Quick answer
A DSCR HELOC is a line of credit you draw against over time. A DSCR second mortgage is one lump sum. Both qualify on the property's rent and sit behind your existing first mortgage.
A DSCR HELOC gives you a line of credit against a rental property, drawn as needed. A DSCR second mortgage gives you one lump sum. Both sit behind your existing first mortgage, and both qualify on the property's rent instead of your personal income. For the basics on how these work, see my DSCR HELOC page.
Side by side comparison
| DSCR HELOC | DSCR Second Mortgage | |
|---|---|---|
| How funds arrive | A line of credit you draw against over time | One lump sum at closing |
| Repayment | Payments track what you have drawn | Fixed payment on the full amount from day one |
| Best for | Ongoing or uncertain funding needs, like a renovation with a moving budget | A known, one time need, like a down payment on another property |
| First mortgage | Stays in place | Stays in place |
| Qualification | Property rent, not personal income | Property rent, not personal income |
| Flexibility | Draw and repay repeatedly during the draw period | One time funding, then a standard repayment schedule |
When a DSCR HELOC fits
A DSCR HELOC makes sense when you do not know the exact amount you will need, or when the need will come in stages. Clients doing a renovation with a budget that could shift, or building up reserves for future purchases, tend to like the flexibility of drawing only what they use.
When a DSCR second mortgage fits
A DSCR second mortgage makes more sense when you know the amount you need up front. If you are pulling out a set sum for a down payment on another rental or a specific project cost, a lump sum with a fixed payment can be simpler to plan around than a line of credit.
Neither fits? Consider a cash out refinance
If you would rather have one loan instead of two, a DSCR cash out refinance replaces your first mortgage and pulls equity out in the same transaction. It gives up the option of keeping your current first mortgage in place, so it depends on how that first mortgage compares to what you would replace it with.
