Mortgage Insurance on Investment
Mortgage Insurance on Investment
Investment property mortgages don't carry PMI (private mortgage insurance). Owner-occupied mortgages allow 3–5% down because PMI protects the lender; investment properties require 25%+ down because lenders won't insure them.
Key takeaways
- PMI exists for owner-occupied mortgages, allowing 5–10% down; PMI doesn't exist for investment property, requiring 25%+ down
- The lender's loss severity on investment property is higher (lower occupancy risk, tenant payment risk) and the borrower's commitment is lower (they live elsewhere), making insurance uneconomical
- 25% down is effectively a non-negotiable minimum on residential investment property; some commercial lenders go lower (20% LTV) on stabilized assets, but below 25% is rare
- This down payment constraint is the single largest barrier to entry for individual investors and directly shapes portfolio-building strategies
- Leverage-seeking investors can access lower-down options (DSCR loans, portfolio lenders) but at higher rates and stricter DSCR requirements
Why PMI Doesn't Exist for Investment Property
PMI (private mortgage insurance) protects the lender if you default. On a 10% down owner-occupied mortgage, PMI covers the lender's loss if the home is foreclosed and sells for less than the loan balance. PMI exists because:
- Owner-occupant commitment: You live in the house. Foreclosure is personally traumatic. You'll work hard to avoid it.
- Lower default rate: Owner-occupied mortgages default at 0.2–0.5%/year; investment property defaults at 1–2%/year.
- Predictable value: Home values are well-documented (comps, neighborhood data). Risk is quantifiable.
- Insurance business model: PMI companies can pool risk across millions of similar mortgages and price accordingly.
On an investment property, these don't hold:
- Lower commitment: You don't live in the property. Foreclosure is a financial loss, not a personal catastrophe. Default is more tempting.
- Higher default rate: As noted above, 1–2%/year vs. 0.2–0.5%.
- Operational risk: Investment property value depends on tenant quality, lease terms, occupancy, capital expenditures. This is harder to underwrite and predict than home values.
- Adverse selection: Investors buying with low down (10% down) are likely stretched or speculative. Those with capital prefer not to be stretched (they buy at 30–40% down).
PMI companies, facing 5–10x higher default rates and unpredictable loss severity, simply don't offer investment property insurance. The business doesn't work.
25% Down: The de facto floor
Most lenders require 25% down on investment property:
| Property Type | Min Down | LTV Ceiling |
|---|---|---|
| Primary residence (conventional) | 3–5% | 95–97% LTV |
| Primary residence (FHA) | 3.5% | 96.5% LTV |
| 2–4 unit investment (conventional) | 25% | 75% LTV |
| Apartment 5+ units (commercial) | 25–30% | 70–75% LTV |
| Commercial office/retail | 25–35% | 65–75% LTV |
The 25% ceiling is hard. Fannie Mae, the largest mortgage aggregator, caps investment property mortgages at 75% LTV. Portfolio lenders, which have more flexibility, still rarely go below 70% LTV (30% down) on residential investment property.
This creates a capital barrier: you must bring $250,000 in cash to acquire a $1,000,000 property. For comparison, an owner-occupant can buy the same property with $50,000 down (5%).
Capital Requirements: Owner-Occupant vs. Investor
Purchasing a $1M property:
| Scenario | Down % | Down $ | Loan | LTV |
|---|---|---|---|---|
| Owner-occupant | 5% | $50k | $950k | 95% LTV |
| Investment, conventional | 25% | $250k | $750k | 75% LTV |
| Investment, portfolio lender | 20% | $200k | $800k | 80% LTV |
An owner-occupant and investor purchasing the same property have vastly different capital requirements. The owner-occupant needs $50k; the investor needs $200–250k. The investor is immediately at a disadvantage in terms of leverage.
Exceptions: Lower Down on Investment Property
Some lenders do offer lower down (20% on investment residential, 20–25% on commercial):
Portfolio lenders specializing in investment property: Banks holding their own mortgages, with deep expertise in investment property underwriting, sometimes accept 20% down (80% LTV) if:
- Property is stabilized and rent-stabilized (90%+ occupancy, market-rate rent)
- DSCR is strong (1.25x+)
- Borrower has significant experience (5+ properties) or strong balance sheet
DSCR-specific lenders: Some DSCR lenders accept 20% down (80% LTV) on residential investment because they underwrite to the property's cash flow (DSCR), not the borrower's credit. They're comfortable with leverage if the property covers its own debt service.
Commercial lenders on larger deals: A $2M apartment building (5+ units) might be financed at 75% LTV (25% down) by a bank, or 80% LTV (20% down) by a more aggressive portfolio lender.
Hard money lenders: Hard money lenders base LTV on after-repair value and don't require cash down the same way. A hard money fix-and-flip might finance 65–75% ARV, but the borrower brings acquisition and rehab capital upfront. LTV is lower, but down payment requirement is often negotiable.
All of these require trade-offs: higher rates, stricter DSCR, or shorter loan terms.
DSCR Loans as a Down Payment Workaround
DSCR-specific loans offer a partial path around the 25% down requirement:
A property with strong NOI might qualify for an 80% LTV DSCR loan, bringing down payment to 20%. But the rate is 150–250 bps higher:
| Loan Type | LTV | Down | Rate | Payment | DSCR Required |
|---|---|---|---|---|---|
| Conventional portfolio | 75% LTV | 25% | 6.75% | 6,866/mo (on $750k) | 1.25x |
| DSCR (80% LTV) | 80% LTV | 20% | 8.25% | 8,130/mo (on $800k) | 1.0x |
On a $1M property with $180k NOI:
- Conventional: 1.25x DSCR required; max $144k debt service
- DSCR: 1.0x DSCR required; max $180k debt service
The DSCR lender allows higher leverage and lower down because they underwrite on cash flow. But the trade-off is clear: 150 bps higher in rate.
Down Payment Strategies for Investors
Experienced investors navigate the 25% down floor using several strategies:
Stacking leverage across properties: You own Property A with 25% equity (75% LTV). You buy Property B with 25% down (75% LTV). Then you buy Property A with cash from a HELOC or hard money bridge, pull equity out as a cash-out refi, and use that cash for Property C's down payment. This requires a portfolio of property and credit to execute, but it allows an investor to deploy capital more aggressively.
Partnering or syndication: Instead of bringing 25% down on a $1M property ($250k), you bring 12.5% and partner with another investor. The partnership brings 12.5% ($125k). You collectively own the property with 25% down and finance 75%. Each partner controls a 50% stake.
Owner financing from the seller: In some deals, the seller will carry back a second mortgage (owner financing). You might bring 10% cash ($100k), get a first mortgage for 70% ($700k), and the seller carries back 20% ($200k) as a second mortgage. This effectively drops your cash requirement to 10%, though it's rare and requires a flexible seller.
Affiliate financing or joint ventures: A lending partner or sponsor with deeper capital might provide down payment financing (hard money or mezzanine debt) that you repay from cash flow. This is common in larger syndications.
Portfolio loans with flexible LTV: A portfolio lender who knows you and your track record might offer 80% LTV (20% down) as a relationship benefit. You've done 5 deals with them, all performing; they'll finance the 6th at lower equity requirement.
Impact on Portfolio Growth
The 25% down requirement directly constrains portfolio growth:
Scenario A (owner-occupant buying primary residence):
- Capital: $100k saved
- Property purchase: $2M at 5% down ($100k)
- Loan: $1.9M
- Leverage: 95% LTV (max)
Scenario B (investor building rental portfolio):
- Capital: $100k saved
- Property purchase: $400k at 25% down
- Loan: $300k
- Leverage: 75% LTV (max)
The owner-occupant can deploy $100k to acquire $2M in real estate. The investor can deploy $100k to acquire $400k in real estate. The owner-occupant gets 20x leverage; the investor gets 4x leverage.
This 5x difference in leverage is the primary reason investment real estate portfolio growth is slower than primary-residence accumulation for same-size groups. It's also why investor syndication, partnerships, and funds exist—they aggregate capital to meet the down payment requirements and achieve economies of scale.
Historical PMI on Investment: Why It Failed
In the 2000s, some mortgage insurers offered "non-owner-occupied mortgage insurance" (PMI for investment property). The business failed spectacularly. During the 2007–2012 financial crisis, investment property default rates hit 10–20%+ (vs. 3–5% for owner-occupied). PMI claims exhausted reserves, and most insurers exited the market or collapsed.
This historical failure reinforced the lender consensus: investment property can't be insured economically. The only way to protect against loss is to require enough equity (25%+) that the lender has a cushion.
Modern lenders have internalized this: the down payment is the insurance. 25% down ensures the lender can foreclose, sell the property in a down market (liquidate at 80–90% of fair value), and still recover.
