An example of not recession resilient would be a karate studio or hair salon, things consumers cut back on when times are tough (and now you, the property owner, aren't getting rent, and thus might have challenges making your mortgage payment).

Let her keep paying the rent from the mother's estate if she needs to.

What you recommend me how to start investing in another property for rent.

Enjoy a $3,690 Market Value for Rents and potential $10k annual cash flow.

Property is stabilized but rents need to be increased for a few units.

They then cover any damage lack of rent payment.

So, I told her that she could rent it for $1200 as is.

I am undecided on whether to buy another property in west New York and continue to do airbnb or buy one in PA just for rent cash flow .

I have been living and renting the other. 

Few and far between.You can always find someone willing to collect rent for a fee.
