The issue that you have OP is that when you apply an equal interest amount to each period the interest rate is no longer 4%.  

mike S was asking about a tax deed sale, unlike the OP who was a bit confused on what rights a certificate gives you.  

Good news for the OP is that Del Valle is a good place to own land.

Also, I read where there was a guy working in one of the co ops in L.A. and even though they were doing it according to the laws in California, the feds swooped in, arrested him, and the man is now doing 3 years in prison.

In other words, posts are for the readers of threads as much as they are for the original poster (OP).

Good for you Jay, not sure what relevance this has to my OP though

Also, the OP should know that there could be a database of spills and it could hurt the ability to get financing in the future.  

Then modify the Op Agreement and add partner names/ownership.

I was confused because I thought you were saying it's just an ethics violation for the agent to not present the offer like the OP suspects is happening :)

Lol the OP says he's planning on living in the garage, making it a pretty good bet he won't spend the money to incorporate.
