Investment Property vs. Primary Residence Refinance: Key Differences
| Requirement | Investment Property | Primary Residence |
|---|---|---|
| Minimum equity (LTV) | 20–25% (75–80% max LTV) | 3–5% (95–97% max LTV) |
| Cash-out max LTV | 75% (single family) | 80% |
| Credit score (minimum) | 680 | 620 |
| Credit score (best pricing) | 740+ | 740+ |
| Cash reserves required | 6+ months PITI (per property) | 2 months typical |
| Rate premium | 0.5–0.75% above primary residence | Baseline rate |
| FHA / VA / USDA available? | No | Yes |
| Rental income qualifying | 75% of gross rent counts | N/A |
| DTI limit | Typically 45% | Up to 50–57% with factors |
| Appraisal | Full appraisal + rent schedule (Form 1007) | Full appraisal |
Investment Property Rate Premiums (LLPAs)
Fannie Mae and Freddie Mac charge Loan Level Price Adjustments (LLPAs) for investment properties. These translate to higher rates — effectively a surcharge for the added default risk of non-owner-occupied properties. See Fannie Mae's LLPA matrix for current pricing.
| Credit Score | LTV 60–65% | LTV 65–70% | LTV 70–75% |
|---|---|---|---|
| 740+ | ~0.50% rate premium | ~0.625% rate premium | ~0.75% rate premium |
| 720–739 | ~0.75% | ~0.875% | ~1.00% |
| 700–719 | ~1.00% | ~1.125% | ~1.25% |
| 680–699 | ~1.25% | ~1.375% | ~1.50% |
At a 740+ score and 70% LTV, a $350,000 investment property loan at 0.75% premium above a primary residence rate of 7.00% costs 7.75% — approximately $137/month more ($1,644/year) on that balance. Over 30 years: approximately $49,000 in additional interest compared to a primary residence rate. Use the APR Calculator to compare investment property loan offers.
Using Rental Income to Qualify
Rental income from the subject property can count toward your qualifying income — reducing your debt-to-income ratio. Lenders apply a 25% vacancy and expense factor, counting 75% of gross rent:
- Gross monthly rent: $2,500/month
- Qualifying rental income: $2,500 × 75% = $1,875/month
- This $1,875 offsets the mortgage payment in DTI calculation, or can be added to income
Documentation required:
- Current signed lease agreement (if property is rented)
- Form 1007 (Single Family Comparable Rent Schedule) if property is vacant
- Schedule E from last 2 years of tax returns (if you have owned 2+ years)
- 2 months of bank statements showing rent deposits
Cash Reserves: The Most Often-Missed Requirement
Investment property refinances require significant cash reserves — not just for the subject property, but for every financed property you own:
- Subject property: 6 months of PITI (principal, interest, taxes, insurance)
- Each additional financed property (primary + any other rentals): 2–6 months of PITI each, depending on lender and number of properties
- Total: Can easily require $50,000–$100,000+ in liquid reserves for investors with multiple properties
Acceptable reserves: checking, savings, money market accounts (100%), vested 401(k)/IRA (60–70% after penalty), stocks and bonds (100% of current value). Non-acceptable: equity in real estate, anticipated income, gifts.
DSCR Loans: An Alternative for Investment Property Refinances
If your personal income doesn't support DTI requirements, Debt Service Coverage Ratio (DSCR) loans qualify based on the property's rental income alone — no personal income verification required:
| Feature | DSCR Loan | Conventional Investment |
|---|---|---|
| Qualification basis | Property rental income vs. PITI | Borrower personal income + DTI |
| Income docs required | None (sometimes) | Tax returns, W-2s, pay stubs |
| Minimum DSCR | Typically 1.0–1.25 (rent ≥ mortgage payment) | N/A |
| Max LTV | 75–80% | 75–80% |
| Rate premium | 0.5–1.5% above conventional | 0.5–0.75% above primary |
| Credit score minimum | 680–700+ | 680 |
DSCR = Monthly Gross Rent ÷ Monthly PITI. A DSCR of 1.25 means the property earns 25% more than the mortgage costs. Most DSCR lenders require 1.0 minimum (breakeven) to 1.25 (preferred). Properties with DSCR below 1.0 (negative cash flow) may not qualify for DSCR loans.
LLC vs. Personal Name: Refinancing Considerations
Many real estate investors hold investment properties in LLCs for liability protection. This adds complexity to refinancing:
- Conventional (Fannie/Freddie) loans cannot be made to LLCs — the loan must be in a personal name. If the property is held in an LLC, you may need to deed it out of the LLC, refinance personally, then deed it back — consult a real estate attorney as this may trigger a due-on-sale clause review.
- Commercial or portfolio loans can be made to LLCs but at commercial rates (typically higher than residential conventional rates) and with personal guarantees required.
- DSCR loans can often be made to LLCs, making them the most LLC-friendly refinance option for investors who want liability protection.

2-4 Unit Properties: Stricter Requirements
Multi-unit investment properties (2–4 units) face tighter LTV limits than single-family rentals. The same conventional guidelines apply — but with reduced LTV ceilings:
| Property Type | Max LTV (Rate/Term) | Max LTV (Cash-Out) | Min Reserves |
|---|---|---|---|
| Single-family investment | 75% | 75% | 6 months PITI |
| 2-unit investment | 70% | 70% | 6 months PITI |
| 3–4 unit investment | 70% | 70% | 6 months PITI |
| 5+ units (commercial) | Commercial loans only — not Fannie/Freddie | N/A | Lender-specific |
Properties with 5+ units leave conventional residential lending and require commercial mortgages — different rates, different underwriting, and different terms. If you are refinancing a small apartment building, confirm whether it is 4 units or fewer before assuming Fannie/Freddie guidelines apply. Use the LTV Calculator to check your equity position before deciding whether a multi-unit refinance is feasible at the 70% LTV cap.
For multi-unit properties with rental income, lenders use 75% of gross rents from the occupied units toward qualifying income — the same 75% rule as single-family. If the property has a vacant unit, the Form 1007 market rent schedule applies for that unit. Calculate the rent income impact with the Mortgage Savings Calculator after adjusting your qualifying income figure.
Pulling Out Equity for the Next Acquisition
One of the most common investment property refinance strategies is cash-out refinancing to fund additional property purchases — sometimes called the BRRRR strategy (Buy, Rehab, Rent, Refinance, Repeat):
- Equity available for cash-out: Property value × 75% − current loan balance = maximum cash you can pull. Example: $600,000 property, $300,000 loan → $600K × 75% = $450K − $300K = $150,000 available cash-out. Use the Cash-Out Calculator to model your specific scenario.
- Tax note: Cash-out proceeds are not immediately taxable income. However, interest on the increased loan amount is only deductible against the investment property — not against personal income unless passive income exists. See IRS Publication 936 for mortgage interest deduction rules on investment properties.
- Cash flow impact: Cash-out increases your mortgage balance and monthly payment. Verify the property still cash-flows positively at the new payment. Use the Refinance Payment Calculator to confirm the new PITI, then subtract it from your rental income to calculate post-refinance cash flow.
- Reserve requirement after cash-out: After closing, you still need 6 months of PITI in liquid reserves. The cash you pulled out cannot be used to satisfy this requirement — you need the reserves independent of the cash-out proceeds.
Compare the cost of a cash-out refinance against alternatives using the cash-out vs. HELOC guide — sometimes a HELOC is cheaper than refinancing the entire balance at a higher rate.
When to Refinance vs. When to Sell
Not every investment property should be refinanced. A quick framework:
- Refinance if: Current rate is 0.5%+ above market, you'll hold 3+ more years, positive cash flow is maintained at the new payment, and LTV is below 75%. Use the Break-Even Calculator to confirm the closing costs recoup within your hold period.
- Sell if: Cap rate on the property is below 4–5% (you could deploy equity into higher-yield properties), the refinance still leaves the property cash-flow negative, or you're within 3 years of selling anyway.
- Hold without refinancing if: The remaining loan balance is small (savings in dollar terms are minimal despite a decent rate drop), or you're within 5 years of payoff and restarting amortization would cost more in interest than it saves.
