I'm looking to buy my first duplex late Spring as an owner occupant in one unit. 

The unit that i had sold had a certificate of occupancy from the city.

Instead, buy the house using Seller Financing and have a six to nine months (you decide) promissory note to seller that's due on sale (i.e. after rehab sale to owner occupant) and give them say $120,000. 

 :)It's very complicated to buy for cash, rent to own, after a bit sell to the occupant on a seller financed note.  

I would double check the occupancy rules from the mortgage co.

Lenders will look at occupancy rate, cash flow, appraisal etc.  

, it doesn't seem that you have any GROUNDS to file for eviction until they dare past due on the September rent, unless you want to kick them out based on some other lease violation, such as "failure to keep the place in reasonable condition" or "too many occupants" or something which, it sounds )and looks) like you could probably do right away.

Kleisch are currently approved for financing through Greenwood State Bank in Evansville WI.The creation and building of Business Credit is also a priority.Seller Financing of 5%-100% will be utilized when available and if the terms are acceptable, in addition to other creative financing options.Private Investors:Private Investor funds will be utilized as necessary.The Kleisch’s currently have $20,000 available from a HELOC (Home Equity Line Of Credit) to use as necessary.Repair costs required prior to occupancy will be funded by one of the resources above.Private Investor Funding InformationGeneral Information: Funds will be held by a Title Company and withdrawals can only be made with the Private Investors approval.

Just staring out but the goal is to make property investment my full time occupation.

If you enjoy it and are a good person, you will succeed and build a good name for yourself regardless of your occupation.The occupation of a realtor/agent could become obsolete with the information age that we are in.
