Have them pay a week or two before they arrive when they are past your cancellation period.

And I would love some passive income or at least someone to pay my mortgage until we can pay it off maybe.

Quote from @Shawn Questa: Hi all,I am curious what some of the Pros would do to Help a Seller in this situation while making a Deal happen.I found a 200+ day old MLS Listing where the Agent said the Seller is in Financial Ruin, hasn't Paid the Mortgage in a year, owes about 180k on an approx. 210k House and multiple Buyers have backed out.I don't know how someone could not Pay their Note in a year and not at least be in Pre-foreclosure. 

I also pay my mortgage for the house I live in.

Kody, you need to investigate the Pace Subto group and pay to get in. 

When they pay a non-refundable fee, the money is already gone. 

The interest rate isn't that huge of a difference between the 15 and 30 so worst case scenario if you have the 30 year option is you start paying it down on a 15 year timeline - sure you'll pay a little more in interest over the 15 years, but it will have been worth it if you bought another house.

In reality, you are going to be the one to pay for that.  

I noticed that the previous owner let them pay half the security deposit and the other half later, which is a red flag.

@Shayan SameerThe non-paying tenant could impact your short-term cash flow, so consider the potential costs and timeline of eviction in your state.
