Although we most always use shingles with some color variations rather than a solid color.If you take a picture standing in front of the house, it will be easier to see how it ties in to give a better opinion of the "package".

Here's me and my prize winning stockdogs at a trial.

Property is $179,000 for a 5 Bedroom Multi-Family home. They said the total income is $2075 for rents ( Based on a site) $2075 * 50% Rule = $1037.5 20% of 179,000 is 143,200 @ 4% interest Rate makes the Mortgage $683....

Took a lot of trial and error to figure out what was optimal for me.

It might take some research and some trial /error to figure this out. 

There can be significant variation in pricing from foundation companies.

oh good point @Gordon Cuffe I suppose it would have to be a bit of a variation on BRRRR, where I buy a destressed property with a FHA and work on the rehab as I go.

Other lenders offer asset depletion, for those who have substantial net worth but still prefer to take a loan instead of paying cash.There are lenders that offer one or two variations on the regular Fannie Mae/Freddie Mac guidelines in exchange for higher rate and lower LTV.  

Seems like there is a variation of this theme on this thread.

For example, I recently played around with accounting for variation when modeling property appreciation (a simple metric that I started with).
