Or does it have to based off a straight paying tenant?

Tenants should pay for that.My lease considered normal to be a few items hung using 1" nails or smaller.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

Having to go see a piece and pay for transport makes used less attractive. 

I'm thinking if I ask the tenant to pay the other half, I'll probably need to make an amendment to the lease to reflect that.

Everything from pay per click, to networking (I've found BNI groups to be a great resource), to cold calling.

All you're doing is paying for that NCF upfront. 

@Michelle Hardy Just adding, check your local city too for their requirements, many have specific requirements that the state may not have.Here in VT in the towns my properties are in, there is not a requirement to keep them separate or pay interest. 

Quote from @Jarret Jarvis: Hey Will, congrats on paying off your property and your successful stock market investments!

It may sound nice to pay a 6% management fee but the extra fees can add up to be more than the other company that charges 10% with no additional fees.
