FAQ

Common questions

What is a good cap rate?

4–5% for core institutional assets; 6–8% for value-add properties; above 8% for opportunistic or distressed investments. Location and asset type matter significantly.

Does the cap rate include financing costs?

No. Cap rate is a financing-agnostic metric. It assesses asset return independent of how it is funded. Debt service is excluded by design.

Why does the flip calculator use 6.5% for holding cost?

It estimates a bridge financing cost. If you are using cash, holding costs are lower — adjust your inputs accordingly to reflect your actual financing rate.

Are agent commission rates fixed?

No. They vary by market, agent, and negotiation. 2–3% per side is typical in the US. Enter your actual expected rate for an accurate projection.

Does flip ROI account for taxes?

No. Tax on short-term capital gains (flips held under 1 year) can significantly reduce net return. Consult a tax advisor before projecting final returns.
