Do +/-1 bedroom, etc.....Come up with a After Repair Value you think makes since.B) subtract the amount you want to earn in equity (10k, 20%, etc...). 

I often see a 2% selling cost subtracted from a residual value in the direct cap or DCF valuation method for commercial deals.  

I might assume 2-5% depending on the age of the house and condition.Take the yearly rent (1400*12=16800) and subtract your maintenance and vacancy costs of 10-13% (16800*.90 = 15120/yr).

Using the 70% rule ARV is 190K x 70% =133K then you have to subtract all the cosmetics and mold remediation so yes 145K is way overpriced.

Just take 80% of the value of your home then subtract your mortgage balance.

They also update the packet each year to add or subtract forms as needed.As for contractors, your text cut off. 

Similarly to measure how much you are getting ahead of the game, you should subtract out interest payments, which are the cost of not falling behind -- they don't put you ahead of the game.

Without knowing the full facts here, I cannot say how much tax your co-workers' in-laws will owe, but basically it would be a calculation to the effect of this: add up the decedent's full value of assets owned at death, add up any prior gifts made during the decedent's lifetime that exceeded the annual exclusion, and subtract out $5.49 million. 

Subtract that from the NOI to get cash flow.

Wholesaling to a flipper certainly has to be priced allowing a profit for the flipper, not necessarily at 70%, you need to put a pencil to it beginning at the ARV, then back off to a probable sale price, then subtract his profits, costs of repairs, holding costs, transaction costs to get to you number of what you sell for, take out your fee and follow the same costing approach to get to an offer.
