A DSCR loan lets you buy an Arizona rental on the strength of the property’s rent instead of your personal income. That makes it a favorite with self employed investors and with owners who already hold several rentals. This guide explains how the ratio works, what lenders usually ask for, how real numbers look in Phoenix and Tucson, and the Arizona rules every rental owner should know before closing.
Quick answer
DSCR stands for debt service coverage ratio: the monthly rent divided by the full monthly payment of principal, interest, taxes, insurance and any HOA dues. A ratio of 1.0 means the rent exactly covers the payment. DSCR loans are business purpose loans for rentals only, usually with no tax returns or pay stubs required, and they typically need 20% to 25% down and cost more than a conventional loan. At today’s prices, many single family homes in Phoenix and Tucson rent for less than the full payment at 25% down, so check the ratio before you make an offer.
What is a DSCR loan?
A DSCR loan is a non QM mortgage for investment property. Instead of reading your tax returns and calculating a debt to income ratio, the lender asks a simpler question: does this property’s rent cover its own payment? Because the loan is for a business purpose, it can close in your own name or in an LLC, and you cannot live in the home.
Investors use DSCR loans to buy single family rentals, condos, townhomes and two to four unit buildings, and to refinance rentals they already own. Some lenders also finance short term rentals, using either a rental history or a market rent report to estimate income.
How is DSCR calculated?
Divide the monthly rent by the monthly PITIA, which is principal, interest, property taxes, insurance and association dues. A $2,400 rent against a $2,400 payment is a ratio of 1.0. A $2,400 rent against a $2,830 payment is 0.85.
| Ratio | What it means | How lenders usually respond |
|---|---|---|
| 1.25 or higher | Rent covers the payment with room to spare | Strongest pricing and the most flexible terms |
| 1.0 to 1.24 | Rent covers the payment | Widely available at standard down payments |
| 0.75 to 0.99 | Rent falls short of the payment | Some lenders approve with more down, more reserves and a higher rate |
| Below 0.75 | Large monthly shortfall | Limited options, often only no ratio programs |
For rent, many lenders use the lower of a signed lease and the appraiser’s market rent estimate, though rules vary. On a purchase without a tenant, the appraiser’s rent schedule usually sets the number.
What do DSCR lenders usually require?
Each lender sets its own guidelines, but these ranges are common in 2026:
- Down payment: often 20% to 25% on a purchase, and more when the ratio is below 1.0.
- Credit: programs commonly start in the mid 600s, with better pricing at higher scores.
- Reserves: several months of PITIA in the bank after closing, with more required if you own several financed properties.
- Appraisal: a full appraisal with a rent schedule, since the rent drives the approval.
- Borrower: you personally or an LLC, usually with your personal guarantee.
- Occupancy: investment only. You sign a statement that neither you nor family members will live in the property.
How do the numbers look in Phoenix and Tucson?
These hypothetical examples use a 7.75% illustrative rate on a 30 year fixed loan, property taxes of 0.7% of the price a year and landlord insurance of $150 a month, with no HOA. Rents sit close to the 2027 HUD fair market rents for each area. Your rate, taxes and insurance will differ, so treat these as a way to see the math, not a quote.
| Example | Price | Rent | Down | Loan | Principal and interest | Full payment (PITIA) | DSCR |
|---|---|---|---|---|---|---|---|
| Phoenix three bedroom house | $450,000 | $2,400 | 25% | $337,500 | $2,418 | $2,830 | 0.85 |
| Same house, more down | $450,000 | $2,400 | 35% | $292,500 | $2,096 | $2,508 | 0.96 |
| Tucson three bedroom house | $360,000 | $1,950 | 25% | $270,000 | $1,934 | $2,294 | 0.85 |
| Phoenix area duplex | $520,000 | $3,400 | 25% | $390,000 | $2,794 | $3,247 | 1.05 |
Both single family examples need about 40% down to reach 1.0 at this rate. An interest only period helps: on the Phoenix house at 25% down, interest only payments of about $2,180 bring the full payment to about $2,592 and the ratio to roughly 0.93. Small multifamily often pencils out better, because two units on one lot usually bring in more rent per dollar of price than one house.
Tip: Ask for the rent schedule assumptions early. If the appraiser’s market rent comes in $150 lower than you expected, the Phoenix ratio above drops from 0.85 to about 0.80.
What Arizona rules should rental owners know?
| Topic | What applies in Arizona |
|---|---|
| Rental registration | Residential rentals, including short term rentals, must be registered with the county assessor. Out of state owners need an Arizona statutory agent, and fines can follow if you fail to register after notice. |
| Property tax | Rentals are classified separately from owner occupied homes. Both are assessed at 10%, but a rental loses the homeowner rebate of up to $600 a year, so its tax bill usually runs higher. |
| Tax on long term rent | Since January 1, 2025, Arizona cities can no longer charge transaction privilege tax on residential rentals, and there is no state or county tax on them. |
| Short term rentals | Stays under 30 days owe transient lodging tax, about 7.27% in Maricopa County and 6.05% in Pima County before city taxes, and you need a TPT license. Booking platforms usually collect it, but the owner stays responsible. |
| City permits | Cities can require a short term rental permit, an emergency contact, neighbor notice and $500,000 of liability coverage. Phoenix charges $250 a year for its permit. |
| Transfer tax | Arizona has no real estate transfer tax, and its constitution bars new ones. Buyers pay standard county recording fees, generally $30 per recorded document. |
If you are married and buy in your own name, Arizona’s community property rules usually mean your spouse signs the deed of trust even when only you are on the loan. A real estate attorney or tax professional can help you decide between personal ownership and an LLC.
Should you use a DSCR loan or a conventional investment loan?
| Feature | Conventional investment loan (Fannie Mae) | DSCR loan |
|---|---|---|
| How you qualify | Your personal income and debt to income ratio, counting 75% of the property’s market rent | The property’s rent compared with its payment |
| Income documents | Tax returns, W2 forms or pay stubs | Usually none |
| Minimum down on a purchase | 15% for one unit, 25% for two to four units | Often 20% to 25% |
| Financed properties | Up to 10 | Set by each lender |
| Who can borrow | Individuals | Individuals or LLCs |
| Rate | Lower, with pricing adjustments for investment property | Higher |
If your taxable income comfortably carries the new payment and you own fewer than 10 financed properties, a conventional loan usually costs less. A DSCR loan earns its higher rate when your returns show little income after write offs, when you want to own the property in an LLC or when you have reached Fannie Mae’s property limit.

What should you know about prepayment penalties and loan terms?
Most DSCR loans run 30 years, fixed or adjustable, and many lenders offer an interest only period that lowers the payment and lifts the ratio. Federal limits on prepayment penalties protect consumer mortgages on a home you live in, but a business purpose rental loan falls outside them, so a prepayment penalty is common. A typical structure steps down over three to five years, and choosing a shorter penalty or none usually means a higher rate.
Arizona does not add a general cap of its own, so the penalty terms in your note control. Match the penalty period to how long you expect to keep the property and the loan, especially if you might sell or refinance within a few years.
What is a step by step plan for buying a rental with a DSCR loan?
- Run the ratio on every property. Use realistic rent, a current tax estimate for a rental and a landlord insurance quote before you write an offer.
- Decide how you will own it. Form any LLC before you apply so the lender can review its documents.
- Get preapproved. Confirm your down payment, reserves and the lowest ratio the lender will accept.
- Order the appraisal with a rent schedule. Compare the appraiser’s rent with your own estimate as soon as it arrives.
- Choose the rate and prepayment terms. Line up the penalty period with your plans to sell or refinance.
- Close, then register. Register the rental with the county assessor, and get a TPT license and any city permit if you plan to rent short term.
Frequently asked questions
What DSCR do I need for an Arizona rental?
Many lenders look for 1.0 or higher, and pricing improves at 1.25 and above. Some lenders accept ratios below 1.0, or no ratio at all, with a larger down payment, more reserves and a higher rate.
Can I buy an Arizona rental in an LLC with a DSCR loan?
Yes. Most DSCR lenders will close in an LLC, usually with a personal guarantee from the owners. Form the LLC before you apply so its documents can be reviewed.
Can I use a DSCR loan for a short term rental in Arizona?
Some lenders allow it, using a rental history or a market rent report. You also need to register the rental with the county assessor, hold a TPT license and get any permit your city requires.
Do DSCR loans have prepayment penalties in Arizona?
Often, yes. Federal prepayment limits apply to homes you live in, not business purpose rental loans, and Arizona has no general cap of its own. You can usually choose a shorter penalty or none in exchange for a higher rate.
Is a DSCR loan better than a conventional loan for a rental?
Not always. A conventional loan usually costs less if your income qualifies you easily. A DSCR loan makes more sense when your write offs reduce your taxable income, when you want an LLC or when you own more financed properties than conventional rules allow.
