Take these monthly expenses and subtract them from a rental payment and you have your general cash flow.

@Adam BossenI coach wholesalers scale their wholesaling business by using their same marketing dollars and doing more with those dollarsThere are deals out there but you throw the leads awayFor instance let's say you had a light rehab and 100,000 needed 5000 work70% of the hundred thousand 70, subtract 5000 for the work, and subtract 5000 for the Wholesaling fee and you left with 60You can JV with that particular home seller and use your money to fix it up; you figure out the closing costs and sales costs, get private lender money and pay the interest, fix it and resell, you pay the homeowner when it resells, no payments to the homeowner until it sellsSay it costs 10% to sell, 5000 in work, 10,000 in a JV fee, net to the seller on the joint venture is 75k, better than the Wholesaling offerFor houses that have no equity but they're pretty and don't need work, are in good areas and have good schools and low crime, you can buy on subject to, buy on a wraparound mortgage, or do a lease with option and then assign the deal.

Installment sale, give him 105% of value, get the payment half of market rent, rent it out or give him market rent until he dies but no payments, just subtracted fro note as valuable consideration.The key to older people selling installment sales is:If you got all your cash today, what would you do with it?

You would take the gross sale price and subtract routine selling expenses such as broker's commission, closing agent fees (escrow, title or closing attorney), recording fees, etc. 

That is why the material list is important because it allows you to easily subtract the material cost from the estimate to calculate labor cost.

Subtract desired capital gains.

Why subtract another 10% of ARV (which I'm assuming is meant for your profit) which seems to duplicate your "Your preferred profit".  

Subtract 10% for transaction costs.

This is used by flippers to determine how much is leftover after the sale price which you then subtract the rehab costs and purchase price to arrive at your profit.  

To get an even higher rent you can credit them a percentage of their rent and subtract it from the sales price.
