I have prospective tenant who has signed a lease but hasn't sent deposit yet.  I made the mistake of also signing lease and sending back to them before getting deposit (won't make this mistake again!)I now have someon...

The tenant had asked prior to its official repair for prorated rent during the period the issue was being fixed.

Does an official partnership agreement supersede everything previously mentioned ?

I would find a JV form on here and agree to terms and then spend a few hundered dollars getting a lawyer to do make it official and legal for your state.

Apple also announced plans to add 20,000 US jobs.

My bigger concern is that he is asking for the rent/deposit before providing an official move in date. 

This is because this "new" address isn't on the official state filing.How the heck is someone supposed to start a business, and enter into contracts with a utility company or customers without first having a bank account? 

We went into contract officially last night and will request that info.   

I am excited to officially begin my journey in real estate investing in a few weeks and have made up my mind to stick this thing out and try and learn until it works.

I mean people with enough resources to make them workable but every single time I tell them the official process to make them work, they back out.In short, if you want to do one, you'll need to build two.
