## Definition

**Loan-to-value ratio** (LTV) measures the size of your mortgage as a percentage of the property's appraised value. It is one of the primary risk metrics lenders use when underwriting real estate loans.

$$\text{LTV} = \frac{\text{Loan Amount}}{\text{Property Value}} \times 100$$

A lower LTV means more equity — a safer position for the lender and lower risk premiums for you.

## How to Calculate LTV

**Formula:**

$$\text{LTV} = \frac{\text{Loan Amount}}{\text{Property Value}} \times 100$$

**Worked example:**

- Purchase price: $450,000
- Down payment: 20% = $90,000
- Loan amount: $450,000 − $90,000 = **$360,000**
- **LTV: $360,000 ÷ $450,000 × 100 = 80%**

You can also calculate the maximum loan amount from a target LTV:

$$\text{Max Loan} = \text{Property Value} \times \text{LTV\%}$$

For an 80% LTV cap on a $450,000 property: $450,000 × 0.80 = **$360,000 max loan**.

## Why Lenders Care About LTV for STR Loans

LTV represents the lender's risk exposure. If you default and the lender must foreclose, a lower LTV means more cushion between the outstanding loan balance and the property's sale price.

STR properties carry additional risk in lenders' eyes compared to primary residences or long-term rentals:

- **Income volatility**: STR revenue fluctuates with seasons, platform policy changes, and local competition.
- **Operational risk**: STR properties require active management; mismanaged properties see sharper value and revenue declines.
- **Regulatory risk**: Short-term rental regulations can change and limit a property's income potential.

Because of this elevated risk profile, STR lenders often require **lower LTV (higher down payment)** than they would for a comparable long-term rental property.

## LTV Thresholds by Loan Type

| Loan Type | Typical Max LTV | Notes |
|-----------|----------------|-------|
| Conventional (Fannie/Freddie) | 75–80% | Stricter for investment properties; primary residence rules don't apply |
| DSCR loan | 75–80% | Some lenders go to 85% with stronger credit and reserves |
| Portfolio / bank loan | 65–75% | Community banks and credit unions often want more equity |
| Hard money / bridge | 60–70% | Short-term; higher rate in exchange for speed and flexibility |

Most STR investors finance with DSCR loans, where the **80% LTV (20% down)** threshold is the common ceiling. Going below 75% LTV often unlocks better pricing.

## Higher LTV = Higher Rate

Lenders price risk into your interest rate. The relationship is not linear, but crossing certain LTV thresholds triggers meaningful rate adjustments:

| LTV | Rate Impact (Approximate) |
|-----|--------------------------|
| ≤ 60% | Best available rate |
| 61–70% | Small premium (+0.125–0.25%) |
| 71–75% | Moderate premium (+0.25–0.375%) |
| 76–80% | Standard premium (+0.375–0.5%) |
| > 80% | Significant premium + possible PMI or structural changes |

These are approximate loan-level price adjustments (LLPAs) — actual pricing varies by lender, credit score, loan size, and property type. The key takeaway: **every point of LTV above 75% costs you in rate**, which directly reduces cash flow and [cash-on-cash-return](/learn/cash-on-cash-return).

## LTV and PMI

On conventional loans, LTV above 80% typically triggers **private mortgage insurance (PMI)** — an additional monthly premium that compensates the lender for the higher risk. PMI is rare on investment properties (most lenders require 20% down as a condition of lending), but on owner-occupied STR properties (househacking or vacation homes you use personally), it can apply.

PMI cost: typically 0.5–1.5% of the loan amount annually. On a $360,000 loan, that's $1,800–$5,400/year — a real drag on returns.

## LTV and DSCR Interact

LTV and [what-is-dscr](/learn/what-is-dscr) are closely linked. A higher LTV means:

1. Larger loan balance
2. Higher monthly P&I payment
3. Higher annual debt service
4. Lower DSCR at the same income level

**Example — same $450K property, different LTV:**

| LTV | Loan Amount | Monthly P&I (7.25%, 30yr) | Annual Debt Service | DSCR (at $35K NOI) |
|-----|-------------|--------------------------|--------------------|--------------------|
| 70% | $315,000 | $2,149 | $25,788 | 1.36x |
| 75% | $337,500 | $2,302 | $27,624 | 1.27x |
| 80% | $360,000 | $2,456 | $29,472 | 1.19x |

Dropping from 80% to 70% LTV improves DSCR from 1.19x to 1.36x on the same property — the difference between a tight deal and a comfortable one for most lenders.

## How to Lower Your LTV

**Put more down.** The most direct lever. A larger down payment reduces your loan balance and LTV immediately. The tradeoff is lower [cash-on-cash-return](/learn/cash-on-cash-return) if the additional cash could otherwise be deployed in another deal.

**Buy below appraised value.** If you negotiate a purchase price below the appraised value, your LTV is calculated on the appraised value — giving you instant equity. Not always possible, but worth pursuing in motivated-seller situations.

**Refinance after appreciation.** As the property appreciates, your LTV drops. A refinance at a lower LTV can improve your rate and eliminate PMI, improving ongoing cash flow.

## Common Mistakes

**Confusing purchase price with appraised value.** LTV uses the appraised value, not what you paid. If you overpay for a property and the appraisal comes in low, your effective LTV is higher than you planned.

**Ignoring LTV's effect on [break-even-occupancy](/learn/break-even-occupancy).** Higher LTV means higher debt service, which raises the occupancy rate you need to cover costs. A deal that breaks even at 55% occupancy at 70% LTV might require 65% occupancy at 80% LTV.

**Treating 20% down as automatic approval.** LTV is necessary but not sufficient. STR lenders also evaluate DSCR, credit score, cash reserves, and property type. 80% LTV with a DSCR of 0.9x is still a declined loan.
