We have one rental with the same setup and the tenants appreciate the ability to store things down there (assuming it remains dry) but woudl not want to use it for anything else. 

Sadiy, in essence, we pay the unfortunates so they don't rob and murder us.All the people making believe it is okay to work without paying taxes, paying for licenses, insurance, payroll taxes, etc. in my book are GREEDY THIEVES and they are robbing and destroying the world around them.This subject raises another hair on the back of my neck and that is the subject about people not wanting illegal immigrants stealing our jobs, not paying taxes and getting billions of dollars in free medical, using our school systems, hospitals and people complain all the time, but those same greedy people use the illegals they hate to mow their lawns, doo 90% of the construction etc, and then it is okay to cheat on taxes, etc.I am not okay with double standards for the greed of money.

A sump pump would almost be mandatory, on top of dry locking and proper grading.This works great in college towns where renting by the bedroom is linear.

I positioned the door on the ground and then tilted it up into place for a "dry fit".

I am a roofer, painter, dry waller, jack of all trades self employed individual.

When you said "string a line for his clothes dyer" I assumed you meant an old fashion clothes line so he can dry his clothes
