Fix and flip loans get lumped in with "hard money" so often that investors sometimes assume they're the same product. They overlap, but a good flip loan is built around a specific structure: purchase money, a rehab budget, and a lender who releases the rehab funds as the work actually gets done. Here's how the pieces fit together.
The basic structure
A fix and flip loan typically funds two things in a single loan:
- Purchase price — funded at closing, like any acquisition loan.
- Rehab budget — held back by the lender and released in draws as renovation work is completed and verified.
This is different from a conventional mortgage, which only finances the purchase and assumes the property is already in move-in condition. Flip loans are built for property that isn't — that's the entire point.
What is ARV, and why does it matter more than purchase price?
ARV (After-Repair Value) is the estimated market value of the property once renovations are complete. Most fix and flip lenders size the loan primarily off ARV, not the purchase price — because the collateral that ultimately secures the loan is the finished product, not the distressed property you're buying today.
A lender will typically order (or review) a comp-based valuation to estimate ARV before finalizing terms. Your renovation budget and scope of work directly influence that number, which is why a realistic, well-documented rehab budget matters as much as your purchase contract.
Illustrative example
Purchase price: $220,000. Rehab budget: $60,000. Estimated ARV after renovation: $360,000.
Total project cost: $280,000. Lenders generally want to see meaningful equity built in relative to ARV before they'll finance the deal — the exact leverage available depends on the lender, your experience, and the specific property.
This is a hypothetical example for illustration only, not a quote.
How draws work
Rehab funds aren't handed over up front. Instead:
- You (or your contractor) complete a phase of work — say, demo and framing.
- You request a draw, usually with photos or an inspection confirming the work is done.
- The lender (or a third-party draw inspector) verifies the work.
- Funds for that phase are released, typically within a few business days.
This protects both sides: the lender isn't funding work that hasn't happened, and you're not carrying the full rehab budget in cash before you need it. The tradeoff is that you (or your contractor) need to front the cost of each phase before the draw reimburses it — which is why realistic cash-flow planning across the project matters as much as the loan terms themselves.
Timeline: why speed matters
Fix and flip loans are short-term by design — usually structured around a 6 to 18 month hold, matched to a realistic renovation and resale timeline. That's a feature, not a limitation: the interest clock is running the entire time you hold the property, so a tight, well-planned project timeline directly protects your margin. Before you close, it's worth mapping out:
- Realistic renovation duration, including permit and inspection lead times
- Contractor availability and a backup plan if it falls through
- Expected time on market once the property is listed
- A buffer for the unexpected — because there's almost always something
Bank vs. broker for flip financing
Most traditional banks don't offer fix and flip products at all — the short hold period and distressed collateral don't fit their underwriting model. That's why flip financing runs almost entirely through private lenders and brokers who specialize in business-purpose, asset-based loans. A broker with access to multiple flip lenders can typically compare leverage, draw process, and speed across several programs rather than presenting you with a single take-it-or-leave-it structure.
Common mistakes that slow down or sink a flip loan
- Underestimating the rehab budget. A thin contingency can turn a profitable flip into a break-even one once the loan clock is running.
- Vague scope of work. A detailed, line-item renovation budget gets you a faster ARV review than a rough estimate.
- No contractor lined up before closing. Draws can't start until work does.
- Ignoring exit timing. Know your loan term and work backward from it, not forward from your renovation start date.
Getting started
The numbers a lender will want first: purchase price, estimated rehab budget, and your estimate of ARV. If you have comps or a contractor bid already, even better — it speeds up the review considerably.
