Key Insights

What these numbers mean for you

Insight

Your estimated closing costs are $13,078 (2.9% of the home price). The national average is 2-5%.

Cash Needed

You'll need $103,078 total cash at closing: $90,000 down payment + $13,078 closing costs.

Insight

In California, closings are typically handled by a title or escrow company — no attorney fee is required, so we excluded it.

Insight

Transfer tax is estimated at the California statewide rate (0.11%). California closings are handled by escrow companies, not attorneys. Documentary transfer tax is $1.10 per $1,000 at the county level; some cities add more.

Insight

Prepaid and escrow items make up 34% of your closing costs. Property tax is collected once — 3 months into escrow — never double-counted as both prepaid and escrow.

Insight

About $400 (home inspection) is paid outside closing — budget for it, but it isn't part of your cash to close.

Pro Tip

The origination fee ($3,600) assumes 1% of the loan — adjust it to match your lender. It's often negotiable, and some lenders waive it for a slightly higher rate.

The Bottom Line

To buy a $450,000 home with 20% down, you'll need approximately $103,078 in cash at closing. That's $90,000 for the down payment plus $13,078 in closing costs (2.9% of the home price).

Frequently Asked Questions

Typically 2-5% of the loan amount. On a $400,000 purchase that is roughly $8,000-$20,000, covering lender fees, title insurance, appraisal, government recording and transfer taxes, plus prepaid property taxes, insurance, and interest.

Lender origination fees, title insurance (shop it — prices vary widely by provider in most states), and some third-party services are negotiable or shoppable. Government taxes and recording fees are fixed. You can also ask the seller for credits toward your costs.

On a refinance, usually yes — costs are added to the new balance, and you pay interest on them. On a purchase, generally no; instead you can take a lender credit (higher rate, lower cash due) or negotiate seller concessions.
