I've collected over 90% of all possible income the past three years, and my occupancy rate is just under 4 years.  

For example out of the 23 units occupancy has averaged 90% for the last 3 years and 80% of tenants are the same from 3 years ago so only 20% turnover.Payment history will be important and structure of the leases for penalties if late.

(I know hoping for appreciation is a no-no)Rent out the spare bedrooms to friends or anyone I can find that is suitable to rent to.Once the 1 year requirement of occupancy comes up, put the home on the market for a reasonable profit.Or decide to rent the home out, in my town rentals that are updated can rent for $1500 easily, all the way to $1800 a month which would result in 500-800 cashflow. 

@Neil Aggarwal Hey, I have a deal, nice 12 unit spot, $120,000, assume that is full market value, cap rate is pencils out to 11.5%, walking distance to the university, nice area, Seller will carry a second at 35% for me, you interested in taking the first at 65% LTV with 12% ROI and a 49% equity position, I won't have a dime in it, but will do the deal and manage it, If you want out after a year I'll take you out and payoff your first (I'll have your note purchased at par at the UPB) I can guarantee occupancy for 5 years, will add lipstick to it over the term with my cut and we will sell in 2020.

Unfortunately, the rental condo unit that I own is within a complex that has fallen below 50% owner occupancy.

I look for specially the population trends, median income, percentage below poverty line, break up by age, school districts, access to public transportation, I also look for the breakup of the population by job or occupation for the zip code, that gives an idea if it would be a good place for my targeted renters.

For example, if you repair the HVAC during your occupancy, you will not receive a tax deduction for it at the end of year as it is not a business expense.  

That should be enough of a down payment for most owner occupant loans. 

Your state may not allow this based on the size of the project and the occupancy.

There will be an initial "first look" period for owner occupants only, 2-4 weeks.
