For example create a mileage tracker, rent collection form, maintenance requests, tenant communication, expenses, etc.

As investors, we are always looking at how we can modify, tweak or change what we are currently doing to become more efficient and profitable.  

I make sure my policy is communicated as much as possible and on every property to prevent discrimination issues.If the tenant applies and does not meet the requirement I just tell them exactly that.  

Original single pane windows with hardwood frames and custom wooden storms outfitted with spring bronze are equally as efficient as double pane vinyl inserts and completely worth saving because they will last 200 years instead of 20.

This shouldn't be taken as not having the right to communicate with them, I'd say your lender needs to grow some hair.

Square footage, efficiency of furnace, insulation, and windows will all play into how much gas you will use.

Communicate with them and document their financial status.

Call it a script or call it preparation, but I see it as essential preparation for communicating with prospects.Here is an old realtor "for sale by owner" script that has done me very well over the years.

His company never has the funding for COE.......and then they won't refund your money, much less communicate with you.

For us, one of the big things we're starting to do is make the homes very energy efficient.
