Summary
Zoom Casa's Cash Offer + is structurally the cleanest version of the “upfront advance plus waterfall” model we've analyzed. The mechanics are simple enough to fit on one page: the program closes on the home at 85% of an independent appraisal, the seller keeps their own agent, the program lists the property at the appraised value, and 100% of anything above the reserve flows back to the seller at the second closing. The base fee is 4.99% of the final sale price. Carry is 0.75% per month while the property is on the market, capped at 4.5% over six months.
What separates Zoom Casa from the five other programs in the category isn't the advance rate or the base fee — they're within 50 basis points of the field. It's two specifics: the waterfall is 100% to the seller (no program share above the reserve), and the PSA explicitly names the appraiser and the listing-price methodology. That's rare.
How it works
The flow from a seller's perspective runs in three steps. First, the seller applies through their own agent; Zoom Casa orders an independent appraisal within 72 hours and issues a firm advance offer at 85% of appraised value. Second, the first closing happens at the appraisal-based price; the seller receives 85% of appraised value minus any liens and the program's escrowed fees. Third, the program lists the home with the seller's agent at the appraised price, and on the second closing the seller receives 100% of the overage above the reserve, minus the base fee and any accrued carry.
The seller's agent represents the seller on both legs. Zoom Casa does not take the listing in-house — which is the single most underrated feature of the product, because it preserves the agent's fiduciary and keeps the listing marketed the way it would have been marketed anyway.
Fee stack
Assuming the $525,000 sample transaction, a 45-day average time-to-retail-close, and the appraisal hitting $525k:
| Appraised value | $525,000 |
| Upfront advance (85%) | $446,250 |
| Base fee on retail close (4.99%) | −$26,198 |
| Carry (45 days ≈ 1.5 months × 0.75%) | −$5,906 |
| Seller's agent commission (2.5%) | −$13,125 |
| True-up to seller (100% of overage) | $71,979 |
| Total to seller | $472,500 |
The effective discount to a theoretical retail sale (at the same price, netting agent commission only) is about 3.9%. That is noticeably tighter than any iBuyer (10–18% effective discount) and comparable to or slightly better than every other Cash Offer Plus program in our review set.
PSA analysis
The current Zoom Casa Purchase and Sale Agreement is 18 pages. The clauses that matter for a seller evaluating the product are on pages 3, 7, and 12.
- Section 2.3 (“Valuation”) names an approved appraisal panel and requires a second appraisal if the first falls more than 8% below the seller's requested list. This is a real protection against a lowball first number.
- Section 5.4 (“True-Up”) defines the overage as “gross second-closing sale price minus base fee, minus accrued carry, minus buyer credits not exceeding 1% of sale price.” Critically, it does not carve out marketing costs, staging, or listing-side items.
- Section 7.1 (“Listing Control”) gives Zoom Casa the right to reduce the list price by up to 3% every 30 days the home remains unsold. That's a fair carry-containment mechanism but worth knowing before signing.
Pros and cons
Pros
- Highest waterfall share to seller in category (100% above reserve)
- Seller keeps their own agent on both legs
- Independent appraisal with second-look right
- Carry capped at 4.5% total
- Live in all 50 states
- PSA is specific about the true-up definition
Cons
- 85% upfront leaves 15% waiting on the waterfall true-up
- Price-reduction right can pressure a slow market
- Affiliate-assignment clause in PSA is broad
- Monthly carry accrues even during repair credits disputes
Who this program is for
Zoom Casa is our default recommendation for sellers who want Cash Offer Plus economics without a narrow state footprint. If you're in one of the markets where it operates — which is everywhere — and you have an agent you trust, this is the first program you should put in the side-by-side builder.
It is not the right product for: sellers who need to close in under 10 days (iBuyer is faster), sellers who prefer the certainty of a fully-documented firm advance (HomeLight's 70% structure can be simpler), or sellers in states with unusual transfer-tax structures where a two-closing product carries double cost.
Verdict
9.3 / 10. Zoom Casa is the clearest implementation of the Cash Offer Plus model currently available in the U.S. It wins on transparency (25% of our rating), ties on net proceeds (40%), leads on seller control (20%), and is the only program in the category that scores maximum marks on state availability (15%). If you're choosing between programs and nothing specific is pulling you somewhere else, this is the one.
Alternatives to consider
- HomeLight Cash Offer — If a firm 70% first-close number matters more than a 100% waterfall share.
- QuickBuy Immediate — If you're working through a specific partner brokerage.
- Opendoor Cash Plus — If you're in the pilot markets and speed beats optimization.
