Learn how to refinance rental properties and investment homes. Rates, requirements, and strategies from a CA mortgage broker.
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.
Primary residence refinance:
Investment property refinance:
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.
You need 25% equity to refinance an investment property.
Example:
Wait for appreciation or pay down principal to hit 25% equity.
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:
If you have multiple investment properties, lenders add up ALL your rental property payments and require reserves for all of them.
Minimum: 620 (most lenders) Best rates: 740+
Below 680, expect rate hits of 0.5-1%.
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:
Example:
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.
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:
Max cash-out LTV: 75% (some lenders allow 70% only)
Example:
Common uses:
Rates on cash-out: Add 0.375-0.625% to standard investment property rates.
See our cash-out refinance guide.
DSCR (Debt Service Coverage Ratio) loans qualify you based on the property's rental income, not your personal income.
How it works:
Example:
DSCR loan rates: Usually 0.5-1% higher than standard investment property rates (7.0-8.0% range).
When to use DSCR loans:
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.
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).
1. Interest Is Tax-Deductible
All mortgage interest on investment properties is deductible (Schedule E on your tax return).
Example:
2. Closing Costs Are Deductible (Over Time)
Refinance closing costs are amortized over the life of the loan (not deducted in year 1).
Example:
Consult your CPA. I'm a mortgage broker, not a tax advisor.
2-4 unit properties have different rules:
Owner-occupied (you live in one unit):
Non-owner-occupied (pure investment):
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.
Refinance if:
You can drop your rate by 1%+. On a $400,000 loan, 1% = $240/month savings ($2,880/year).
You need cash to buy another property. Cash-out refinance at 7% is cheaper than hard money at 10-12%.
You're switching from an ARM to fixed. Lock in today's rates before your ARM adjusts higher.
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:
Break-even is over 5 years. Investment property loans have higher closing costs ($6,000-$10,000). Make sure you'll recover them.
You're selling soon. Don't pay $8,000 in closing costs if you're offloading the property in 18 months.
Your rate increase is minimal. Going from 6.5% to 6.75% to take cash out? Might not be worth it.
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.
