Both of these metrics are used to measure, or determine risk when financing commercial property or making a commercial mortgage loan.LTVThe loan-to-value ratio, or LTV, is a measure of the relationship between the loan amount and the value of the commercial real estate (collateral).Calculating the LTV helps commercial real estate lenders determine both the qualification of a borrower and the proposed terms of the debt being considered.LTV = Loan Amount / Appraised ValueBe sure to understand that the LTV will be calculated off of the appraised (market) value of the asset.

Would I be better suited trying to find a Fix N Flip, pay cash using my equity, do the work myself and then put it back up on the market or would I be better off purchasing an STR with 20% down and leveraging a loan to get some cash flow coming in then maybe pursue a Fix n Flip using the remaining equity and let the STR repay the HELOC until I sell the flip?
