And I've cold called the owners of a few with no luck so far. 

About to get cold feet.

Seller looking to cancel a contract Hi All I entered a contract to sell a house in New Jersey there is a tenant with first right of refusal and we are waiting for his response to buy or waive his right, I got cold feet on selling all together and looking to cancel the contract can I in this stage still do so,Any response will help.Thanks.

The two most likely culprits: lack of bathroom ventilation or general window condensation during extremely cold temperatures.

Your Best opportunity is to cold call or door knock on property that appear distressed.

I noticed on youtube that people are suggesting cold calling leads to find deals. i have experience with cold calling in other things, but absolutely hate doing it and i know most people who get solicited calls hate it too. anyway around this?

If I did cold calling or driving for dollars like you guys I would have been dead a long time ago!

Running hot water will make it very easy to find and trace the hot pipes and if the cold ones aren't running directly next to the hot, you may be able to spot where they are with the camera as well.

These are also available at Walmart, etc. and act to keep heat from leaving windows.2) Caulking around windows and doors to help seal the air in.3) Putting plastic sheeting over louvered windows that won't crank shut, to at least restrict outside cold air flow.

You can try cold calling/farming off market deals.
