There is a better chance that they either inherited the property or are a landlord that might not want the home anylonger.

So when you have doctors making babies with lawyers, chances are their baby will succeed in school.

As they say, you never get a 2nd chance to make a 1st impression!

After much thought I gave a very young couple a chance, only because I thought it would be great to only have my house vacant for 3 days vs waiting longer and finding better renters. 

The lender is ready to foreclose now that the market has recovered and they have a better chance of recovering all even though they are in a 2nd lien position.They'd like to stay in the house, but the sad truth is they cannot afford that house any longer (and neither can your unemployed friend).  

(you will come a cross a lot more confident in your offers or just talking to sellers when you have at least two more nearly as good deals to make) The above action will dramatically increase your chances to be able to negotiate much more realistic deals for you that you will be able to perform (close) on. 

I currently am unemployed, my age is 18 and in college completing classes that will further my chances into becoming a successful individual in the real estate market.
