In my lease, they become holdover tenants and are charged 4x the monthly rent, prorated on a daily basis.

Deep dives with Financial Independence (the Mad Fientist), Journey to Launch (Souffrant), Money for the Rest of Us (Stein), Optimal Daily Finance, Stacking Benjamins, Big Picture Retirement, and Radical Personal Finance (Sheets) all have great information. 

Hopefully one day I'll say it was the best decision I ever made for my career, personal daily life etc.

They are often Agents who like to try and work with investors but unless you have investments and work with them daily its difficult to understand how it all works. 

Stocks go up and down daily but real estate, read the trends.

@Taylor DaschI understand the rule, but I read and hear on the daily that people will finish a property, then pull the money out of that property to pay off the previous loans,, then do a heloc on the property they just finished, just to buy another one and repeat.

Also, the agent is solely transaction based, so once they get their commission check they have zero accountability to you.Contrast that with a property management company (PMC): they have to deal with your property on a daily basis, until you sell it or fire them. 

If you look at how banks do it, they typically charge a one-time fee of around 4-5%, not a daily charge.The other issue is that you shouldn't charge a daily fee and let it go forever.

I've drove around a couple different area's and jotted down addresses and owners phone numbers for my realtor to call, check Zillow daily, and check Facebook group chats for off market deals.

They will have to manage whatever you buy on a daily basis until you sell the property or terminate them.
