This is business-purpose lending. A DSCR loan qualifies the property's income, not your personal income, and it is made for investment purposes rather than as consumer credit on a home you live in. That means the qualification path is different from a consumer mortgage — and so are the disclosures. Owner-occupied purchases are not eligible.

The ratio

Rent divided by the full payment (principal, interest, taxes, insurance, HOA) is the DSCR. Meet the lender's minimum and the loan does not need your tax returns.

Naperville numbers

The 2024 ACS median value was $579,200. Rents have to be high to cover a payment on that price plus the tax bill. Larger down payments raise the ratio. Pull bills from DuPage or Will.

DSCR loans usually price above conventional investor loans, often with a prepayment penalty.

Naperville investor questions

Do DuPage and Will bills differ for Naperville rentals?
They can. Check the parcel's actual bill before you run the ratio.
Will a Naperville rental qualify with 20% down?
It depends on rent versus payment. At these prices more down is often needed.
Can I DSCR-refinance a Naperville house I moved out of?
Yes, once it is a rental with a lease.

Coverage thresholds, pricing adjustments, and prepayment structures vary by lender and change without notice. Nothing here is a rate quote, an offer, or a commitment to lend.
