My plan is to find deals that could survive a potential drop in the market and increase in vacancy.

My good buddy from college wasn't so lucky, he got jumped by a Grizz out fishing one day on the Russian River, didn't have time to draw and the bear chewed his face off (he survived just barely but lost his eyesight, sense of smell, entire face and part of skull, spent a year in the hospital undergoing many surgeries, etc.).  

You live there and seem to be surviving so what makes you think they can't hack it?

You need cash to get in and reserve funds to survive.  

Few survive past 10.Combine all of these factors are a huge risk.

Can this model survive if salaries are cut 20-30%? 

It helped me get up in the mornings and get what I needed to do done to help my family survive. 

Some of the surviving spouses will want to stay, some will want to move.

At the Knoxville Real Estate Investors people are encouraged to share what went wrong with a deal and how they survived the problems.

But there are parks out there still surviving and thriving on clay tile.
