Private vs Institutional Second Mortgage: How to Choose in 2026

The phrase "second mortgage" covers three very different lender categories. Choosing between them changes your rate by up to 5%, your fees by up to 3%, and your closing speed by up to four weeks.

The Three Lender Categories

Category Examples Rate range Fees
A-lenders Banks, credit unions, monoline 6.49%–8.49% $0 lender fee
B-lenders Equitable, Home Trust, MCAP 8.49%–10.99% 0–1%
Private MICs and individual investors 9.99%–12.99% 1–3%

When Institutional Wins

  • Credit score 620+
  • Full income documentation (T4s, NOAs)
  • Closing date 3+ weeks out
  • Property is residential, urban, owner-occupied
  • Long-term hold (3–5 year term acceptable)

Institutional second mortgages amortize over 25–30 years, so the monthly payment is often half what a private lender would charge for the same loan amount.

When Private Wins

  • Credit score under 580 or active credit issues
  • Self-employed with limited paper trail
  • Need to close in under 7 business days
  • Bridge financing while a sale closes
  • Property is rural, mixed-use, or uniquely zoned
  • 12-month exit plan to refinance back to A or B

Private deals are typically interest-only with a 1- or 2-year term and a balloon payment at maturity.

The Real Cost Difference

$100,000 second mortgage, 12-month hold:

Lender Rate Lender fee Total interest + fees
Credit union 7.49% $0 $7,480
B-lender 9.49% $1,000 $10,475
MIC 10.49% $2,000 $12,485
Private 11.99% $3,000 $14,975

The gap shrinks fast on shorter holds. For a 6-month bridge to a refinance, the absolute dollar difference between B and private is often under $2,000 — sometimes worth paying for the speed.

Speed to Funding

Lender type Typical close
Credit union 3–4 weeks
Bank/A-lender 2–4 weeks
B-lender 7–14 business days
MIC 5–10 business days
Private individual 3–5 business days

Red Flags in Private Lending

Watch for any of the following — all are signs of a predatory lender:

  • Lender fees over 4%
  • Compounded interest more frequent than monthly
  • Prepayment lock-out for the entire term
  • Balloon penalties that exceed 3 months interest
  • Lender insists on a specific lawyer

A reputable broker will steer you away from these terms or use them only as a last resort with full disclosure.

Choosing Through a Broker

Always source private and B-lender deals through a licensed broker. Brokers have access to MICs and private investor networks that do not advertise to the public, and the broker is paid by the lender — not by you on most deals.
