DTI, or debt-to-income ratio. Half of the mortgage approval hinges on this. The Consumer Financial Protection Bureau recommends a threshold of 43% or lower. For front-end DTI, which only considers housing costs, an ideal figure is 28% or lower. The numbers are simple, but the impact is significant.

The median home value in Chino is $772,256 (Zillow, 2026). Based on listing prices, it is $799,000, and based on appraisals, it is $740,500. While there are variations, it is reasonable to estimate it between $770,000 and $800,000.

Let's calculate based on $772,000. An FHA down payment of 3.5% is about $27,020. It is possible with a credit score of 580 or higher, but mortgage insurance will apply throughout the loan term. A 5% down payment is about $38,600. A 10% down payment is $77,200. If you cover 20%, which is $154,400, PMI will disappear. The more you increase the down payment, the lower the loan principal becomes, and as the principal decreases, the DTI also lowers. These two numbers are interconnected.

If the DTI exceeds 45%, approval becomes more difficult. Conventional loans typically operate between 36% and 45%. If you have existing auto loans or student loans, it means less room for additional debt. There are two ways to address this: prepare a larger down payment to reduce the loan principal or pay off existing debts to lower the DTI. Depending on the situation, the latter can often be quicker.

Credit scores are also considered. As of July 2026, the 30-year fixed rate is 6.59% for scores above 780, 6.66% for the 760 range, 6.75% for the 740 range, and 6.91% for the 700 range (Freddie Mac PMMS). A single point difference can change your monthly payment.

The California Housing Finance Agency's MyHome Assistance is a way to reduce down payment burdens. It supports 3.5% (FHA) or 3% (conventional) of the lower amount between the purchase price or appraisal as a subordinate loan. There are no monthly repayments. Settlement occurs when the house is sold or refinanced. First-time homebuyer conditions and completion of homebuyer education are required.

What you need to prepare is clear. Start by getting pre-approved. Organize your pay stubs and tax returns. Avoid new loans or job changes before closing, as income and debt will be re-verified during the review process. Keep a few months' worth of living expenses as reserves, separate from closing costs.

There are some easily overlooked aspects. Lenders look at employment history for the past two years. If there are gaps, explanations are needed. If a large amount suddenly appears in your account just before closing, you must clarify the source. If you receive a large sum from family, prepare a gift letter in advance. Don't just look at one lender for loan products; compare rates and fees from two or three places. The differences can change approval conditions and total costs.

Also, consider rate locks. Once your offer is accepted, it's safer to lock in the interest rate. This is especially true during times of fluctuating rates. The lock period is usually set between 30 to 60 days. If closing doesn't happen within that period, additional costs may apply. Aligning the closing schedule with the lock period is crucial in practice.

Look at reserves as well. Set aside about three months' worth of living expenses, separate from closing costs. This is because the account balance will be checked during the review process. If the balance is tight, approval may be delayed or conditions may be added.

Review the types of loans again. FHA allows for a lower down payment, but mortgage insurance will continue. Conventional loans eliminate this insurance if the down payment is over 20%. Which option is better depends on available cash and monthly payment capacity. There is no single correct answer.

The effective property tax rate in California averages around 0.71%. If school bonds or special assessments are added, the actual burden increases. When looking at school districts in Chino, refer to ratings from GreatSchools or Niche, but since boundaries change frequently, check the assigned school before purchasing.
