Inquiries, expedient responses for assistance, repairs, and maintenance, frequent rate/yield analysis, etc. 

That being said I am a big fan of being strict to a criteria.

Making more income requires a significant amount of time, stress, and energy which would come at the expense of my family.I've also gotten to the point where it's harder to delay gratification--it's not a skill my wife is great at (so delaying gratification frequently means I go without, and she doesn't) and spending $2000 to go see nephews and nieces is much more important than having an extra 5 shares of google or MSFT. 

If you can, go several times, so you can watch it happen from the foundation all the way up.If you live close to a store like Home Depot or Lowe's, sometimes they have free classes on "how to install a ceiling fan" or "how to paint". 

I talk about this on the BP podcast I did and frequently on BP. 

For 20 years we have dealt with space heaters (of various types) for heating the room in the cold OH winters, or just ceiling fans for cooling in the summer.

b) That all my records are available online, and emailed to me monthly.c) Frequent inspections.d) A preformatted Schedule-E helper report which gives me everything that my CPA needs to file my taxes. 

But I take out the dish washers, the washer and dryer, all ceiling fans (switch to dome lights) and garbage disposals.

I have 3 covered 'Mare Motels' with water, lights, fans and misters, plus a Riding Arena.

I love ceiling fans.
