share therefore cannot be used as a proxy for technology adoption.
What counts as a real-estate investment tool?
“Real estate investment tool” can describe several unrelated jobs. Separating them prevents a marketing or transaction tool from being mistaken for an investment-analysis system.

These organize a prospective property’s price, financing, rent, vacancy, operating expenses and expected sale assumptions. Their purpose is to decide whether a deal deserves deeper diligence. A screen is not an appraisal and does not replace inspection, title review or local legal advice.

Financing and return calculators
These model loan payments, down payment, closing costs, cash flow, capitalization rate, cash-on-cash return or an internal rate of return. Their output is only as reliable as the interest rate, amortization period, expense assumptions and timing entered by the user.
Rental operations and bookkeeping systems
Owners may use software to collect rent, track maintenance, reconcile bank activity, store leases or prepare records for an accountant. Those functions address ongoing operations rather than the initial buy-or-pass decision.
Portfolio and reporting tools
An investor with multiple properties may want consolidated debt balances, property-level profit and loss, reserve balances, tax-lot information or performance reporting. A portfolio view can reveal concentration and liquidity issues that a single-deal worksheet misses.
Market and research data
Listings, rental estimates, vacancy indicators, tax records and comparable sales can supply inputs. Data availability varies by location, and an apparently precise estimate may be stale, modeled or based on a small sample. Treat each data field as an assumption until you can verify its source and date.
How an investor might use tools from lead to decision
A repeatable workflow is more valuable than a flashy interface. The following sequence is a practical framework, not a claim about how frequently investors use any particular product.
- Define the investment case. State the property type, intended hold period, target geography, financing plan and whether the objective is income, appreciation, development or a combination. Without this, a tool can optimize the wrong metric.
- Capture primary facts. Enter the asking price, unit count, current leases, actual rent roll, property taxes, insurance, utilities, known repairs, association fees and closing-cost estimates. Label each item as verified, quoted or estimated.
- Model financing separately. Record loan amount, interest rate, term, amortization, points, lender fees and required reserves. Test the result at a higher rate or lower loan amount instead of assuming the most favorable quote.
- Project operating performance. Estimate gross scheduled rent, vacancy and credit loss, other income, operating expenses and replacement reserves. Keep capital expenditures separate from routine expenses so a new roof does not disappear inside an average maintenance percentage.
- Run scenarios. At minimum, test a base case, a downside case with lower rent or higher vacancy, and a financing case with a higher rate. Record which assumptions change and by how much.
- Verify outside the tool. Compare rent assumptions with signed leases or several local comparables, confirm taxes with the relevant government office, obtain insurance quotes and have a qualified professional review legal, tax and structural issues.
- Make a documented decision. Save the assumptions, date, source and version of the model. A clear “pass” with reasons is as useful as an approval because it prevents the same weak deal from being reconsidered without new facts.
How to judge whether a tool is worth using
There is no established ranking of named investor products in the available evidence. You can compare any tool against these practical criteria:
| Evaluation question | What to inspect | Why it matters |
|---|---|---|
| Does it fit the job? | Deal screening, operations, bookkeeping, portfolio reporting or another defined task | A tool built for agents or marketing may not calculate investment returns |
| Are assumptions visible? | Editable rent, vacancy, expense, financing, sale and tax inputs | Hidden defaults can produce an attractive but uncheckable result |
| Can calculations be audited? | Formula details, downloadable data and a way to reproduce outputs | Independent checking catches unit, timing and sign errors |
| Does it support your property and location? | Single-family, multifamily, commercial or land features; local taxes and currency | A generic template may omit expenses that apply to your asset |
| What does it cost over time? | Free limits, recurring fees, exports, user seats and cancellation terms | A low introductory price can become an ongoing operating expense |
| How are data and privacy handled? | Data retention, sharing, backups, permissions and export options | Leases, bank records and tenant information require careful handling |
Spreadsheet, software or professional review?
The right choice depends on transaction volume and complexity, not on whether a tool looks sophisticated.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
| Approach | Strengths | Limitations | Good fit |
|---|---|---|---|
| Custom spreadsheet | Transparent formulas, low cost, flexible assumptions and easy scenario testing | Manual data entry, version-control risk and limited automation | Occasional acquisitions or investors who want to see every calculation |
| Dedicated software | Repeatable workflows, imports, dashboards and centralized records | Recurring cost, learning curve and possible black-box formulas | Frequent transactions or a growing portfolio with consistent data |
| Accountant, analyst or property manager | Experience with tax, operations, local practice and review of unusual cases | Professional fees and the need to communicate assumptions clearly | Complex ownership, partnerships, renovations or significant compliance exposure |
These approaches can be combined. For example, an investor might screen deals in a simple worksheet, use an operations system after closing and have an accountant review the records. Paying for software does not remove the need to understand its inputs.

Build a checkable deal-analysis model
A defensible model starts with a small set of clearly defined lines. Use the same period—usually a month or year—throughout and keep one-time costs separate from recurring operations.
Income and operating lines
- Gross scheduled rent: the rent if every unit paid in full.
- Vacancy and credit loss: a deduction based on local evidence and the property’s condition, not a universal percentage.
- Other income: parking, laundry or fees only when they are legally permitted and reasonably supportable.
- Operating expenses: taxes, insurance, utilities paid by the owner, repairs, maintenance, management, association dues and ordinary administrative costs.
- Replacement reserves: a planned amount for roofs, heating systems, appliances and other long-lived components.
Core calculations
- Net operating income (NOI) = effective gross income minus operating expenses. Debt payments and income taxes are not operating expenses in the conventional NOI definition.
- Capitalization rate = NOI divided by purchase price or another clearly stated value. Identify which value you used.
- Cash flow before tax = NOI minus debt service and recurring capital contributions.
- Cash-on-cash return = annual cash flow before tax divided by total cash invested, including the down payment and applicable closing or initial-repair costs.
These formulas describe a model; they do not forecast a guaranteed result. A tool that reports a single return without showing vacancy, reserves, financing and timing deserves extra scrutiny.
Inputs that commonly change the answer
- Whether management is self-performed or priced at a market rate.
- Insurance availability and renewal pricing for the property’s location.
- Property-tax reassessment after purchase.
- Deferred maintenance discovered during inspection.
- Lease expirations, concessions, delinquency and restrictions on rent increases.
- Sale costs, taxes and the time required to sell when calculating a longer-term return.
How to test a tool before trusting its output
- Recreate a simple example by hand. Enter round numbers and confirm that payment, NOI and return formulas behave as expected.
- Change one input at a time. Increasing vacancy should not increase cash flow; increasing the interest rate should not reduce debt service.
- Check units and timing. Confirm whether a field is monthly or annual, nominal or percentage, per unit or for the whole property, and whether costs occur at closing or during operations.
- Export and archive. Keep a copy of inputs and outputs in a format you can read without the software. Record the date and any data source used.
- Compare with an independent calculation. A second spreadsheet, lender amortization schedule or accountant’s review can expose formula errors.
- Test an adverse case. If a modest rent reduction, vacancy increase, repair bill or rate change makes the investment unworkable, that sensitivity belongs in the decision record.
Costs, access and data safeguards
Tool pricing is not established for a representative investor population, so avoid treating NAR’s business-spending figures as a market price guide. Before subscribing, identify whether the fee is one-time or recurring, whether data exports are restricted, and whether additional properties or users cost more. A free calculator can be adequate for a single screen; a growing portfolio may justify automation only when it saves more time or error risk than it costs.
Protect account credentials and tenant information. Use strong, unique passwords and multi-factor authentication where available, limit staff permissions, and avoid uploading documents that the service does not need. Keep an offline or independent backup of financial records, leases and the assumptions behind major investment decisions.

Common mistakes and practical fixes
Confusing agent technology with investor technology
eSignature, social media and drone video help market and transact property. They do not show that investors use underwriting or portfolio tools. Fix: ask what population a statistic measured and what job the technology performs.
Accepting default assumptions
Defaults for vacancy, repairs, management or appreciation may not fit the property. Fix: replace each default with a documented local estimate and run a downside case.
Mixing operating and financing costs
Combining debt service with NOI or omitting reserves can make returns appear stronger. Fix: keep operating performance, financing and one-time capital costs on separate lines.

A result shown to two decimal places is still an estimate if rent, taxes or repairs are uncertain. Fix: show ranges, record confidence in each input and explain what would change the decision.
Failing to preserve the decision trail
Changing assumptions without saving prior versions makes later review difficult. Fix: date every model, preserve the original listing and inspection inputs, and note why an assumption changed.
What can reasonably be concluded
Digital technology is demonstrably embedded in professional real-estate work: NAR’s 2025 survey reports high use of eSignature, social media and drone imagery among REALTORS®. That is useful context, but it is not an investor-adoption study. Realtor.com’s 2025 investor report describes buying and ownership activity, not software behavior.
So the accurate answer to “Does anyone use real estate investment tools?” is yes, some investors plainly do, and many professionals use digital tools around transactions and client service. The available evidence cannot supply a representative percentage, identify a universally used investor product or prove that a particular tool improves returns. Choose a tool by the job it performs, the assumptions it exposes and your ability to verify its calculations—not by an agent-technology statistic.
