@Steve Babiak The link may be helpful to the OP if he was curious- thanks.

Now, to answer the OP's question; If I am playing with some other person's money, I would focus 100% of my time and energy on burning and turning that cash.

Back to the op comments, most here are not trying to swindle old people in 2nd-3rd world countries or anybody for that matter!

I understand the diversification argument however in the OP case, they already own a rental in Vegas so they would be diversifying by buying a rental around their home.

My tenant told me that it's very annoying, but they soon got used to it.I think the OP would have a very difficult time renting the house if every potential tenant knew there was a sex offender accross the street.

Using an online calculator will reveal that price to be way out of reach.Also, going to a lender will lead to a similar estimate unless OP seeks a mortgage pre-approval which could lead to a hard pull on her credit. 

@James Woodrich in your OP at $100/door with leverage (75%) and a purchase price of $2.4mm as suggested, you would have a 20% annual cash on cash.
