How a conventional loan can work for a move-up purchase
A conventional home loan is made through a private lender and is not insured by the federal government. It can be structured with different down payments, subject to the loan program, property, and borrower qualifications. A larger down payment may reduce the amount borrowed and, depending on the loan structure and applicable guidelines, may affect whether mortgage insurance applies.
Approval and available terms also depend on credit history, income, assets, existing debts, and property details. For a move-up purchase, compare more than the amount you can put down: consider how sale proceeds, cash reserves, possible mortgage insurance, and the timing of both transactions fit together. A loan comparison can help clarify the trade-offs, but an estimate is not an approval or a guarantee of particular terms.
Any approval or eligibility is subject to credit approval and program guidelines. Build the comparison around the property and offer you are considering, and revisit it if your sale proceeds, expenses, or timing assumptions change.

Tustin’s price scale and your down-payment plan
Tustin’s home value was estimated at $1,157,866 in August 2026 (Zillow Research, August 2026). It is a market estimate, not a sale price or a valuation of a particular home, but it shows why move-up buyers should test down-payment plans against realistic sale proceeds and the price of the next property.
Check the loan amount against the Tustin property
For a one-unit property, the 2026 conforming loan limit in Orange County is $1,249,125 (FHFA Conforming Loan Limits, 2026). Compare the actual loan amount—not the estimated value of the home—with that limit. The amount you borrow depends on the purchase price and down payment, while eligibility also depends on the borrower, property, and applicable guidelines.
A larger down payment may bring the loan amount down, but using more cash upfront can leave less for moving, repairs, reserves, or a gap between closings. Compare scenarios using verified funds rather than assuming an online estimate will become available as sale proceeds.
Use Tustin’s market activity as context, not a sale prediction
Tustin had 141 homes for sale in August 2026 (Zillow Research, August 2026), while 32.35% of listings had price cuts that month (Zillow Research, August 2026). These figures can inform a conversation about the market as you estimate proceeds from your current home, but they do not predict your home’s sale price or how long it will take to sell.
For a move-up plan, estimate net proceeds by starting with a realistic sale-price range and subtracting the mortgage payoff and transaction costs. Keep room in the plan for a lower offer, a longer sale, and a period when you may be responsible for two housing payments.
Coordinate the sale and purchase timing
Tustin homes went to pending in a median of 27 days in August 2026 (Zillow Research, August 2026). That market-level measure is not a prediction for your property, but it underscores why a move-up buyer should discuss timing before relying on sale proceeds for a new down payment. Coordinate closing dates with your agent and ask early how an unsold home and its mortgage would factor into the financing review.
Options to discuss may include coordinating closings, a sale contingency, or financing approaches that reduce reliance on immediate sale proceeds. Availability, cost, terms, and qualification vary; plan for the possibility that your current home takes longer to sell than expected. I’m most useful when I compare conventional loan pricing across down-payment scenarios and the full cost picture.
Update your plan as Tustin listings change
Tustin had 45 new listings in August 2026, down 13.46% from the prior month (Zillow Research, August 2026). That is context for the month, not a forecast of what will be available when you are ready to buy. Recheck your purchase options as your current home is prepared, listed, and receives offers, and use property-specific costs rather than a market estimate to set your budget.
Can I get a conventional mortgage with 3% down?
Some conventional programs allow a qualified buyer to put 3% down, but eligibility depends on the program and borrower. In Tustin, compare the actual purchase price and loan amount with the $1,249,125 one-unit conforming loan limit for Orange County (FHFA Conforming Loan Limits, 2026); the local home-value estimate of $1,157,866 is not a quote or a specific property’s price (Zillow Research, August 2026). A lender can review your qualifications and the property to see which options may fit.
Is a conventional loan better than an FHA loan for me?
Neither is automatically better; compare the programs against your finances, property, down payment, and loan terms. For a one-unit property in Orange County, the 2026 FHA loan limit is $1,249,125 (HUD CHUMS FHA Forward Mortgage Limits, 2026), and the one-unit conforming loan limit is also $1,249,125 (FHFA Conforming Loan Limits, 2026). Those limits alone do not determine which loan is right for you, so compare the full costs and eligibility for the Tustin home you are considering.
