I like Jd Martin's comment about the credit score.You may also want to consider these criterias as well:--insufficient Credit and Rental Requirements could be assessed an additional security deposit equal to 100% of the stated rental amount, over and above any other security deposit or additional security deposit required.

Of course you could find extremely motivated sellers who either require negotiating a short sale of some sort or just with insufficient profit in the property.

Don't know the terms of the offer or if an agent was engaged in the transaction, but this is a case where DIY fails due to insufficient understanding.The offer should have NOT been on a standard residential form, but used a Commercial Property FormThat form gives the opportunity to require the seller [x]  To deliver the property vacant.OR on the standard form, to add that contingency Without that, the BUYER is required (in Calif at least) to perform a NO Fault Eviction and that means relocation fees will be awarded to the tenant.I fear this was a DIY purchase and you're on the hook for the consequences.

They send me a check for half of the rent on January 1st for me to deposit right away, and asked me to wait until the 18th to deposit the second check as they had insufficient money in their account.

In the event that the 16.5% means you have insufficient PITI reserves that the lender will require, you will be forced to use a hard money lender at 10%+ and now your cash flow situation will be all jacked up.

As a result I have had a life long interest in learning about nutrition and maintaining health.

I passed, on the property, because there would be insufficient equity built up to refinance and satisfy the balloon note.

What was there was insufficient.  

So, if ANY of the members of BP ever have any questions regarding health / dieting / exercise / training / nutrition, please feel free to reach out.

I believe there have even been causes in CA where an option (with consideration) was still deemed insufficient to convey equitable interest.
