(2) I heard that now asking tenant to move out, landlord has to proved one month's free rent? 

I have a lot more research and studying to do before jumping in however looking for a market to invest in is something that has been an issue for me. 

I would provide pictures from the home inspection that show/prove the before and after. 

I am an 18 year old studying Physical Therapy and playing football at a local d2 school where I live.

I guess you would also need to prove that each multifamily will get a certain rent.

Many local gov't will require a feasibility study, environmental surveys, storm water run off reports, etc... it varies from county to county, state to state, but be aware. 

From my studying, dropping nearly $70k for a property is not necessarily a good move, so what would be best in this situation? 

Can they prove how long it takes to rent a vacant property?

Fyi - Studies have revealed that the mind constantly wanders.

It will then be easier to prove the value on the day you moved out if you sell in the future. the time you lived there will be taxed exempt and the value created after that date will be taxed as a rental.
