Also, you won’t find a long term rental with a 10% down loan that isn’t going to be cash flow negative with todays rates and property values, especially if you’re not self managing.2) STR will net more but to do a great STR, you need to put the cash into the property to make it a top listing.

Chances are, if a killer deal is listed on the market, it's likely already under contract.

And then you can't see other listing from other agents?  

Initially, my family and I lived in this house for a couple years before deciding to rent it out, anticipating a market recovery from the 2008-2012ish recession.

Access all details of listings in MLS, specifically disclosures (MLS access)2.

How much do you usually make an offer below the listed price?

On Zillow they show who the listing agent is.

Keep in mind, you can only host open houses for listings within your brokerage. and if you go to other agent's open houses and start soliciting the patrons for business, the agent/host will not take kindly to it :)
