If not, I'd make 100% certain that estimated rent is accurate.The lack of down payment, the interest rate, and the term of the note make me highly suspicious.

The question I have is this - I have checked with contractors for ballpark estimates.

when calculating the ARV of a single family, i know that I'm supposed to look up houses that have sold within the last 90 days or so within the same neighborhood, and no more or less than 200sqft. when doing so, REDFIN and ZILLOW's given estimates don't match each other and don't match the last sold price. what do you do to most accurately calculate ARV?

AirDNA is notoriously bullish on their property estimates.

Our worst one I'd estimate cost me about $3,000, on top  of double security deposit-- wanna get money from a person without a job? 

On the 1st property we purchased for $135,000 6 years ago at 5% interest we now have a mortgage on that home for $110,000 it is now estimated to appraise at $200,000 to $220,000.

Using rough estimates I bet that would get you to your $4500/ month free cash flow number.

I’ve done my best to research and draft up estimates, but figured I might as well turn to the Bigger Pockets community to see what advice could be had.Mahalo for your time and thoughts!

Our suburban house, appraised last year at $230,000, now has a Zillow estimate of $372,000.

I'm looking for rough estimations through this form to hopefully crowdsource reasonable estimates for an average 2 - 4 unit multifamily.
