I'm not sure what that says about success rate, but success overall looks pretty good to me.I guess if there's any "entrance exam" it's your own response to the initial presentation of the education as a gateway to your own REI business and as a marketing opportunity for those who choose to pursue it as such.

What are the best doors to put in crawl space entrances?

Have your HVAC person do an efficiency test on the building looking for air leaks and Temperature hot/cold spots.Does your entrance have a Foyer area and second doorway.

An entrance contract would help you if you have a mentor or coach to help you as well if that is a choice for you. 

It's one of the "entrance/exit" strategies I use...and teach.

This home features a sunroom and your own private entrance and rents for $500 a month.

The entrance to the attic is a pull down hatch with a fold-up ladder.

When I gave him his notice to quit (noncompliance with rental agreement and tenant to maintain dwelling unit) and did the re-inspection 23 days later with an actual pest inspector, it was discovered he had essentially moved the whole kitchen/breakfast nook mess to his room and now his room is also a health and fire hazard as well because one of his entrances is blocked by his hoarding.My question is, based on your experiences and what you've read or heard, is it any easier or harder to evict someone for anything other than pay issues?

It even has a side entrance that leads directly upstairs. 

Each section of the house has its own entrance, kitchen, laundry, etc.
