When evaluating a fix-and-flip property, how do you estimate the rehab budget before committing to the purchase?
I'm interested in how investors account for hidden repairs, holding costs, and financing expenses when determining whether the deal has enough room for profit.
What's your process for deciding whether a flip's numbers are realistic?
Coming from a construction cost management background, I’d approach it by building a detailed scope of work and cost estimate before committing to the purchase, then stress-testing the numbers.
On the commercial side, I’ve worked with cost forecasting, change orders, contingency tracking, contractor costs, and project reporting on large-scale projects. I’d apply that same discipline to a rehab by breaking the scope down by trade, validating pricing with contractor quotes, identifying high-risk items early, and tracking committed costs against the budget throughout construction.
I’d also account for holding costs, financing, permits, and a contingency for unforeseen conditions rather than relying on the initial rehab estimate alone.
Ideally, I’d want to inspect the property thoroughly before closing and distinguish between cosmetic work and potentially expensive items like roofing, plumbing, electrical, and structural repairs.
Ultimately, I’d evaluate the deal using a conservative all-in cost and resale value, then work backward to determine my maximum purchase price. The goal is to protect the margin before buying, not try to make the numbers work after the fact.
I’m looking to apply my cost management and project controls experience to residential value-add investing, so I’m interested in learning how experienced investors validate their estimates in the field.
