The most common way I see people misusing money is when they spend it mindless or on things that they don't truly value.

The washer is definitely from tenant misuse but unfortunately got included in the lease. 

If the diagnosis is unsuccessful but the professional determines the problem to be caused by tenant misuse/negligence, I bill the tenant for the service call.

That's dangerous.The most common and dangerous misuse of an appraisal is by the borrower for the purposes of satisfying an appraisal contingency in a purchase agreement.

If you own the lots, and you can get the house 60% built - meaning it is dried-in (correct my spelling or misuse of this term, as needed) - then you might be able to go a local hard money lender and do a cash out refi to finish the project. 

What is bothering me is that they are trying to misuse as were saying last time going to talk to their lawyers don’t know what for how to avoid paying rent ?

While the SBA.gov website does not explicitly state that it cannot be used to purchase investment property, the name of the loan program (Economic Injury Disaster Loan) suggests that it's to be used accordingly.The SBA PPP does note in the interim final rule that misuse of funds will be investigated, and if deemed as such, the entity will be fined.

Any misuse will put you in jail.  

I know it may be the desirable route to see which option you think will yield more cash, but if your business model is to buy and hold, then you're misusing your time trying to figure out how the wholesaling process works.I mean, personally, those three options are three different business models.

Another way to think about this co-mingling is what if this was a major corporation of a sort, if you had the company paying for your personal stuff that would something like embezzling or misuse of company funds.
