For example, you could start with something like" Dear xxx Thank you for your interest in the single family house that I'm renting at xxx.

This letter is to inform you that as of Friday February 27th XXX LLC has purchased this property.

Homes sell so fast that many offers are over asking not under asking price.I have had in the past many clients who wanted me to call the listing agent or the owner in some cases for unlisted property and ask "would you take $xxx. and carry the financing".  

Best to call me at xxx-xxx-xxxx' a thousand times over the past 10 years. 

I will need some flexibility in scheduling as we have a move in date of XXX".

The only information recorded on the deed is that the owned is xxx trust with yyy as trustee.

I would suggest doing a short addendum stating that they will return the garden area to it's original condition if they move out, otherwise there will be a $xxx refurb fee to restore it.

"is it above xxx?"

I'd just send them the required notice and tell them their new rent is $XXX.

This house offers convenient access to XXX University (10 mins), XXX Hospital (5 mins) and lots of shopping including Costco, Bed Bath & Beyond, Petsmart, Kroger & more just minutes away.
