Do you have a broker listing the property or are you only relying on craigslist ads?

I don't rely on the zestimate too heavily.

Michael, my feeling is that any valuation system that must only rely on subjective data can not be accurate in any area to the extent that it may be relied upon for investing purposes.If you were to appraise a property anywhere, then check some other source like Zillow and they were exactly the same, you'd need to test the probability of that happening again over many other samples before there would be and degree of certainty to bet my (or your) money on.

In real estate rehab, unless you are doing something novel (i.e. rehabbing with passivhaus components), you can probably can rely on conventional knowledge held by your trades for much of the detail.Coming from an IT software and infrastructure background, I found the execution more difficult to manage than I initially envisioned for the size of the projects.  

I honestly believe the reason I am not part of that crowd is because I am not lazy and rely on my brain not the emotion of making it big or going broke for that matter!

I know that I must always due my due diligence and not rely solely on information provided by a real estate agent; but some information is needed and/or has not been provided at all and this agent is working at a snails pace.   

I wouldn't use their algorithm solely to rely on a value of the property.

Otherwise, you can start learning alternative financing methods that don't rely on your personal credit availability.

The issue that the other party is relying on is the section is wrong.  

If I had to rely on separate groups or individuals for all of these pieces, the model would never work.
