Home is located in a VERY HOT Market place.

The test was conducted by a certified person in Philadelphia.

There are some that will post on the Bigger Pockets market place but you'll find tons of them on Facebook.  

I would say at minimum you need your lease, your 3day notice letter, mail receipts, pictures, etc, also perhaps a copy of your bank statement where you show they paid rent, then didn't.Get busy with this....if they can't pay $900 or whatever this month, no way they can probably pay $1800 next month or $2700 in month 3.One thing that might save you time.....mail, certify mail, and hand deliver your 3 day notice. 

I am thinking about sending a carefully worded certified letter as my first attempt to contact them.  

IF Carlisle is not warrantying the roof (you said they denied the leak claim) then... as you said, WHY does it matter if you go with a Certified Roofer then!?

We are a nationwide marketplace that provides access to multiple TK investment opportunities, many of which are new construction.

IMHO its a all of the above times, post cards, door knocking, SMS, face book PPC and ads in marketplace... 

After the market crashed in 2008 we went on a buying spree from about 2009 until 2015/6 (buy & hold) until the numbers didn't make as much sense as the prices started creeping up again, rent prices were flat and many competitors started entering the marketplace.  

Is the marketplace still available?
