Does look a little too good to be true, but worth following up on.

@Aaron K. mentioned messing up your credit which can be true with bank financing. 

I like the true RV camper parks (for tourist and not local low life). 

Gross rent - 30% (for vacancy, maint, and capex) - PITI (principal, interest, taxes, and insurance on a 15 year note) = true average cash flow. 

After all, you two are the true principal parties in the deal. 

Obviously, neither one is exactly true. 

True financial hardship I understand.How is that any different from a yuppie living in the big city, renting a nice apartment and then worrying about the virus, decides to stay with Mom and Dad for a few months?

It is true that you could not evict her right now, but that is not going to last, and if she's a great tenant I highly doubt she wants an eviction on her record. 

You don't get the true benefits of owning RE, such as writing off the mortgage loan interest, which is a lot in the first few years.

Is that true?
