We have a high base of tenants versus owner occupants!

The great advantage of house hacking is that you purchase the property as an owner-occupant.

Ideally, I'd like to find one with half occupancy for new tenants or one with a lease that is nearly up with a legacy tenant to make a move for me to enter.

I would love advice and tips on what’s a necessity prior to my purchase.Things like how much “blow” money should I have if I face evictions or have hidden repairs that may come up, should I see an accountant that specializes in working with real estate investors prior to my purchase, would it be smart to buy a property that already has occupants, etc..??

If its a big lake or park, you might look at 4 acres of Boat and RV storage.  150 slots at $50 x 90% occupancy x 8 years= $648,000. 

I don't mean to run the thread off-course, but if you used an FHA loan to buy a large house as an owner/occupant, then rented rooms as you know how, you could make a killing.

If it's a single family property with just the one tenant occupant (which is what it sounds like), then those are typically valued based on recently sold comparable properties (not the income it's generating). 

My future plans have changed and I’m going to be moving across the country in the next 6 months and the 2 things I was considering doing were: 1) rent the house out for the next 3 years, then sell and the Owner Occupant Sales Exlusion will still apply or 2) just sell the house when I move.

Third, we had no idea what the situation of the occupant was, who they were, or if we could get them out without a fight.

Well this situation is dealing with an owner occupant.
