Here is how I approach it-Same type of property, bedrooms, bath, etc (if I can find similar houses)I try to keep the Comp properties in the same school districtI go back 3 months to start (the market is different now than it was 6 months or a year ago)Then I account for upgrades, market temperature, etc.That gives me a range- if I feel the property should be higher than average I need to be able to justify that because properties are sold twice- once to the buyer and once to the appraiser

That is what they make their offers based off of, not just blind low balling to try and get a better deal.

Are his files organized in one of those rotating lottery ball machines, crumpled up?

Average of about $600 rent per month.I sent a low ball offer not really sure if it would be accepted, but to my surprise it was. 

HelloI'm trying to urgently put together a comparison and a temperature check for the average 25-year mortgage rates available in the SF Bay Area.

I would talk to @Lloyd Ball.

Learning from my mistakes it has taken me a little longer to get the ball rolling than I wanted.

We are almost ready to move onto our next investment either by selling thi house and doing the live in flip again, or by finding enough money (hard) to buy a rental and get that ball rolling.

I've got a curve ball in insurance on a property that was built 100+ years ago.  

I'm considering making a low ball offer.
