Side-by-side comparison
| Question | Short-term rental DSCR | Long-term rental DSCR |
|---|---|---|
| Income the lender reads | Payout history, a market-data estimate or long-term rent, by program | A lease and/or the appraiser's market rent |
| City credential | Phoenix permit or Scottsdale/Tempe license, plus TPT | No STR license; long-term rentals still register with the county assessor (A.R.S. § 33-1902) |
| Number of wholesale programs | Fewer; some exclude STRs or certain condo projects | More |
| Operating costs | Furnishing, cleaning, platform fees and management affect real cash flow | Fewer moving parts |
| Insurance | Policy must cover STR use; Scottsdale and Tempe set a liability minimum | Standard landlord policy |
| HOA risk | Many Valley HOAs restrict rentals under 30 days | HOAs usually allow leasing, sometimes with minimums |
| Exit flexibility | Can usually switch to long-term leasing if STR does not work | Switching to STR later needs the city credential first |
Why the same house can produce two different ratios
DSCR is income divided by the full payment. The payment is the same whichever way you rent, but the income is not. Suppose a Scottsdale three-bedroom has a full payment of $3,900. On 12 months of payout history averaging $5,400, the ratio is 5,400 / 3,900 = 1.38. On long-term market rent of $3,600, it is 3,600 / 3,900 = 0.92.
The STR number looks better, but it also carries more uncertainty, more operating cost and more compliance work. Lenders know that, which is why fewer programs accept short-term income and why some ask for more reserves on STR files.

When the STR route makes sense
- The home has a strong, documented booking history, or sits where STR demand is clear and the HOA allows it.
- You are prepared for the city permit or license, TPT filings, STR insurance and active management.
- The deal still makes sense to you after cleaning, platform fees, utilities and furnishing.
When the long-term route makes sense
- The HOA restricts rentals under 30 days, or the condo project would fail an STR review.
- You want simpler operations and more program choices.
- The ratio works on market rent, and you prefer predictability over upside.

The practical approach
Many Valley investors run both numbers in the STR DSCR calculator before they buy. If the deal covers the payment on long-term rent, the short-term income is a bonus and the exit is easy. If it only works on projected booking revenue, choose a program built for that and expect more scrutiny. Either way, send the scenario and we will compare programs on both paths.
