And who also understands that you're looking at metrics like cash flow, gross rent multiplier, gross annual yield, the 1% test, appreciation, rental growth, and cash-on-cash return?

Sum the rents for the month and multiply by 12 -> annual GSI.GSI - Expenses -> NOINow take P+I from your loan and divide that into the NOI -> DSCR.When the DSCR > 1.3, you can get a commercial loanIf you can't get 1.2-1.3 then it's doubtful that you have anything worth chasing.

Why are you multiplying (ARV-1.5xHighEstimate) * .7?  

Shouldn't you be multiplying by 6 instead of two?

As shown above, your effective ROI is multiplied with a mortgage on the property.

Typically 6 months of reserve, but as you can guess, this becomes multiplied by how many mortgages you have.

There are a few ways to do this for SFRs, but what people typically do is take the total basis (not just the purchase price; you have to make various additions for closing costs, etc.) and multiply it by how the county assessor's land percentage (i.e., assessor's "land value" over assessor's "total value").  

Based on the above, you would think the 4 unit should be valued just under $70,000, but there is that last comp, property #4, would when multiplying it's $ per sq.ft. by 2988, comes in at $97,498.  

If I multiply this by my purchase price, I get a land value of $52,700.

SO if you multiply my numbers through, I must make 4 x 5 x 3 attempts to make profit (i.e.60 contacts).
