How is this multiplied to maximum effect?

There is a risk factor and that multiplies the more doors you have, but if you buy right and value add.

The amount that you will actually receive, in a partial loss, will be arrived at by multiplying the claim value by a ratio, with the ratio being: insurance amt divided by (80% of replacement value), assuming 80% is your coinsurance percentage.And guess what, the likelihood of a partial loss is many times greater than the likelihood of a "full burn down".This is how it has been explained to me.

For a quick reference when I run my estimates, I take the bottom floor square footage divide by 49 (as piers are supposed to be no further than 7 feet apart on a single story) then multiply by $350.  

Leverage can be very useful but also multiplies your risk. 

But I probably could not be happier with taking a chance on F&G.Like a few others, I came across F&G through Morris Invest and figured that I would get 3-4 "rounds" of applying for business credit and assumed that each round would multiply previous acquired credit by 1.5 or 2X.

That also means that you multiply the issues which are already amplified by the distance.

I didn't do the math, but it looks like if you add up your PITI and any other monthly expenses and multiply by the number of months of rehab, you get the holding costs.

Imagine $120.00 a door that  is closer to what I am getting multiplied by 1000 front doors equals $120,000 a month multiplied by 12 months equals $1,440,000.00 right?

If you are new to flipping, the good rule of thumb is whatever your renovation estimate is, multiply it by 2 and that's your real number.
