Frequently Asked Questions

What is a good IRR for a real estate investment?

Most real estate investors target 15–25% IRR for fix-and-flip deals and 10–18% for long-term hold strategies. IRR accounts for both cash flow and equity buildup over time, making it the most complete return metric. Our template calculates IRR automatically.

How do you calculate if a fix-and-flip is profitable?

Maximum offer = (ARV × 0.70) − Rehab Costs − Holding Costs − Selling Costs − Desired Profit. Our template calculates this automatically and flags deals that don't meet your minimum profit threshold.

What's the 70% rule in house flipping?

The 70% rule says never pay more than 70% of the After Repair Value (ARV) minus rehab costs. This leaves a buffer for holding costs, selling fees, and unexpected overruns. Our template uses this rule to calculate your maximum allowable offer.

Does the template work for BRRRR deals?

Yes. The investment property template includes a dedicated BRRRR analysis tab with refinance proceeds calculation, maximum LTC and LTV inputs, and the complete buy-rehab-rent-refinance-repeat cash flow sequence.

Is this a one-time purchase?

Yes — pay once, use forever. The template is yours to use on unlimited deals. No subscription, no recurring fees.
