Eventually those will either go back to the bank or they will find out that losing 5 to 10k at once is the reality (better to take a shot in the head then one in the stomach).  

Personally, I don't lose sleep over sized of earnest money deposits when I'm the seller.  

My biggest concern with people who buy all cash are those that literally spend ALL their cash and lose their cushion when it comes time to deal with major repairs, increased vacancy, job loss or prolonged illness. 

But i'd hate to do that because I feel like there is a disconnect there and I either wouldn't learn from the experience and/or I would overlook something and lose out on some of the return or worse actually be in the red and lose money.  

never put houses in ur personal name and never personal guarantee debt, and u cant lose.....

I believe when you try to hit ten major goals in one year it tends to make you lose focus on all of them and none of them get accomplished. 

Mobiles lose value over time vs house .I am sure you could cut your teeth on a mobile home as a rental but  will not go up value.Study up on the topic see what the numbers are there are many ways to make money ,then stash the cash move up to a house !

But that would require you to, you know, lose money somehow.These lines are gray.

But if they lose their job, they have to.

My advice, even though you didn't ask for it (since you are on a Real Estate investing forum) is to sell the car and hope you don't lose money but even if you lose a little still sell it.
