Property value, appraisals & usable equity
EquityPilot's math is accurate — but the equity you can actually borrow against depends on what a lender confirms your property is worth. Here's how to think about that gap.
Why property value drives usable equity
Usable equity is the difference between your property's confirmed value and what you owe. Change the value by 10% and your usable equity changes by tens of thousands of dollars — even though your mortgage balance is identical.
Why Zillow / Redfin estimates can be off
Online estimates rely on public sales data and broad models. In neighborhoods with mixed conditions, recent remodels, or thin sales history they can be off by 5–15% in either direction. Useful for a starting point — not for committing to a financial decision.
CMA, BPO, appraisal — what each one means
- CMA — a comparable market analysis from a real estate agent. Often free, directional, not used by lenders.
- BPO — broker price opinion. More structured than a CMA, still not a formal appraisal.
- Appraisal — a licensed appraiser's formal valuation. Lender-grade only when ordered through the lender's process.
Why a lender may not use an appraisal you ordered
Lenders require independence between the borrower and the appraiser to control for conflicts of interest. Even a perfectly legitimate appraisal you paid for will typically be set aside and replaced with one the lender orders directly.
Why STR and commercial properties may be valued differently
Short-term rental and commercial properties are often evaluated on income, occupancy, and debt coverage — not just comparable sales. The same building can support very different loan amounts depending on how a lender treats its income.

How to use EquityPilot before paying for an appraisal
Use a free value estimate to run EquityPilot first. If the numbers look directionally promising, then it's worth investing in a more confident value reference. Don't pay $400–$600 for a formal appraisal until the strategy itself makes sense.
