Estimating After Repair Value...

This is not for wholesaling… this is for my future as a flipper and also the house I’m wanting to purchase to live in and flip in the near future…

What is the most accurate way to determine ARV?

Google tells me to find comparable sales? And that if I don’t have access to the MLS, then my best bet is to use the outdated Zillow and Trulia…

There must be a better way. What methods do you use?

Here is a house that I’m interested in determining the ARV of.

Here’s it’s page on the property appraiser…

I’m assuming that it’s market value is before repairs. Is this correct?

On a related note, how much can home prices change in the 2-3 months that it takes to rehab a house? A dip in the economy and one bad “flip” would be utterly disastrous to someone, such as myself, who does not have the financial resources to weather such a storm.
