If you only work part-time, you won't get full-time results.My advice is to pretend that everyone you are working with is you. 

Pretend you were them. 

A few ideas....check social media (LinkedIn, Facebook, etc); Google search the tenant’s name (I once found an ex-tenant I was trying to serve with papers who was listed on an online professional membership roster with her work info); reverse Google search the phone number; have someone else call the number and pretend to be a customer, vendor or whatever is appropriate depending on the type of business. 

Now pretend that loan officer, if he doesn't like you, can take your loan away in 12 months, or change the terms of the loan after 12 months, if he doesn't think you are cooperative or have an attitude, etc.You are not on equal footing with your tenants in the friendly, neighborly sense.  

@J PaigeI would send a letter return receipt requested from the post office today to establish proof that you are trying to clear up the issue because it will become handy if you wind up in court, and because people who know better know once something is sent return receipt that can't pretend it never got received.

Lets pretend she is telling the truth.

I have no problem calling an employer to verify- but I want to ensure its not someone on the phone pretending to be an employer.Just trying to cover all my bases..as i have met some characters.Thanks-Jenn

The point is you have a way to get the rent and to pretend you didn't is lying and that will not go well in court, but do what you want.

But, it's definitely illegal to pretend you own something you don't, then charge someone to use it. 

Most of these matters involving their tenancy can easily be handled much more efficiently and emotionlesswith short hand-written memos.In order to say the right thing – it helps to pretend you are the tenant receiving the memo!
