Free 2026 Rental Property Financing Calculator
PITI · DSCR · Break-Even Rent · Cash-on-Cash Return
Before you run a full ROI analysis on a rental property, two questions have to be answered first: What will this property actually cost you each month? and Can the rent realistically carry it? Most landlords underestimate the true monthly cost because they only think about the mortgage payment — not the full PITI (Principal, Interest, Taxes, and Insurance) that lenders and experienced investors use to evaluate deals.
FinancingFit answers both questions instantly. Enter your purchase price, loan terms, and expected rent, and the calculator shows you your full PITI payment, your DSCR (the ratio lenders use to approve investment property loans), the minimum rent needed to break even, the maximum price you can pay and still break even at current market rents, and your cash-on-cash return on the down payment.
All calculations are hard-coded with 2026 OBBBA tax rules — including the $16,100 standard deduction, the $40,400 SALT cap, and permanent 100% bonus depreciation for qualifying improvements. No spreadsheet required. No account needed. Results update live as you type.
Maintenance, management, utilities not paid by tenant
Negative — rent does not cover the mortgage. You will need to subsidize this property monthly.

Key Metrics Explained
Every number in the calculator has a specific meaning. Here is what each one tells you and why it matters before you make an offer.
P + I + Taxes + InsuranceYour total monthly obligation — not just the mortgage payment. Lenders use PITI to qualify you. Investors use it to evaluate whether rent can carry the property. Most landlords underestimate PITI by forgetting taxes and insurance.
Effective Rent ÷ Monthly PITIThe ratio lenders use to approve investment property loans. A DSCR of 1.25x means rent covers 125% of the mortgage. Below 1.0x means the property cash flows negatively. Most lenders require 1.20–1.25x minimum.
PITI ÷ (1 − Vacancy Rate)The minimum monthly rent needed to cover all holding costs, accounting for vacancy. If market rents are below this number, the property will lose money at the current purchase price.
(Annual Cash Flow ÷ Cash Invested) × 100The annual return on your out-of-pocket cash (down payment + closing costs). A 6–10% cash-on-cash return is generally considered solid for rental properties. This is the metric that tells you whether the deal is worth your capital.
How to Use the FinancingFit Calculator
Follow these six steps to get a complete picture of any rental property deal in under two minutes.
Enter the purchase price and down payment
Start with the property's asking price and your planned down payment percentage. For investment properties, most conventional lenders require 20–25% down. A larger down payment reduces your monthly PITI and improves your DSCR, but also increases the cash you need to deploy and reduces your cash-on-cash return.
Set the interest rate and loan term
Use the actual rate you have been quoted — not a national average. Investment property rates run 0.5–0.75% above primary residence rates. If you have not been quoted yet, use a conservative estimate 0.5% above current market rates. The 30-year term gives the lowest payment; shorter terms build equity faster but increase monthly PITI.
Add property taxes, insurance, and HOA
These three costs are frequently underestimated. Property taxes vary from under 0.5% of value in Hawaii to over 2% in parts of New Jersey and Illinois. Insurance for a rental property typically runs 15–25% more than a primary residence policy. HOA fees, if applicable, can range from $50 to $500+ per month.
Enter expected monthly rent and vacancy rate
Use comparable rents from Zillow, Rentometer, or local property management companies — not the listing agent's projection. For a conservative analysis, use the 10th percentile of comparable rents. A 5–8% vacancy rate (3–4 weeks per year) is a reasonable assumption for most markets.
Review the DSCR and break-even rent
A DSCR above 1.20x is the standard lender threshold for investment property loans. If your DSCR is below 1.0x, the property cash flows negatively at your entered rent. Compare the break-even rent to actual market rents — if break-even is above market, the deal does not pencil at the current purchase price.
Use the break-even purchase price to negotiate
The break-even purchase price is the maximum you can pay and still break even at your entered rent. If the asking price is above this number, you need either a lower price, a higher rent, or a different financing structure. This figure is your anchor in price negotiations.
Real Landlord Example Scenarios
Three realistic 2026 deals across different markets — showing how the same calculator reveals very different outcomes depending on location, price, and rent.
Scenario 1 — Single-Family Home, Midwest Market
Columbus, OH · $285,000 purchase price · 25% down · 7.25% rate
| Loan amount | $213,750 | Monthly P&I | $1,459 |
| Property taxes | $285/mo | Insurance | $120/mo |
| Total PITI | $1,864/mo | Expected rent | $2,100/mo |
| DSCR | 1.13x ⚠️ | Monthly cash flow | +$36/mo |
| Break-even rent | $1,964/mo | Cash-on-cash return | 0.5% |
Verdict: The deal barely cash flows positive but the DSCR of 1.13x is below the 1.20x lender threshold — this investor would need a larger down payment or a lower purchase price (~$255,000) to qualify for conventional investment financing. The 0.5% cash-on-cash return is well below the 6–8% target.
Scenario 2 — 3-Unit Building, Sunbelt City
Phoenix, AZ · $480,000 purchase price · 25% down · 7.5% rate · 3 units at $1,400/mo each
| Loan amount | $360,000 | Monthly P&I | $2,517 |
| Property taxes | $400/mo | Insurance | $220/mo |
| Total PITI | $3,137/mo | Gross rent (3 units) | $4,200/mo |
| DSCR | 1.34x ✓ | Monthly cash flow | +$463/mo |
| Break-even rent | $3,302/mo | Cash-on-cash return | 4.1% |
Verdict: The DSCR of 1.34x clears the lender threshold and the deal cash flows positively. The 4.1% cash-on-cash return is below the 8% target but acceptable for a Sunbelt market with strong appreciation potential. With 2026 OBBBA bonus depreciation on appliances and improvements, the after-tax return improves significantly in year one.
Scenario 3 — 4-Unit Building, High-Tax Coastal Area
Northern New Jersey · $750,000 purchase price · 25% down · 7.75% rate · 4 units at $2,200/mo each
| Loan amount | $562,500 | Monthly P&I | $4,025 |
| Property taxes | $1,250/mo | Insurance | $380/mo |
| Total PITI | $5,655/mo | Gross rent (4 units) | $8,800/mo |
| DSCR | 1.56x ✓✓ | Monthly cash flow | +$2,345/mo |
| Break-even rent | $5,953/mo | Cash-on-cash return | 14.8% |
Verdict: Strong deal. The DSCR of 1.56x is well above lender minimums, cash flow is $2,345/month, and the 14.8% cash-on-cash return is excellent. High property taxes ($15,000/year) are a significant cost but the 2026 SALT cap increase to $40,400 means more of those taxes are now deductible on the personal return — a meaningful improvement over the old $10,000 cap for NJ landlords.
What Landlords Are Saying
"I used FinancingFit before making an offer on a duplex. The break-even purchase price showed me I was overpaying by $22,000. I negotiated the price down and the deal now pencils."
Marcus T.
Solo landlord, 4 units, Ohio
"The DSCR gauge is exactly what my lender was asking about. I ran the numbers here first, then walked into the bank already knowing my coverage ratio. Saved a lot of back-and-forth."
Priya S.
Real estate investor, Texas
"I check this on my phone when I'm at showings. Being able to plug in the actual tax records and get a real PITI number in 30 seconds is genuinely useful."

Landlord, 7 units, Minnesota
Methodology & 2026 Tax Assumptions
The PITI calculation uses the standard amortization formula: P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1], where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of payments (term in years × 12). Property taxes are divided by 12 to get the monthly escrow component. Insurance and HOA are entered directly as monthly figures.
The DSCR is calculated as effective gross rent (gross rent × (1 − vacancy rate)) divided by total PITI. This matches the calculation used by conventional lenders and DSCR loan products. Note that some lenders use net operating income (NOI) rather than gross rent in the numerator — FinancingFit uses effective gross rent for simplicity, which is the more conservative calculation.
The $750,000 mortgage interest deduction cap reflects the Tax Cuts and Jobs Act limit, which remains in effect for 2026 for primary and secondary residences. For investment and rental properties, mortgage interest is deductible as an ordinary business expense under IRC §163 with no loan balance cap, subject to passive activity loss rules under IRC §469.
The $16,100 standard deduction for 2026 is sourced from IRS Revenue Procedure 2025-32, which sets inflation-adjusted tax parameters for the 2026 tax year. The $40,400 SALT cap reflects the OBBBA increase from the prior $10,000 TCJA cap. The permanent 100% bonus depreciation for qualifying property placed in service in 2026 is sourced from the One Big Beautiful Bill Act.
Cash-on-cash return is calculated as annual net cash flow divided by total cash invested. Total cash invested includes the down payment plus estimated closing costs (approximated at 3% of purchase price). This is a pre-tax return figure — after-tax returns will vary based on depreciation, passive activity rules, and individual tax situations.

Common Mistakes When Analyzing Rental Properties
Using gross rent instead of net rent
Gross rent is what the tenant pays. Net rent is what you keep after vacancy, repairs, and property management. A common rule of thumb is the 50% rule: assume 50% of gross rent will be consumed by operating expenses (not including mortgage). If gross rent is $2,000/month, plan for $1,000 in operating expenses and $1,000 available for debt service.
Ignoring vacancy rate
Even in strong rental markets, properties are vacant between tenants, during repairs, and during evictions. A 5–8% vacancy rate (3–4 weeks per year) is a conservative assumption for most markets. FinancingFit includes a vacancy rate input so your break-even rent reflects realistic occupancy rather than 100% occupancy.
Underestimating repair and maintenance costs
A useful benchmark is 1% of property value per year for maintenance and repairs — $2,850/year on a $285,000 property. This does not include capital expenditures like roof replacement, HVAC, or water heater, which should be budgeted separately as a reserve. Older properties require significantly more.
Confusing cash-on-cash return with cap rate
Cap rate (Net Operating Income ÷ Purchase Price) measures the property's return independent of financing. Cash-on-cash return measures the return on your actual cash invested, including the effect of leverage. Both metrics matter: cap rate tells you about the property, cash-on-cash tells you about your deal structure.
Not stress-testing the deal at higher interest rates
If you are using adjustable-rate financing or plan to refinance, run FinancingFit at your current rate and then at 1–2% higher. A deal that barely cash flows at 7.25% may cash flow negatively at 8.25%. Know your break-even rate before you commit.

Frequently Asked Questions
What is a good DSCR for a rental property?
Most lenders require a DSCR (Debt Service Coverage Ratio) of at least 1.20–1.25x for investment property loans. A DSCR of 1.25x means rent covers 125% of the mortgage payment. Below 1.0x means the rent does not cover the mortgage and the property cash flows negatively. For DSCR-specific loan products, lenders typically require 1.25x or higher.
What does PITI stand for in a mortgage payment?
PITI stands for Principal, Interest, Taxes, and Insurance — the four components of a full monthly mortgage payment. Lenders use PITI to qualify borrowers and investors use it to evaluate rental cash flow. Some properties also include HOA fees, making it PITIA.
What is the 2026 mortgage interest deduction limit for landlords?
For investment and rental properties, mortgage interest is fully deductible as a business expense under IRC §163 with no loan balance cap. The $750,000 cap applies only to primary and secondary residences under TCJA (still in effect for 2026). Rental property mortgage interest is deducted on Schedule E, not Schedule A.
How much down payment do I need for an investment property in 2026?
Most conventional lenders require 20–25% down for investment properties. A larger down payment reduces your monthly PITI and improves your DSCR, but also reduces your cash-on-cash return by increasing the cash deployed. FHA loans are not available for pure investment properties — only for owner-occupied multi-family (2–4 units where you live in one unit).
What is cash-on-cash return for a rental property?
Cash-on-cash return measures your annual pre-tax cash flow divided by your total cash invested (down payment + closing costs). A 6–10% cash-on-cash return is generally considered good for a rental property. Below 4% is weak given the risk and illiquidity of real estate. Above 12% is excellent and often indicates a strong deal or below-market purchase price.
What is break-even rent?
Break-even rent is the minimum monthly rent needed to cover your full PITI payment, accounting for your vacancy rate. If market rents are below your break-even rent, the property will have negative cash flow at current pricing. Use the break-even purchase price to find the maximum you can pay and still break even at current market rents.
How does OBBBA's 100% bonus depreciation affect rental property cash flow in 2026?
Under the One Big Beautiful Bill Act (OBBBA), 100% bonus depreciation is permanent for qualifying improvements, appliances, and personal property placed in service in 2026. This means you can deduct the full cost of a new HVAC, appliances, or renovation in the year of purchase rather than depreciating over 27.5 years. The result is a large paper loss in year one that can offset rental income and significantly reduce your tax bill — improving after-tax cash flow even when pre-tax cash flow is modest.
What is the SALT cap for landlords in 2026?
Under OBBBA, the State and Local Tax (SALT) deduction cap increases to $40,400 for 2026 (up from $10,000 under TCJA). For landlords in high-tax states like New York, California, or New Jersey, this means significantly more of your property taxes and state income taxes are deductible on your personal return, reducing your overall tax burden.
Can I use FinancingFit to evaluate a refinance on an existing rental?
Yes. Enter the new loan amount (your current balance or cash-out amount), the new interest rate, and your remaining term. Compare the new PITI against your current rent to see whether the refinance improves or hurts your cash flow and DSCR. A cash-out refinance will increase your loan amount and PITI but also increases your cash-on-cash return calculation base.
What is a good cash-on-cash return for a rental property in 2026?
Most solo investors target 6–12% cash-on-cash return. Below 4% is generally considered weak given the risk and illiquidity of real estate. Above 12% is excellent and often indicates a strong deal or below-market purchase price. In 2026, with rates still elevated, many markets produce 4–8% cash-on-cash — positive but not exceptional. Always compare to alternative investments with similar risk profiles.
How accurate are the 2026 tax assumptions in FinancingFit?
FinancingFit uses the 2026 figures from IRS Revenue Procedure 2025-32 and the One Big Beautiful Bill Act: $16,100 standard deduction, $40,400 SALT cap, permanent 100% bonus depreciation, and permanent 20% QBI deduction under Section 199A. These are the current law figures as of May 2026. Always consult a licensed CPA for advice specific to your situation.
What is the minimum DSCR lenders require for investment property loans in 2026?
Most conventional lenders require a DSCR of at least 1.20–1.25x for investment property loans. DSCR-specific loan products (which qualify based on rental income rather than personal income) typically require 1.25x or higher. A DSCR below 1.0x means the rent does not cover the mortgage and most lenders will not approve the loan without compensating factors like a large down payment or strong reserves.
