5 day should be first then the lease is officially broken by tenants, then you can negotiate a new lease new rate including the second tenant if approved.

I am sure each branch of active duty has this official position, but I do not know what they are called in other branches.

Even if you have to pay for it, it should be looked at by an official, maybe with the subject city inspector or a referral from someone you trust about the environmental question.  

If the landlord gave you documents (including the estoppel) than you may be able to do something if this what you find when you officially start collecting.  

I'm 20 years old officially today, and have been thinking heavily about renting out properties for the last two years.

I currently do not hold my CPA and I am not giving you official tax advice but..You live in the state with THE HIGHEST state income tax but want to buy in a state with no income tax that gets their tax money through property tax (the 4th highest in property tax).

Even though they weren't officially on the lease, in that particular state/county, they couldn't be shut out.

It really sounds like you broke the lease by renting the property before the official lease term was up even though she wasn't living there. 

deals that been closed and registered in the country/city official records?

So far none of the incentives have gotten officially approved because they are still secret.Everyone needs to start watching the postings of the public meeting agendas.
