The tenant has expressed interest in purchasing the property.

I understand the concern to not offend and politically stay in the good graces of the seller but I hear this not wanting to offend concern a lot and I don't agree it should ever be initially a worry - unless the buyer has an expressively shown (based on previous behavior, past transaction experience, etc) they are hard or impossible to negotiate with. 

Expressed alternatively, home appreciation is lagging behind rent hikes. 

They still express interest in buying the house, but they won't qualify for a loan for the amount we are asking.

We have a couple of people that have expressed interest so we will see where that goes.

No warranty or guarantee is expressed or implied.

You're lucky they didn't just decide to evict everyone.Every State and Locale is different, but my leases all allow for guest to stay at least 15 days before needing express permission from me.

The next meeting is February 7, 2016 at the Panda Express (2580 Windy Hill Rd SE, Marietta, GA 30067) at 6pm. 

Hey Devin,When I was marketing to expireds I was sending a 3-step direct mail campaign.First step was a postcard letting them know I was going to be sending them a Home Seller's Guide (several other reasons for this postcard).Second step was the home seller's guide in a fax 'Rush Priority Express' envelope, along with a sales letter and testimonials from Angie's List and Zillow (screen shot).Third step was a mini trash can with a final sales letters ("Don't Throw Away...").Separates you from the bunch, plus it gets you to follow up because most agents just send one thing in the mail, or just call once, and then never do any follow up ever again.

Just expressing my own thoughts, based on what I've heard over and over again...
