One of the first questions every buyer asks is simple but loaded: how much house can I actually afford? In a market like Los Angeles, where prices run well above the national average and the gap between what you can qualify for and what is comfortable to own can be significant, getting this number right is the difference between a smooth purchase and a financially stressful one. Here is how lenders and smart buyers think about affordability in 2026.
The 28/36 rule: where to start
Most conventional mortgage lenders use the 28/36 rule as their baseline affordability benchmark. It says your monthly housing payment (principal, interest, property taxes, and insurance, or PITI) should not exceed 28 percent of your gross monthly income, and your total monthly debt payments (housing plus car loans, student loans, credit card minimums, and any other recurring obligations) should not exceed 36 percent.
For example, if your household earns $12,000 per month gross, your target housing payment is $3,360 (28 percent) and your total debt payments should stay below $4,320 (36 percent). If you have $800 per month in existing debt payments, your housing budget drops to $3,520 before you hit the 36 percent ceiling. Modern lenders often approve up to 43 to 45 percent total debt-to-income ratio, particularly for strong borrowers with reserves, but staying closer to 36 percent leaves a more comfortable financial cushion.
The real cost of ownership in Los Angeles
Sticker price is only part of the story. In Los Angeles County, property taxes run approximately 1.1 to 1.25 percent of the assessed purchase price per year. On an $800,000 home, that is $8,800 to $10,000 per year, or $730 to $830 per month added to your payment. Homeowners insurance for a single-family home in Los Angeles typically runs $1,500 to $3,000 per year depending on location, size, and fire risk zone, or $125 to $250 per month. If you buy a condo or a home in a community with a homeowners association, add HOA dues, which can range from $200 to over $1,000 per month depending on the development.
If your down payment is below 20 percent, add private mortgage insurance (PMI) for a conventional loan, typically 0.5 to 1.5 percent of the loan amount per year, or mortgage insurance premiums for an FHA loan. On a $640,000 loan with 0.75 percent PMI, that is $400 per month in addition to your principal and interest. All of these costs add up to a monthly payment that is significantly higher than the simple mortgage calculation most online calculators show.
How much down payment do you need?
You do not always need 20 percent down. Conventional loans allow as little as 3 percent down for first-time buyers (5 percent for repeat buyers). FHA loans require 3.5 percent down with a credit score of 580 or above. VA loans (available to eligible veterans and active duty military) require zero down payment and no mortgage insurance. USDA loans offer zero down for qualifying rural properties. Jumbo loans, which are needed for purchases above the conforming loan limit ($806,500 in Los Angeles County for 2026), typically require 10 to 20 percent down depending on the lender.
Putting less than 20 percent down means paying PMI, which adds to your monthly cost. However, putting too much down can deplete your reserves, which lenders also evaluate. Most financial advisors recommend keeping at least 2 to 3 months of mortgage payments in savings after closing. A 10 percent down payment with solid reserves is often preferable to 20 percent down with nothing left.
Down payment and closing cost programs in California
California first-time buyers have access to several assistance programs that can meaningfully reduce the cash needed at closing. CalHFA's MyHome Assistance Program provides a deferred junior loan of up to 3.5 percent of the purchase price to help with down payment and closing costs. The Dream For All program (when available) provides a shared appreciation loan of up to 20 percent of the purchase price in exchange for sharing a percentage of future appreciation when the home is sold. Los Angeles city and county also have local programs with their own eligibility requirements and funding cycles.
These programs have income limits, purchase price caps, and other eligibility requirements that vary by program and county. Our team works with lenders who specialize in first-time buyer programs and can identify exactly which options you qualify for based on your income, credit, and target location.
What do mortgage payments look like in Los Angeles?
At current rates, a 30-year fixed-rate mortgage on a $640,000 loan (an $800,000 home with 20 percent down) carries a principal and interest payment of approximately $4,100 to $4,400 per month depending on the rate. Add property taxes ($800 per month), insurance ($175 per month), and HOA (if applicable), and the all-in monthly housing cost for an $800,000 home runs $5,000 to $6,000 per month before PMI. To comfortably afford this with a 28 percent housing ratio, a household needs a gross income of approximately $18,000 to $21,000 per month, or $216,000 to $252,000 per year.
That income requirement highlights why dual-income households dominate the Los Angeles buyer market and why move-up buyers who have built equity in an existing home have a meaningful advantage. It also underscores why getting a precise, personalized number from a pre-approval matters far more than general guidelines.
Get pre-approved to know your real number
The fastest and most accurate way to determine what you can afford is a mortgage pre-approval. Your lender will review your actual income, credit, and assets and commit to a specific loan amount. This eliminates guesswork and gives you a real budget to shop with. In a competitive market like Los Angeles, a pre-approval is also a practical necessity: sellers and listing agents routinely require one before showing a home or considering an offer.
Our team works with trusted local lenders who can issue pre-approvals quickly, often within 24 hours of receiving your documents. We also work with lenders who offer specialty programs for self-employed buyers, buyers with non-traditional income, and jumbo loan borrowers in the upper price ranges of the Los Angeles market.
