I guess I understand the theory behind this concept, but I'm not sure how to physically put the plan into action. 

Yes you can as long as you have a deposit and your lease states the deposit can be forefit for damage to the property. 

I've got a unit (townhouse) that has sustained some water damage as a result of contractor error when replacing the roof. 

The water heater goes out and costs $800 to replace (eight months of income) or a bad tenant causes $2,000 in damages and forces a month of vacancy.

its just stupid what value does she really do, its branding and apparently alot, but she is smarter and alot richer than me so I should take notes from her.IF you know a good way to make money in 2020 that is duplicatable, sustainable, built over time, fits in a financially and physically ability that is a good blue ocean strategy, do tell! 

We know the risk associated with not being able to physically see the property and the work being done - so our proprietary soft-ware allows you to remotely manage your project from anywhere in the world with real-time updates and direct communication to your project's team.Regardless of your market, starting with a realtor in the investment industry will boost your chances of being connected to the right people to start making things happen.

You also have a rentor with tenant damage and the need to spruce up for a sale later.  

Of course, any damages that are caused by me or the guests will be paid for by me.

That does not mean she cannot be charged for any and all damage as it occurs on the property.

I have an experienced attorney but I have a sinking feeling I will never get the tenant to pay legal costs or for any damage.
