@Mike HernI bet you can go to your local grocery store and also find these types of deals like you can your favorite cereal.

If I select the forms on the BP website, it redirects me to the book store website. 

Again, the BiggerPockets store has some books on this topic, or you can learn about it by watching podcasts, reading blogs, and interacting on the forum.

I generally advise my clients to skip properties that are near main street traffic or commercial buildings/stores.

I guess you havent been to the grocery store in the last couple years , filled up your gas tank , paid your insurance , or bought a car  ? 

@Chris Jordison Check out the bigger pockets book store.

If you want to brush up on PML, I suggest you check out my book Lend to Live: Earn Hassle-free, Passive Income in Real Estate with Private Money Lending available on the BiggerPockets book store.

Make a folder to store relevant documents per property.

For example, I can get up-to-date pictures of a property (with time stamp on it) for as low as 10$ in 24 hours, most of the time it is more expensive to grab your car and go there in person if you also count your time invested. there is a great book called "long-distance real estate investing" by David Green (you can find it in BP book store or on Amazon) which goes over a lot of those services and find solutions to long distancing investing.

The retail (corner store) unit was converted to residential over 20 years ago.
