I graduated from college with a business degree that É phished real estate and I got a broker license in 1980.  

Now, here is my take on what could be happening just from reading your post:If you are making any type of E-Mail/Written communication with these people, you should do yourself a favor and run everything through Microsoft Word and use spellcheck. 

E-Lights will be $60-120 or so a piece plus install.

Type out an "investor sheet" with basic info ie: Name, number, e-mail, area, price range, types of real estate (rent, fix & flip, multi-family etc), how much rehab is ok, and misc notes.  

E-mail?

I H-A-T-E filling out the same 30 pieces of crap every time (could be a couple times a day) I make an offer. 

I'm currently pursuing my R/E license and a total rookie to real estate investing.

I'm drafting an e-mail to my tenant to make sure he understands what's involved here.  

Coincidentally, the day after I posted this, Dave Van Horn from PPR sent out an e-zine article discussing asset protection in RE considering LLCs, trusts, etc, and while catching up on NoteMBA podcasts on the same day, they discussed investing in notes in an LLC vs DBA. 

After starting to listen to the E-Myth and wanting to phase out of the DIY portion of my business, I'm trying to get every system down so I won't be physically doing anything as the "technician" (E-Myth reference).
