Folks who need to find a place NOW, need to find a place cheap, have been turned down by other landlords, or don't question the old saying "if it sounds too good to be true...." are often those most vulnerable to these scammers.Gail

As a seller (say you're doing a flip, or selling your own house), same, otherwise you're also vulnerable to the 'pie in the sky' agent who estimates high to get the listing.

Again, it gives them confidence, shows you are vulnerable, maybe even desperate to settle before you get screwed.

I don't want to put my family in a vulnerable financial position by obtaining a loan before having a full understanding of the financial landscape, costs, etc. of my future location. 

Then I'm vulnerable to lawsuits.

The only one with a major disadvantage is the unskilled operator going out of state ... not only do they not have the knowledge to optimize an investment strategy for the market conditions and this vulnerability shines like a big target on their forehead to the less scrupulous operators that can easily spot and take advantage of it, but they also have no means to learn or apply hands on control in order to execute such an optimal strategy.

If the eviction was due to misfortune, it's sad and it also means that they are even more vulnerable to future financial misfortune because it's tough to clear the problems they already had and stay ahead of rent.

I'm even interested in these 55 plus home parks as a long term living solution, though the space rents keep going up on these and they are vulnerable to development.

Or is this a liability issue (if a tenant were to fall and then sue me / IRA is that remaining money vulnerable?)
