Multiply that value times .70 and this is the estimated value not including repairs. 

Now instead of doing it all on your own you have multiplied yourself in all ways.  50 % of something is better than 100 % of nothing, right?  

So divide 100/5.22=19.15 this is your multiplier. 19.15x NOI should be the sales price.

Divide NOI by the total investment cost (asking price + repairs), then multiply by 100 to get Cash-on-Cash Return (CoCR). 

This is calculated by multiplying the loan amount x .0035.

At the end for a rough estimate I just multiplied all my material cost by 2 and the numbers seemed to make sense.

For vacancy, just try multiplying #2 X 11 (assuming 1 month each year that you're not collecting rent).6.

(I.e. gross rent multiplier, cap rate, price per unit, etc).
