But, if you're analyzing lots of deals, 9% of ARV is probably going to be a lot quicker to compute than 10% of total costs (as adding up total buying, holding and selling costs typically takes a bit more time).Sorry to be pedantic, but the engineer/mathematician likes both accuracy and precision...  :-)

I have really complicated ones that try to compute everything precisely.

From what I've seen, allot of the numbers people come up with are super precise and the overage or shortfalls are a SWAG (Scientific Wild A$$ Guess).  

Hey guys,I know there's a lot of posts about foundations and it's very difficult for people to give specific / precise answers, but a ballpark idea would be really helpful.I looked at a bungalow today where the first floor is dated but not in a bad condition at all.

In fact, that's precisely what I've been doing at our house now preparing for the sale.

This is precisely why I joined the BP community.  

Since then, and simply put our company and mine experience will speed up the screening process with precision, instead of hunting down we educate our select buyers, sellers and investors.

Don't cut it so close you can't sleep at night.You may be able to get the 3-unit under contract with a contingency of selling your flip, but that will probably make your offer less competitive.Otherwise, I would wait until you at least have your flip under contract (and have a more precise expectation of net proceeds) before going shopping again.The 3-unit property is not a one-in-a-million opportunity that just happened to pop up right now. 

But, you really need to know the fine details in order to put yourself in a safe financial situation based on precise location selection.

Fannie Mae does not specify the precise documentation the lender must obtain to verify that a non–U.S. citizen borrower is legally present in the United States.
