How I do it is through selective screening and I have been 100% successful.By instituting certain screening standards it will naturally eliminate the vast majority of non target applicants.For example young couples with children will generally have lower credit scores. 

If your agent knows the general nature of what you're doing as you explained it here, I would question them not informing you of that!

Naturally I had to do a double-take to make sure I heard correctly, as you never think something like this would actually happen to you. 

I use the BiggerPockets tools to analyze properties a few times a week, but I feel that I might need to start looking for foreclosures, bankruptcies, or something of that nature as the price for the homes in my area on the MLS are listed way above what would result in decent cash flow given.

Before we start the development, we have some digging to do and I was wondering if anyone knows who we should approach about finding if there is natural gas, sand or coquina underground. 

I understand the concept of making a tenant responsible for small repairs but tenants in nature live paycheck to paycheck mostly so it likely won't get fixed. 

Otherwise, you will simply have to wait for the market to naturally appreciate, or for you to pay down the loan. 

I have special provisions regarding the nature of the business in the current lease, but am looking for more ideas for protection/usefullness to tenants..

This is due to a special rule under Revenue Procedure 2002-69 that states that a LLC owned by a husband and wife in a community property state is also considered to be a disregarded entity and for tax purposes, the property is treated as if it is owned directly by you and your spouse.

As the others said, I would make sure you have policies and procedures laid out for early lease terminations (i.e. termination fee, sublease required, etc.).
