Subscriptions if you're planning to offer streaming services instead of having guests sign in themselves. 

Also, working with a realtor with good social media exposure can be additional free marketing for your property.

We sent one of those “love letters” through our agent and he sold to us for the same price as the other guys offer because he liked us.

However, you do need to handle this situation carefully, make sure you follow a standard screening process to avoid any Fair Housing Act violations.I'm honestly not even sure if you can initiate the conversation with the parole officer, if they reach out to you, or the tenant provides the info and offers the opportunity to call them, that's a different story.Make sure you apply the same screening criteria you use for all potential tenants. 

Instead of telling me I'm in over my head, why don't you offer some solutions for me rather than offering solid advice of it only takes 10 minutes?

My wife and I have made several offers on multifamily houses recently but keep being beaten out by (lower) cash offers.

I’m being asked to provide 12 months of cancelled checks in addition to a lease to prove that I’m renting.

I am going for a house hack with Fannie & Freddie conventional , After my 4th offer was rejected going over listing I asked the listing agent for some additional info and they stated that for this property there were 42 showings within 4 days. 1 cash offer, 1 commercial, 15 conventional and one FHA with 9 waived inspections, 11 escalation clauses and 5 appraisal gaps.

You could consider a sellers home inspection (paid for by you) prior to listing the property so that buyers make their offers based on known areas of attention.

In addition, because their rent is high tenants don't stay as long further increasing the vacancy time by increasing the frequency of turnovers.
