I either met or spoke with them about the property I was interested in and they assured me that it could be rented at the price I wanted.

Do not sign a lease with them until they are in compliance with your rules.  

This amendment, he assured me, would exclude the containers within the contract itself and therefore protect my continued possession of them.Now, with the amendment to the signed contract in hand, the buyer has yet to respond to the amendment and it has been so long now that the closing date (that was such a worry in the first place) on the original contract is past.So, since the amendment has no deadline for acceptance or denial, how long am I supposed to wait?

My understanding is that the year of construction defines the code compliance unless the job requires permit (addition, kitchen, etc).

I would have a very strict pet addendum, and visit the property periodically to check on the tenant's compliance with it. 

@Jeff Filali Title co was Assurance abstract.

So back to seller financing, how can I assure the seller that the house does not get cashed out or re-financed which would then mean the seller got that big chunk of change anyways.

Apparently it's a compulsory and mandatory fee which will be used for the loan processing before the final disbursement of funds into clients account as its calculated.When I asked if paying $3,600 will guarantee my loan, I was told this: I assure you that you will definitely be approved for the loan.

@Brian HalsteadWhat you are proposing actually creates IRS compliance risk.IRS rules prohibit any kind if direct or indirect benefit between the IRA account holder and the IRA. 

They followed up with him after their lease officially ended, and were assured that they would get their security deposit back within the correct time period (in Georgia, it must be returned within one month of vacating).
