How do you calculate fix and flip profit?

Net profit is sale proceeds after selling costs and loan payoff, minus cash invested (down payment, rehab, interest-only payments during hold, and monthly carrying costs).

What is a good ROI for house flipping?

Targets vary by market and risk. Many investors compare return on cash to alternative uses of capital and minimum hurdle rates after accounting for taxes and contingencies.

Pacific Northwest investors often underwrite with tech-job-driven rent demand in mind. Default rent inputs reflect HUD FMR data—still model downside, as job mix shifts and regulation can change outcomes faster than a spreadsheet cell. Same math as the national Fix and flip calculator; numbers are educational—not lender instructions.
