If you don't know i can make some guesses just for illustration purposes. 

The tax code/regulations do not define or illustrate when one activity is insubstantial in relation to another.

Illustration.

Going to have to fine tune that with my CPA ...To give credit where credit is due, here is an article that gave me some good ideas and illustrates how this may work:http://www.gocurrycracker.com/the-go-curry-cracker...

The financing used for the illustration is non-recourse at 60% LTV at 4.75%.Cash Purchase:Total Cash Invested:$124,800Total Property Price:$124,800Yearly Cash Flow: $7,437Annual Cash on Cash Return:6%Financed Purchase:Total Cash Invested:$52,980Total Property Price:$124,800Yearly Cash Flow: $7,437Annual Cash on Cash Return:14%These numbers are net and include taxes, HOA fees, insurance etc.

I was trying to illustrate that while you might be able to build a credit rating as far as having loans were concerned you somewhat offset that by increasing your debt to income which lowers your credit score.I have found that in most cases if you make a large enough down payment you will find someone that will make the loan you want.

Below is a diagram illustrating the cost difference between direct vs. turnkey.

Assume the following:PV = $100,000nPer = 360PMT = ($699.21) - ensure this number is always negative when used as formula inputRate = 7.5%For concept illustration purposes let's look at RATE:Rate = ([nPer,PMT,PV,,.1) (I always just plug the guess in at 10%)RATE = 7.76%This rate will be off slightly because the final payment in the amortization schedule is not handled correctly.
