This second-position DSCR calculator models the capital stack you actually close: an existing first mortgage plus a new second. It is built for investors who want to pull cash without refinancing a low first-lien rate. Program caps on the second-position DSCR cash-out page are hard-wired into the results: 80% combined LTV, $125,000–$1,000,000 second, 640 FICO, and combined DSCR greater than 1.0.
Pair it with the first-lien DSCR calculator when you are sizing a purchase or a full refinance instead, and with the second vs cash-out refinance guide when you are choosing a path.
Second-position DSCR calculator
Keep your first mortgage, add a second, and see combined LTV, total PITIA, and whether rent still covers both loans. Results are estimates — not a loan offer. Second-lien pricing is quoted per file.

Program checklist
Keep the first vs. cash-out refinance
Same cash pulled, two capital stacks. Refinance comparison uses an illustrative first-lien DSCR rate you can edit.
| Keep first + second | Cash-out refi the first | |
|---|---|---|
| New first rate | — | — |
| Total debt | — | — |
| Monthly P&I (all liens) | — | — |
| Cash pulled | — | — |
What you are measuring
Combined LTV is (first balance + second amount) ÷ current value. Room for a second is whatever sits between the first-lien balance and 80% of value. If that gap is under $125,000, this program cannot fund — even if the property has equity on paper.
Combined PITIA is first-lien P&I + second-lien P&I + taxes + insurance + HOA. Taxes and insurance are counted once. Combined DSCR is gross rent ÷ that PITIA stack. The program needs a ratio greater than 1.0, meaning rent more than covers both loans and the carrying costs.
The binding max cash-out is the lower of the CLTV room and the DSCR room, then capped at the $1,000,000 program maximum. Click “Fill max cash-out” to load that number into the second-lien field.
How to read the keep-vs-refinance table
The right-hand comparison assumes you pull the same cash two ways: keep the first and add a second, or refinance the first into a new DSCR first at 80% LTV using the illustrative refinance rate. If keeping the first saves meaningful monthly P&I, the second is doing its job. If the first is already at today’s DSCR rates, a cash-out refinance is usually simpler.
First-lien DSCR rates at Jaken Finance Group still run 5.75%–10.5% on 30-year fixed or ARM products. The refinance-rate input defaults inside that band as an illustration, not a lock.
Eligible collateral on this math
The checklist flags property type because this product only finances SFR (max 10 acres), 2–4 units, warrantable condos. Switch the dropdown to “Other” to see a fail state. For condo warrantability detail see DSCR loans for condos. For first-lien mechanics that still apply to the existing mortgage, see subordination and due-on-sale.
