In the lease you simply identify the portion of the property the tenant is able to use, including language that they can request use of the yard for a special event. 

The lender language just states "I intend to occupy the home for at least part of the year for the first year."

I will be officially stepping into FULL TIME REALTOR STATUS at the end of this school year (I have been teaching for 9 years) and am scared out of my mind to give up my W2 career.

Make sure all agreements are in writing with sufficient language covering all points and outlining all what-ifs should a breach occur. 

It's not uncommon for bedrooms to have been added onto over the past 60+ years of a home but not to have been 1.permitted or 2.known to the tax officials (related to 1 and more common if it is a rear addition). 

I ask because I listened to the BP real estate podcast #300 yesterday and a gentleman, who I believe was an oncologist, said that you should have read enough before approaching a 'mentor' to show that you have enough commitment to learn the language and the general terrain that you have skin in the game and are not just looking to get rich quick.

If a unit is fully ready and I already have a tenant lined up, I will allow them to start moving in a few days before the official lease date without any extra cost (assuming I have the security deposit and first month's rent, in full).Now that I'm thinking about it, I do a lot of freebie gifting!

Are we all speaking the same language?  

If the discrepancy is enough to kill or materially change the deal, then it is time to start digging into the contract language and seeing what your recourse to walk away from the deal based on this revelation.

In many cases I have heard of family and friends being a newbies first investor but everything needs to be laid out in clear language with the risks known.
