Do I run any risk of losing part or all of my investment?

One of our biggest keys to success is that our tenants have a lot to lose.

I graduated from college and got a business degree with emphasis in real estate and I got broker license in 1980.  

In Florida (I'm a Real Estate Attorney here) I see wholesalers costing themselves money because their Contract and assignments aren't done in their favor, or losing deals all together.

Hi all,When I bought my house roughly 2 years ago, the gentleman next door was explaining to me that he was on disability, however, his checks weren't coming in fast enough, and he was going to lose his house. 

Sorry on the delay folks unfortunately you win some and lose some the seller only gave me a week to close on the house and couldn't get everything together in time. 

Even though my degree was in business with emphasis in real estate I stayed in construction because I felt more comfortable with it.  

My broker told me that's deceptive practices and I can warn them to remove it before reporting to the state and cause them to lose their license.

I know there's a risk of "losing" one or both if there is too much of a delay, but since Person #1 made the appointment first, is there a best answer to this?  

If you fail to close you will lose your deposit (earnest money).In future make sure that your "C: Buyer has deposited money into escrow account prior to signing agreement (proof of funds) or shortly thereafter.Good Luck And Thanks for your service!!
