Investment Property Mortgage Requirements in 2026

Investment property mortgages in 2026 carry meaningfully tighter requirements than owner-occupied loans — higher down payments, higher credit-score floors, mandatory reserves, and rate premiums of 50–125 bps. The good news is that the rules are predictable. Once you know exactly what each lender will demand, you can prepare a clean file and avoid the underwriting friction that derails roughly a third of first-time investor applications.

This guide is the playbook: every requirement, by loan type, with the 2026-specific thresholds and the small overlay differences that catch most borrowers off guard.

How This Guide Works

We pulled current underwriting guidelines from Fannie Mae, Freddie Mac, and the top 10 non-QM/DSCR investors operating in February 2026. Where lenders impose overlays beyond the agencies’ base requirements, we noted the strictest version most borrowers will encounter. Rates and reserve requirements reflect Q1 2026 market conditions.

Requirement	Conventional Investment	DSCR Loan	Portfolio Bank
Min FICO	680 (740 best pricing)	660	680
Min Down Payment	20% (1-unit) / 25% (2-4)	20–25%	25–30%
Income Docs	Full doc (W-2, returns)	None	Bank statements
Min DTI	45% (50% in some cases)	N/A	50%
Reserves	2–6 months PITIA per property	6 months PITIA	6–12 months
Max Properties	10 financed (Fannie limit)	Unlimited	Unlimited
Rate Premium vs O/O	+0.50–0.75%	+1.00–1.50%	+0.75–1.25%

Credit Score Requirements

Conventional Fannie/Freddie investment loans technically allow scores as low as 620, but practical originations require 680+ to clear standard pricing and 740+ for the best rates. Below 680, expect either rejection or aggressive add-on points.

DSCR programs are more lenient — Kiavi, Visio, and RCN all originate down to 660. Rate add-ons increase below 700.

Portfolio bank loans usually require 680+, with relationship pricing for borrowers who maintain deposits or other accounts.

Down Payment Requirements

The standard 2026 down payment grid:

• 1-unit investment: 20% (Fannie), 25% (most DSCR), 25–30% (portfolio)
• 2-4 unit investment: 25% (Fannie), 25% (DSCR), 25–30% (portfolio)
• Cash-out refinance: 25% equity remaining (75% LTV) on most products
• STR-specific DSCR: 25–35% down depending on market

Higher down payments unlock better rates. 30% down on a DSCR loan typically saves 25–50 bps versus 20%.

Reserve Requirements

Reserves are the silent killer of investor pre-approvals. Fannie Mae requires:

• 2 months PITIA on the subject property
• Plus 2–6 months on each additional financed property (scaling with total count)

For a borrower with 4 financed rentals, that can mean $35K–$60K liquid in reserves on top of down payment and closing costs. Reserves can be in checking, savings, brokerage, or 60% of vested retirement.

DSCR lenders simplify: typically 6 months PITIA on the subject property only, regardless of other holdings.

Debt-to-Income (DTI) Rules

Conventional investment loans cap DTI at 45% (50% with strong compensating factors like 740+ FICO and 12+ months reserves). The rental income from the subject property contributes 75% of projected rent toward your qualifying income.

DSCR has no DTI calculation — the property’s rent simply has to cover the loan payment at the lender’s required ratio (1.0–1.20 typically).

Lender Type	Min DSCR	What “1.0” Means
Aggressive DSCR	0.75–1.00	Rent ≥ 75–100% of PITIA
Standard DSCR	1.00–1.20	Rent fully covers PITIA + cushion
Conservative DSCR	1.25+	25% cushion above PITIA
Portfolio bank	1.20–1.30	Bank-specific, often relationship-driven

Rate Premiums (Investment vs. Owner-Occupied)

In 2026:

Loan Type	Owner-Occ Rate	Investment Rate	Premium
Conventional 30-yr	6.85%	7.45%	+60 bps
FHA 30-yr	6.75%	N/A	—
VA 30-yr	6.50%	N/A	—
DSCR 30-yr	N/A	7.85%	+100 bps vs O/O conv
Portfolio	N/A	8.10%	+125 bps

Rate premiums also scale with LTV. 75% LTV on conventional adds another 25 bps versus 65% LTV. 80% LTV adds 50 bps.

Property Eligibility

Lenders are pickier about investment properties than primary residences. Common disqualifiers:

• Properties with unpermitted ADUs (some lenders OK, others not)
• Recently converted condos in litigation
• Properties with 5+ acres (treated as agricultural)
• Working farms or ranches
• Mixed-use over 25% commercial
• Manufactured homes (allowed only on certain DSCR programs)
• Co-ops (rarely financed as investments)

Documentation Checklist

For conventional investment:

• 2 years W-2s and tax returns
• 2 most recent paystubs
• 2 most recent bank statements (all accounts)
• Schedule E for any existing rentals
• Lease agreements on existing rentals
• Reserve documentation (brokerage, retirement)
• Property contract, appraisal, title commitment

For DSCR:

• ID and SSN
• Bank statement showing reserves
• Property contract
• Lease (if existing) or appraiser market rent
• Insurance binder
• LLC operating agreement (if titled in LLC)

DSCR underwriting is dramatically lighter — typical file size is 30–50 pages versus 200–400 for conventional.

Special Rules: First Investment vs. Second+

Fannie’s investment-property rules tighten as you accumulate financed properties:

• Properties 1-4: Standard 20–25% down, 6 months reserves
• Properties 5-6: 25% minimum down, 6 months reserves on each
• Properties 7-10: 30% down, 6 months reserves on each, additional documentation
• Beyond 10: Conventional unavailable. Move to DSCR or portfolio.

This is why most investors hit a wall around property 5–7 and switch to DSCR.

How to Get Approved Faster

1. Pull your credit 60 days before you apply. Dispute anything wrong; pay down revolving balances.
2. Document reserves clearly. Move money into one or two accounts, leave it for 60 days, screenshot statements.
3. Get pre-approved on two products. One conventional, one DSCR — let the deal pick the right loan.
4. Have your existing rental Schedule Es organized. Lenders want clean, readable returns with rental income shown.
5. Don’t open new credit during underwriting. Even an Amazon card application can drop your FICO 5–10 points.

FAQ — Investment Property Mortgages

Q: Can I get an investment loan with 10% down? A: Not on standard conventional or DSCR. House-hacking with FHA (3.5%) or VA (0%) is the only sub-15% path.

Q: Does the rental income help me qualify? A: Yes — on conventional, lenders count 75% of projected/actual rent toward qualifying income.

Q: Can I close in an LLC? A: Yes on DSCR (standard). Yes on conventional but title typically needs to be in your name personally; you can transfer to LLC after closing (carefully).

Q: How long do I need to be self-employed? A: 2 years for conventional. 0 years for DSCR — they don’t review income.

Q: Are rates negotiable? A: Yes. Get 2–3 quotes and use the lowest as leverage. Pricing varies 25–50 bps for identical borrowers.

Q: What if I can’t meet reserve requirements? A: Borrow against retirement (60% of 401(k) counts) or use a HELOC on your primary home. Don’t fake it — lenders verify all sources.

Final Verdict

Investment-property lending in 2026 is tighter than 2021 but more predictable than 2008. Hit 740+ FICO, document 6 months of reserves on every property, and stay under 45% DTI on conventional applications — that’s the formula for clean approvals. Once you cross 5 properties, plan your transition to DSCR before you hit Fannie’s 10-loan ceiling. The borrowers who scale fastest are the ones who treat documentation as a competitive advantage rather than a chore.
