A model home is staged to make the decision feel easy. The paperwork behind it is less simple: the builder writes the contract, the house may not be built yet, and the monthly cost depends on dues and special taxes that never appear in the base price.
These are the five questions Rudy Flores hears most from buyers touring new communities around San Diego County, from the Otay Ranch villages in Chula Vista to Epoca in Otay Mesa and Civita in Mission Valley, in roughly the order they come up.
1. Can I bring my own agent to a builder's sales office, and when?
Yes, and the timing matters more than most buyers expect. Many builders only work with a buyer's agent who is registered on your very first visit, and policies differ from builder to builder. Walk in alone and register yourself, and you may not be able to add an agent later, so reach Rudy before you go or bring him along.
The sales representative is usually helpful and well informed, and is paid by the builder. A buyer's agent works only for you: reading the builder-written contract with you, comparing communities, weighing lot premiums and upgrades, and checking the new home against resale homes nearby.
Builders set their own policies on paying a buyer's agent. Before you tour, Rudy tells you in writing how he is paid and whether the builder is covering it. He is part of the Patti & Jeff McKelvey Team; Patti worked in real estate with McMillin, one of the builders behind EastLake's earliest neighborhoods, and the team has worked with builder sales offices around the area.

2. Is the builder's incentive worth using the builder's lender?
Sometimes, and the only way to know is to compare on paper. Builders often offer a credit, a rate buy-down or upgrades if you finance with their preferred lender, and the fine print usually ties it to a contract date, a closing date or both. Ask what the incentive requires and what it is worth in dollars.
Then get an outside quote for the same loan. Every lender issues a standard three-page Loan Estimate, which the CFPB says should arrive within three business days of applying, and because the form is identical everywhere you can set two offers side by side: rate, APR, points and fees. Some months the builder's package comes out ahead, and some months an outside loan does.
For context, the Freddie Mac 30-year average stood at 7.32% in the week of October 22, 2026, against 6.19% a year earlier (week of October 23, 2025), with the 15-year average at 6.68%. If a buy-down lowers your rate only for the first years, ask exactly when it ends and what the payment becomes. You are always free to choose your own lender.

3. Do I really need an inspection on a brand-new home?
An independent inspection is still worth considering. New homes can have defects too, and the final walkthrough is led by the builder's own representative. An inspector you hire answers only to you.
If the house is still going up, ask whether you can visit at key stages and arrange an inspection before the walls are closed, while framing, wiring and plumbing are still visible. At the walkthrough, test the doors, windows, outlets, faucets, appliances and heating and cooling, then put every item on a written punch list with photos and a promised repair date.
Learn the warranty before you need it. Builders provide their own warranties, and California's Right to Repair Act (Civil Code section 895 and following) sets building standards for new homes and a process for claims. Rudy can point you to the right questions; an attorney can advise on your rights.

4. How long will the build take, and how do I plan my move around it?
It depends on the home and the phase. Some homes are finished and ready now, others are not started, and villages such as Côta Vera in Otay Ranch are building out in phases. Ask which homes are move-in ready, when the last home in your phase is expected and what the contract says happens if completion slips.
The date shapes your financing. Pre-approvals often expire after 60 to 90 days, and a rate lock runs on its own clock, so ask your lender how a lock works on a home that may close months from now and what an extension costs. Keep your lender updated and your finances steady while the house is built.
If you are also selling a home, build in a cushion. Ask about the deposit schedule and whether money for options and upgrades is refundable, then count back from the expected closing to line up the sale, the movers and the utilities.

5. What will HOA dues and Mello-Roos add to my monthly cost?
Newer communities often carry both, so put them in the budget at the first visit. HOA dues pay for shared spaces such as a pool, landscaping, private streets or the outside of a condo building. Mello-Roos is a special tax charged in a Community Facilities District, billed with your property tax, that pays for streets, parks and other public improvements.
Unlike the base property tax, a Mello-Roos tax is not held to Proposition 13's 2% yearly cap; how it can change and when it ends depend on each district's own rules. Ask the sales office for the Notice of Special Tax and the total property tax rate, plus the current dues, the reserve funding and any planned increases.
Then compare total monthly cost, not sticker price. As a benchmark in Epoca's ZIP code, Zillow's typical value for all homes in 92154 was $745,539 as of September 2026, up 1.7% from a year earlier; with 20% down and the 7.32% average rate from the week of October 22, 2026, the monthly principal and interest on that price would be about $4,097, before property tax, insurance, dues and special taxes. A new home with a higher special tax can cost more or less each month than an older one nearby, so run both through the same calculator.
