How California Rent Control Laws Impact Property Appraisals

When you apply for a DSCR loan in California, the lender's primary concern is the property's ability to generate enough income to cover the mortgage payment. Rent control laws, like the statewide Tenant Protection Act (AB 1482) and stricter local ordinances in cities like Los Angeles and San Francisco, directly influence this calculation, which makes the appraisal process especially important.

An appraiser evaluating a rent-controlled property will provide two key values:

  1. As-Is Value: This reflects the property's worth with the current tenants and their below-market rents in place. It acknowledges the income is currently restricted.
  2. Market Value: This reflects the property's potential worth if it were vacant or leased to new tenants at the current market rate. This value is heavily influenced by the Form 1007, or Single-Family Comparable Rent Schedule, which analyzes what similar, non-rent-controlled units are renting for in the neighborhood.

Lenders heavily lean on the market value and the accompanying rent schedule. They understand that laws like the Costa-Hawkins Rental Housing Act allow landlords to raise the rent to market rates once a unit is voluntarily vacated. This 'vacancy decontrol' is the key that unlocks the property's true income potential, and it's what gives lenders the confidence to finance the deal.

Will My DSCR Loan Be Based on Current or Market Rents?

This is the most critical question for any investor buying a property with long-term, low-paying tenants. The good news is that most savvy DSCR lenders will base their calculations on potential market rents, not the artificially low in-place rents. (The data, information, or policy mentioned here may vary over time.)

The Debt Service Coverage Ratio (DSCR) formula is simple: Gross Rental Income / PITI (Principal, Interest, Taxes, Insurance). A ratio of 1.25x is a common benchmark, meaning the property's income must be at least 25% greater than its total housing expense. (The data, information, or policy mentioned here may vary over time.)

Here’s how using market rent makes a deal possible:

Scenario 1: Underwriting with Current Rent

Scenario 2: Underwriting with Market Rent

Comparing current rent vs market rent for DSCR loan approval

Lenders can use market rents because their risk model is based on the asset's long-term potential. They are betting that, over time, the property's income will rise to meet its market potential. However, this is only possible if you partner with a lender experienced in California investment properties.

Why Was My Loan Denied Due to a Rent-Controlled Tenant?

Even with the ability to use market rents, a DSCR loan for a rent-controlled property can still be denied. Lenders are not just looking at numbers; they are evaluating risk. A denial often comes down to specific risks associated with the tenant or the property that make achieving market rents seem too difficult or uncertain.

Common reasons for denial include: (The data, information, or policy mentioned here may vary over time.)

What Extra Documentation Will Underwriters Require?

Underwriting a rent-controlled property requires a higher level of scrutiny. Lenders need to verify every detail about the tenancy to feel secure. Be prepared to provide more than just a standard loan application.

Expect requests for the following documents: (The data, information, or policy mentioned here may vary over time.)

How to Find Lenders for California Rent-Controlled Properties

Finding the right lender is the difference between a quick approval and a frustrating denial. Large retail banks that primarily sell their loans to Fannie Mae and Freddie Mac often have rigid guidelines that automatically flag rent-controlled properties as too risky. You need to look elsewhere.

  1. Work with a Specialized Mortgage Broker: An independent mortgage broker who specializes in investment properties is your best asset. They have established relationships with dozens of lenders, including those with specific programs designed for rent-controlled buildings. They know which lenders use market rents and can navigate complex underwriting requirements.
  2. Target Portfolio Lenders: These are banks, credit unions, or private lenders that keep the loans they originate on their own books (in their 'portfolio'). Because they aren't selling the loan, they have the flexibility to set their own underwriting rules. They are more likely to use a common-sense approach to evaluating a deal.
  3. Ask Lenders Direct Questions: When you speak to a potential lender, be upfront. Ask them directly: 'How do you underwrite multi-family properties with tenants protected by local rent control ordinances?' Their answer will tell you everything you need to know about their experience and flexibility.

Can Income from an ADU Help My DSCR Loan Get Approved?

Absolutely. The surge in Accessory Dwelling Unit (ADU) construction in California has created a powerful tool for real estate investors. Adding a legal, permitted ADU can significantly improve your DSCR calculation and make an otherwise unworkable deal get approved.

Because a newly constructed ADU has no rental history, it is not subject to rent control limitations at the outset. Its income is based purely on the current market rate. (The data, information, or policy mentioned here may vary over time.)

Consider this example:

Without the ADU, the lender would use the $4,000 market rent for the main house, resulting in a DSCR of 0.78x ($4,000 / $5,100), leading to a denial. But with the ADU, the calculation changes.

This new ratio is much closer to the lender's 1.25x target and could be approved, possibly with a slightly larger down payment. For the lender to consider ADU income, you must provide proof that the unit is fully permitted and has received its certificate of occupancy.

What Are the Biggest Underwriting Risks Lenders See?

Understanding a lender's fears helps you prepare your loan file to address them proactively. For California rent-controlled properties, the risks all center around the time and uncertainty involved in reaching the property's market potential.
