How I Structure Short-Term Capital for Under-Contract Fix & Flips (3–4 Month Timeline

[Mitchell Coles]

Hi BP community; long-time member here.

I’ve seen a number of threads recently around capital gaps, lender hesitation, and timing issues on short-term fix & flips, especially when a project is already under contract and moving toward closing.

On 3–4 month projects, I’ve found that capital conversations tend to move fastest when the structure stays simple and the risk is clearly defined. A few principles that have consistently worked for me:

1. Underwrite for downside first

Before talking returns, I focus on:

• All-in cost relative to realistic resale value

• Margin if the timeline stretches

• Whether the deal still works without a “perfect” exit

If the numbers only work in the base case, it’s usually a pass.

2. Keep lender protection structural, not narrative

In short-term projects, lenders care less about the story and more about:

• Lien position

• Draw control

• Clear exit paths

First-position security and conservative leverage often matter more than squeezing cost of capital.

3. Separate execution risk from valuation risk

When ARV is reasonable, the real risk becomes:

• Permitting delays

• Contractor performance

• Timeline management

That’s where having scope, GC alignment, and buffers matters most.

4. Treat capital as a repeatable system

The builders and flippers I’ve seen scale don’t treat capital gaps as one-off problems — they plan for them as a recurring phase of the business.

That usually means:

• Documented processes

• Repeat lender relationships

• Short-duration projects with defined exits

Curious how others here structure short-term capital when speed matters and execution is the primary variable. Always appreciate learning how others are navigating this.
