About this course

A house flipping course that runs one fictional fix-and-flip deal, 418 Juniper Street, from the first offer to the sale in a spreadsheet, for new real estate investors, agents, lenders and real estate students. You estimate the after-repair value from five comparable sales with an adjusted price per square foot, calculate the maximum allowable offer with the 70% rule and with a refined version built from the deal's own costs, build a rehab budget by line item and by trade with SUMIFS and a contingency, total the monthly holding costs over the project timeline, size a hard-money loan with points, fees and interest-only payments, subtract the selling costs to find the net profit, measure the ROI and the annualised return, and stress-test the deal for a lower ARV, a rehab overrun and a two-month delay with a chart. Illustrative costs. Educational only, not investment advice. The first lab is free.
