Monthly Holding Cost $150
Total Holding Cost (6 months) $900

Holding costs are often underestimated by new flippers. Every extra month on a hard money loan at 12% adds significantly to your all-in cost. Budget an extra 1-2 months beyond your expected timeline as a buffer.

Why holding costs matter

Holding costs are the silent deal killer for fix-and-flip investors. A flip that takes 6 months instead of 4 adds two extra months of mortgage payments, taxes, insurance, and utilities. On a hard money loan at 12% interest, that could be $2,000-$4,000 in unexpected costs that eat directly into profit.

When marketing deals to flip buyers, including a holding cost estimate in your deal package shows sophistication and helps the buyer calculate their true all-in cost. See our marketing package guide for what to include.
