Part of our Vacaville home loan guides: Conventional loans across California · FHA loans in Vacaville · First time buyers in Vacaville · VA loans in Vacaville
Quick answer: A conventional loan in Vacaville lets you buy with as little as 3% down, up to the 2026 Solano County conforming limit of $832,750. You pay private mortgage insurance (PMI) only if you put less than 20% down, and you can remove it later. Most lenders want a 620 credit score or higher. With Vacaville’s August 2026 median sale price of about $610,000, a 20% down payment is $122,000, and a 3% down payment is about $18,300.
Conventional loans are the most common way people buy homes in Vacaville. They are not backed by a government agency, which gives them flexible terms, removable mortgage insurance, and no upfront funding fee. If your credit is solid, a conventional loan is often the lowest long term investment.
As an independent mortgage broker based in Solano County, I compare conventional loans across many wholesale lenders, so you see more than one bank’s rate sheet. This guide uses real 2026 Vacaville numbers so you can see what buying here actually looks like.
Vacaville Housing Market Snapshot for Conventional Buyers
| Vacaville number | Figure | Source |
|---|---|---|
| Median sale price | $609,597 (August 2026, down 3.2% from a year earlier) | Redfin |
| Median days on market | 36 days | Redfin |
| Sale to list price | 100% | Redfin |
| 2026 conforming loan limit, one unit | $832,750 (Solano County) | FHFA |
| Median effective property tax rate | About 1.18% | Ownwell, April 2026 |
Homes in Vacaville are selling at about list price, so a strong preapproval and a clean offer matter. Prices dipped slightly over the past year, which gives buyers a little more room to negotiate than the Bay Area does.
Conventional Down Payment Options in Vacaville
Here is what different down payments look like on a $610,000 Vacaville home, close to the August 2026 median.
| Down payment | Cash down | Loan amount | PMI? |
|---|---|---|---|
| 3% (HomeReady or Home Possible) | $18,300 | $591,700 | Yes, reduced coverage |
| 5% | $30,500 | $579,500 | Yes |
| 20% | $122,000 | $488,000 | No |
Property taxes in Vacaville run about 1.18% of the purchase price each year. Plan for homeowners insurance too. PMI depends on your credit score and down payment, so I price it from real lender pricing instead of guessing.
3% Down With HomeReady and Home Possible
Fannie Mae HomeReady and Freddie Mac Home Possible let you buy with 3% down if your income is at or below 80% of the area median income for the property’s location. You do not have to be a first time buyer. If every buyer on the loan is a first time buyer, one of you completes a homeownership education course. These programs also use reduced mortgage insurance coverage, which can lower your monthly payment.
Need help with the down payment too? Some Vacaville buyers pair a CalHFA conventional loan with CalHFA MyHome assistance. See my Vacaville first time buyer guide for details.
Conventional Loan Requirements
- Credit score: 620 minimum for most programs, with better pricing above 740.

- Debt to income ratio: generally up to 45%, and up to 50% with strong credit and reserves through automated underwriting.
- Loan amount: up to $832,750 in Solano County for a one unit home in 2026.

Conventional vs FHA in Vacaville
| Conventional | FHA | |
|---|---|---|
| Minimum down payment | 3% | 3.5% |
| 2026 Solano County loan limit | $832,750 | $685,400 |
| Mortgage insurance | PMI only under 20% down, removable | Upfront 1.75% plus annual premium, often for the life of the loan |
| Credit score | Usually 620 or higher | 580 for 3.5% down |
| Best fit | Good credit, any down payment | Lower scores or higher debt ratios |
If your score is under about 680, an FHA loan in Vacaville may give you a lower payment. If you are a veteran, compare both against a VA loan in Vacaville, which needs no down payment and no monthly mortgage insurance.
Property Taxes and Mello Roos in Vacaville
Your property tax is based on your purchase price, not the seller’s old assessed value. It starts at 1% under Proposition 13, plus voter approved bonds and assessments. Some newer Vacaville subdivisions sit inside a Community Facilities District, known as Mello Roos, which adds a separate special tax. Lenders count that tax when they qualify you, so two homes at the same price can lead to different approvals. I always pull the actual tax bill for the address before you write an offer.
When a Conventional Loan Makes the Most Sense
- Your credit score is around 700 or higher.
- You can put 5% or more down, or you qualify for HomeReady or Home Possible.
- You want mortgage insurance that goes away.
- You are buying a second home or an investment property in Vacaville.
Frequently Asked Questions
How much do I need to put down on a conventional loan in Vacaville?
As little as 3% through programs like Fannie Mae HomeReady and Freddie Mac Home Possible, which have an income limit of 80% of area median income. Without those programs, many buyers put 5% to 20% down. On the August 2026 Vacaville median sale price of about $610,000, 3% down is about $18,300 and 20% down is $122,000.
What is the 2026 conforming loan limit in Vacaville?
Vacaville is in Solano County, where the 2026 conforming loan limit for a one unit home is $832,750, set by the Federal Housing Finance Agency. Loans above that amount are jumbo loans with different rules.
Do I have to pay PMI on a conventional loan?
Only if you put less than 20% down. Unlike FHA mortgage insurance, private mortgage insurance on a conventional loan can be removed. You can request cancellation once your balance reaches 80% of the original value, and it drops off automatically at 78% under the Homeowners Protection Act.
What credit score do I need for a conventional loan?
Most conventional loans require a minimum credit score of 620. A higher score lowers both your rate and your PMI, so it is worth reviewing your credit before you shop.
Is a conventional loan or an FHA loan better in Vacaville?
It depends on your credit and down payment. Conventional usually wins with a score around 700 or higher because PMI is cheaper and removable. FHA can win with lower scores. I run both side by side so you can see the real monthly numbers.
How are property taxes calculated when I buy in Vacaville?
California property tax starts at 1% of your purchase price under Proposition 13, plus voter approved local charges. The median effective rate in Vacaville is about 1.18%. Some newer Vacaville subdivisions also carry a Mello Roos special tax, so always check the tax bill for the specific address.
Examples are illustrations only, not a loan offer or rate quote. Rates change daily and your actual terms depend on your credit, income, property, and the lender.
