Focus on absentee owners and start with the ones who live the farthest away and only own one property in the area since they have the least use for the property.You can also drive for dollars, looking for anomalies of disrepair and then look them up in the tax records and use a site like Spokeo to do cheap skip tracing.

Quote from @Hector Espinosa: Hi,I'm negotiating a seller financing deal which may be my first one and would like to ask for some advise about and what are advantages and disadvantages about seller financing deals.These are the seller financing terms:House Price: $330,000.00 USD​ (Sellers still owe ~$301,000 USD)Down Payment: 5% = $16,500 USD​Loan Amount: $313, 500​ (Monthly payments will be amortized as a 30 years loan​)Interest Rate: 4.531%Balloon Loan Term: 5 YearsMonthly Payment (P&I): $1,594.24​Closing Costs:  ~$3300 ​Zip Code: 74105Observations:       * HVAC requires an update but pending to inspection (replacing with a new one will cost ~$10,000 - $15,000 USD )     * Expected Rent Income: $2,000- $2,300 but this is has been really complicated to get a good estimate because is all over the place in the different sites I have checked

A fair warning, you'll be wading through complicated info.  

Joseph, the best method for you would probably be the MLS or sites like realtor.com etc.

I am aware of Crexi, Bizbuysell, and Loopnet and reach out when I see something for sale on those sites.

There are so many veterans who have carved nice paths in real estate investing all over the site and as guests on podcasts that you can learn from as well.

the "too complicated" part is the partnering. 

Any other major syndication site has restricted sold data so it will be incomplete.

we do have to remember and I know its 10 years ago and many on this site are post GFC investor and know no better.. but were do you think all these deals came from... back in 2010 to 2014  it was not from well performing assets it was from stressed and failed owners. 

I flew there and walked the house, looked pretty turnkey rental grade): $1029 GFCI outlets, downspouts and guards, drywall, paint, bathroom vent$4615 (new AC unit since unit was stolen before tenant moved in, didn't file insurance claim because didn't want my premium to go up) $600 (water line, gas line, P trap)$60 lawn mowing$112  thermostat repairMy opinion is that Class C is better for local investors who are on site and know how to do repairs and self manage.
