Do you have personal experience with these?

It can be personally designed post cards or it can be letters. 

what kind of investment was/is this  a little more detail may protect others if you think this person is a financial predator.  

Left me feeling like a basically have a retail/fulfillment person on my team so I'm a big fan and would recommend giving them a shot, especially if you're in a similar position as I was: Needing to furnish an STR quickly and cost-efficiently. 

I am days/weeks away from trying it at my personal residence.  3500 sqft but only two people using it, so not sure how good of a test it will be. 

But I find from personal experience and from my buyers' Airbnb experience that it's a bit of a hassle trying to get guests to rebook at the new listing.I don't know how strict Joshue Tree is at enforcement, but in Denver and Colorado Springs here, you could probably get away with an STR listing for three months without the license.

If a property goes into foreclosure on a second, as Ken said you will either be buying it subject to the first mortgage - meaning it's your mortgage now - or the first has to be satisfied to take possession of the property - or the owner of the first is going to be there bidding what they are owed, so you would need to outbid them to get the property and then you are the person paying off the first mortgage. 

I also think most markets won't see anywhere close 6% cap rates (for single family homes which is what I personally invest in).The questions you get to ask are then:Is the extra 4% worth the hassle of management and lack of liquidity.   

I have been to a few of them personally its really something and the folks that own them are under the radar and make MILLIONS.

Just a good person too if you want to bounce any ideas off her.
