I think the sites and their estimates are pretty impressive considering they contain virtually every home in America, often with interior pics, but they are what they are: free tools that used automated formulas to predict something that can often be a bit unpredictable and can't fully account for the human emotional factor (for example I bet something like the Brady Bunch house zestimated far less than than its actual value)

I understand location and bed count are the two most important factors and I should find similar properties when estimating, but do you have a specific strategy when making a purchase?

For the sake of these calculations, and simplicity, I did not factor in changes in insurance, taxes, maintenance, etc.

I would imagine you have employees and systems in place to help reduce these factors but what has the outcome been so far?

The cost of the lot will obviously be a major factor.

This could mean different things to different people and I think certain factors affect whether or not something is a good deal or not, experience (a good deal for a newbie is different to seasoned investor), location ( a good deal in California could be a horrible deal in Indiana), strategy ( a deal could be bad for a flip, but really good for a rental), skillset ( someone who is handy can save more money on labor opposed to someone that doesn't know anything about handy work, also someone that can manage properties opposed to someone who isn't cut out for it, etc).

There are several factors, my underwriting minimum is $200/door per month cash flow.

Hey Patrice, there are many factors to consider and unfortunately there's no easy answer that anyone here can give you.

If they discounted the price to factor in the age of the roof, you will have less wiggle room. 

Which is cheaper to close is also a factor.
