Multiply that x number of months you'd have this guy stay.. 

Just like sellers and listing agents might assume an FHA buyer has a rock bottom FICO, they might also assume they are barely scraping together 3.5% down, since many do in fact multiply target sales price by 3.5% and save up exactly that much money, unaware of closing costs, that things break in homes after you buy them, etc."

Multiply by .8 and you'll know what 80% of market value is.

However the "1% rule" is a form of gross rent  multiplier.

Hi Alan,I convert  two  SFR into duplexes in Barrie. its a great way to improve  cash flow and add value. just like  the rest of the GTA, prices went up dramatically with multiply offer craziness Toronto style, until around March /April 2017. 

Calculate the NOI by multiplying the number of spaces by the lot rent, and then multiply by 12 months, subtract the expenses (can range from 30-50%, that % depending on the variables above). 

A lender friend of mine told me they multiply the purchase price (or ARV if you refinance post-reno) by .0033 for the yearly premium for homeowner's insurance.

Multiply that or divide it however you choose to calculate how much you have lost in revenue.Those are dollars you would have lost to save what ???????????

If I had your $360,000 and multiplied it into 3.6 properties of the same value I would have $14,400 positive cash flow per month.That is how leverage works when done properly.

@jamesTo expand on what @Linda Weygant said about the home office deduction no longer being an audit flag, the IRS now allows a "simplified" method where you simply multiply the square footage of the office by $5 and that's your deduction.One has to think that if the IRS is offering and encouraging a simplified method of reporting, it's not going to be the cause of an audit.
