Let's follow the story of a family looking for a home in Pasadena. Their credit score was in the 730 range. They had saved about 10 percent for a down payment.

The average home value in Pasadena, according to Zillow as of June 30, 2026, is $1,213,522. With a 10 percent down payment of about $121,352, the loan principal would be approximately $1,092,170.

A credit score in the 730 range falls into the 700s, which would apply an interest rate of 6.91 percent. If they could raise their credit score to the 740s, just 20 points higher, they would qualify for a rate of 6.75 percent, significantly reducing the total interest burden over the life of the loan, according to data from themortgagereports.com as of July 2026.

This family chose to lower their credit card utilization and wait a few months without any late payments before seeking pre-approval again. They confirmed that even if they kept the same down payment amount, moving up just one credit score bracket would change their interest rate.

Breaking it down by down payment percentages, an FHA loan with a 3.5 percent down payment requires about $42,473, while a credit score between 500 and 579 would need a 10 percent down payment of about $121,352. A 20 percent down payment would be about $242,704, allowing them to start without PMI.

DTI is also an important factor to check. According to the Consumer Financial Protection Bureau, a back-end DTI of 43 percent or lower is recommended, and typical loans are usually determined between 36 and 45 percent. A front-end DTI, or housing cost ratio, ideally should be below 28 percent.

To increase approval rates like this family, there is a sequence to follow. Reduce existing credit card debt to lower DTI, and get pre-approved to confirm the budget range. It's also important to provide stable proof of income with pay stubs and tax returns.

Before closing, it's advisable to avoid taking out new loans or changing jobs. Having closing costs and a separate reserve fund ready can make the approval process smoother.

Looking at taxes, the average effective property tax rate in California is 0.71 percent. Based on Pasadena's home value, this translates to about $8,616 annually in property taxes, which can vary depending on the county and assessment timing.

Pasadena, located in LA County, is also eligible for CalHFA's MyHome Assistance Program. This program provides first-time homebuyers with up to 3.5 percent of the home price as a deferred second loan, to be repaid upon sale or refinancing. The income limit for LA County is reported to be about $211,000.

Pasadena is considered one of the areas preferred by Korean families due to its strong school districts. In neighborhoods with higher school ratings, home prices and property tax burdens tend to rise, so this family also considered school districts and budget when narrowing down their options. School district boundaries change frequently, so it's advisable to check the assigned school for the specific address before signing a contract.

For families moving from out of state, it's good to know that California property taxes are assessed based on the purchase price under Prop 13, with limits on future increases. If their previous residence was reassessed annually, the calculation structure is different, which can be confusing. In popular areas like Pasadena with competitive school districts, offers may not be accepted without pre-approval.

When considering the time it takes to raise a credit score and the resulting reduction in interest burden, it's clear that managing credit scores is as important a variable as the down payment. Checking the credit report for errors before applying for a loan can also be helpful.
