How to Refinance an Investment Property in 2026

Refinancing a rental property is different than refinancing your primary residence. Higher rates. Stricter requirements. But still worth it if you do it right.

I've helped investors refinance dozens of rental properties in California. Here's what you need to know.

Investment Property vs Primary Residence

Primary residence refinance:

• Rates: 6.00-6.50%
• Max LTV: 97%
• DTI: Up to 50%
• Reserves: 2 months minimum

Investment property refinance:

• Rates: 6.50-7.50% (0.5-1% higher)
• Max LTV: 75% (need 25% equity)
• DTI: Up to 45% (stricter)
• Reserves: 6 months minimum (sometimes 12 months)

Why the difference? Lenders see investment properties as higher risk. If you lose your job, you'll prioritize your primary residence over your rental.

Broker's Tip: If you live in one unit of a 2-4 unit property, it qualifies as owner-occupied (primary residence rates apply). This is a huge savings opportunity for house hackers.

Investment Property Refinance Requirements

1. Minimum Equity: 25%

You need 25% equity to refinance an investment property.

Example:

• Property value: $500,000
• Max loan: $500,000 × 75% = $375,000
• Current mortgage: $400,000
• You can't refinance (not enough equity)

Wait for appreciation or pay down principal to hit 25% equity.

2. Cash Reserves: 6-12 Months

Lenders require 6-12 months of mortgage payments in liquid reserves (checking, savings, stocks — not retirement accounts unless you can access them penalty-free).

Example calculation:

• New mortgage payment (PITI): $2,800
• Required reserves: $2,800 × 6 = $16,800 minimum in the bank

If you have multiple investment properties, lenders add up ALL your rental property payments and require reserves for all of them.

3. Credit Score: 680+ (Higher Is Better)

Minimum: 620 (most lenders) Best rates: 740+

Below 680, expect rate hits of 0.5-1%.

4. Debt-to-Income: 45% Max

DTI = Total Monthly Debt ÷ Gross Monthly Income

Important: Lenders count your rental property's mortgage payment in your debt (even if you have a tenant paying rent).

How rental income affects DTI:

• If you have a 2-year history of rental income (tax returns showing Schedule E), lenders count 75% of the rent as income
• If you don't have 2-year history, rental income doesn't count

Example:

• Gross monthly income (W-2): $10,000
• Rental income (75% of $2,500 rent): $1,875
• Total income: $11,875
• Personal residence mortgage: $2,500
• Rental property mortgage: $2,200
• Car payment: $400
• Total debt: $5,100
• DTI: 43% ($5,100 ÷ $11,875)

You qualify (under 45%).

Broker's Tip: If you're close to the DTI limit, pay off a car or credit card before applying. Lowering DTI by 2-3% can make or break your approval.

Investment Property Rates (March 2026)

Rate tiers by credit score:

| Credit Score | 30-Year Fixed Rate | 15-Year Fixed Rate | |--------------|--------------------|--------------------| | 760+ | 6.50-6.75% | 5.875-6.125% | | 740-759 | 6.75-7.00% | 6.125-6.375% | | 720-739 | 7.00-7.25% | 6.375-6.625% | | 700-719 | 7.25-7.50% | 6.625-6.875% | | 680-699 | 7.50-7.875% | 6.875-7.125% |

Add 0.25-0.50% for:

• Cash-out refinance
• LTV above 70%
• 2-4 unit properties

Cash-Out Refinance for Investment Properties

Max cash-out LTV: 75% (some lenders allow 70% only)

Example:

• Property value: $600,000
• Max loan at 75% LTV: $450,000
• Current mortgage: $350,000
• Max cash-out: $100,000

Common uses:

• Down payment on another rental property
• Renovations to increase rent
• Pay off high-interest debt
• Build cash reserves

Rates on cash-out: Add 0.375-0.625% to standard investment property rates.

See our cash-out refinance guide.

DSCR Loans: No Income Verification

DSCR (Debt Service Coverage Ratio) loans qualify you based on the property's rental income, not your personal income.

How it works:

• Lender orders a rent appraisal (what market rent is for your property)
• They calculate DSCR: Monthly Rent ÷ Monthly Mortgage Payment
• DSCR of 1.0+ = you qualify (rent covers the mortgage)

Example:

• Market rent: $3,000/month
• New mortgage payment (PITI): $2,700
• DSCR: 1.11 (rent is 111% of payment)
• You qualify (even if your personal income is low)

DSCR loan rates: Usually 0.5-1% higher than standard investment property rates (7.0-8.0% range).

When to use DSCR loans:

• Self-employed with complicated tax returns
• High income but lots of write-offs (low taxable income)
• Retired with minimal W-2 income

Broker's Tip: DSCR loans are more expensive but easier to qualify for. If you can qualify for a traditional investment property loan, do that — save 0.5-1% on your rate.

Streamline Refinance for Investment Properties

Can you do a streamline refinance on an investment property?

FHA: No (FHA requires owner-occupancy) VA: No (VA requires owner-occupancy or prior occupancy) Conventional: No streamline option exists

You're stuck with full documentation refinance (income verification, appraisal, reserves, full underwriting).

Tax Benefits of Investment Property Refinance

1. Interest Is Tax-Deductible

All mortgage interest on investment properties is deductible (Schedule E on your tax return).

Example:

• Annual interest paid: $25,000
• Tax bracket: 32%
• Tax savings: $8,000/year

2. Closing Costs Are Deductible (Over Time)

Refinance closing costs are amortized over the life of the loan (not deducted in year 1).

Example:

• Closing costs: $6,000
• Loan term: 30 years
• Annual deduction: $200/year

Multi-Unit Properties (2-4 Units)

2-4 unit properties have different rules:

Owner-occupied (you live in one unit):

• Treated as primary residence
• Rates: Same as single-family primary residence
• Max LTV: 85-90%

Non-owner-occupied (pure investment):

• Treated as investment property
• Rates: Investment property rates
• Max LTV: 75%
• Higher reserves required (6-12 months)

Broker's Tip: If you're buying a duplex, triplex, or fourplex and you can live in one unit for 12 months, you save THOUSANDS by qualifying as owner-occupied. After 12 months, you can move out and keep the low rate.

Should You Refinance Your Rental Property?

Refinance if:

1. You can drop your rate by 1%+. On a $400,000 loan, 1% = $240/month savings ($2,880/year).

2. You need cash to buy another property. Cash-out refinance at 7% is cheaper than hard money at 10-12%.

3. You're switching from an ARM to fixed. Lock in today's rates before your ARM adjusts higher.

4. Your rental income increased and you can count it now. If you didn't have 2 years of rental income when you bought, you might qualify for better terms now.

Don't refinance if:

1. Break-even is over 5 years. Investment property loans have higher closing costs ($6,000-$10,000). Make sure you'll recover them.

2. You're selling soon. Don't pay $8,000 in closing costs if you're offloading the property in 18 months.

3. Your rate increase is minimal. Going from 6.5% to 6.75% to take cash out? Might not be worth it.

Frequently Asked Questions

Q: Can I refinance a short-term rental (Airbnb)?

Yes, but lenders treat it as an investment property. Some lenders won't count Airbnb income (too variable). Expect stricter underwriting.

Q: What if my rental property is vacant?

Lenders will still approve you, but they won't count rental income (DTI will be higher). Some require proof the property is listed for rent.

Q: Can I refinance multiple rental properties at once?

Yes, but each property is a separate loan. You'll need reserves for all of them (adds up fast).

Q: Do I need an appraisal?

Yes. Investment property refinances always require an appraisal (no streamline/no-appraisal option exists).

Q: Can I use rental income from the property I'm refinancing?

Yes, if you have 2 years of tax returns showing Schedule E rental income. Lenders count 75% of the rent as qualifying income.
