State laws set unlawful detainer laws but policy is dictated at the very local level. 

I'm not addressing cash flow here, because that's deal specific and investor specific.But here is a little tour of a "Typical (San Antonio)" (C minus) neighborhood with typical (C minus) structures I picked in a random neighborhood on Google drive around view.What (to me) makes a (C minus) area (in San Antonio) is an abundance of, Loose dogs in the street, fenced front yards with fences leaning and in disrepair, yards full of all sorts of debris (because the little houses lack storage space), antique (who knows how old) paint, neglected leaning secondary structures in disrepair, car repairs going on but seemingly abandoned, pickup trucks from the Carter Administration to the early 90's, Residents who WORK for a living, No chain of Murders, No Sal-mon in the fish tacos in neighborhood restaurants, decent nice (helpful) people you can talk to, extended families living close to each other who help each other, not unlawful in their ways.

Some of us feel very strongly about our "technique" because it's either made us very successful or we have seen others get burned by doing it differently. 

This is not a technique that you see anyone doing unless its the person buying meaning I dont know if any property providers offering this up anywhere. 

I've only been looking online with Zillow, and am wondering what other websites, tips, or techniques people have or use when searching for properties to ensure they are finding everything that's out there, or hearing about new properties that come on the market quickly. 

I wish more people would use their primary home as an investment property later - it's one of the best techniques out there.Now, to help with some things:1.

Paying too much initially can significantly impact overall returns, emphasizing the need for thorough due diligence and possibly more stringent financial analysis before purchasing.For future investments, consider leveraging local market knowledge further and refining your property evaluation techniques.

Looking to see what others do to market their own rentals/properties.

@Brittany Thompson  in terms of learning and applying techniques to wholesale property I agree with @Dave Savage.

She's still in violation of the rules and the intent of the rules; her only "trick" is making it harder to discover.I don't believe in building wealth by cheating and I wouldn't recommend her technique.
