Make sure the Use Occupancy Permit is approved, and the prints on record match that permit.

Competitors- What are their rates and their occupancy?

They do exist, but those types of deals are usually snatched up by owner-occupants and they run the price up too high.

I know one guy here in the Denver area (very pricey..) who has done quite well as a "serial owner-occupant".

First thing I would recommend is buying a house or duplex you can move into as an owner occupant.

If you mean Houses of Multiple Occupancy as used by the British (in the states the term is usually MFR, Multiple Family Residence), then you have to define how you count 200.

I originally visited this property in February, made the offer within 30 days, but it was contingent on certain repairs and a new Certificate of Occupancy (hence the 6 months between offer and closing).  

Whenever a tenant has asked that I remove a person from the property they are renting (boyfriend, girlfriend, wife, cousin, illegal subletting roommate, etc) I simply tell them that I cannot remove specific people, if it's an issue I will remove ALL occupants.

@Tyler Divine It definitely depends on your market and your end buyer, but if you are talking about the average owner occupant in the median price range or lower, flashy is probably best.
