Then I'd buy some properties in growing areas that fit your risk profile with as little or as much down to make it flat to intrinsic(DSCR 1.0 to 1.25) via MLS or distressed and fix up(time consumption being a factor) and go deeper into these areas than wider in your reach.

I have put myself on Flat MLS but definitely always used Zillow.

If they did, that is not a "mistake" but flat out fraud and I would evict immediately. 

It's a shame when someone falls flat on their face, "forgets" to pay the IRS and then needs to search for money and scape goats and starts to point fingers but it's part of the lovely open forums and social media we all have access to so do your own due diligence.  

If you're going with direct mailings, you'll need to shell out for single page flat mailers. 

All these Berkeley/Oaklad/Hayward/Pleasanton has different price range when house is located in flat land and when it's located in the hill.

I’ve expanded my sources of leads, but that’s a longer term project as when we establish new sources we become swamped with submissions of deals bearing no relation to our published criteria; at risk levels a river boat gambler wouldn’t touch, or flat out the source just shotgunning whatever crap comes across his desk, without even reading the documentation.  

I expect the property to appraise for 300k after renovations.After renovations, I plan to find a roommate and rent one room for $800 a month and split utilities or $900 flat.

@Kenneth Bell I am in land development in South Florida, happy to connect with you! 

I charge a flat $150 pet fee.
