I was reading Build a Rental Property Empire via kindle and took a moment to browse the internet; attempting to gauge the quality of my rental property I acquired about 5 years ago.My name is Wilson and am from the Milwaukee area.

Lucas Hall, guest on episode 6 of Real Estate Rookie, also mentioned these quality criteria’s. 

I am thankful, my partner and I have good quality tenants.

Frankly I'm surprised that you can't find  good quality agent who is willing to pay for warm leads - maybe go to Zillow and contact some of their "FEATURED AGENTS" since they are already paying Zillow for just that.

. $60k for a 15 unit mobile home park equates to $4k/unit, which is outstanding!

I pay my crews damn well, and I expect matching quality and production, and I get it, we have a win-win relationship.

You might have bought a higher cap rate but tenants and quality of location might not have been an A.For location you can have A,B,C,D and tenant quality (mom and pop tenant single operator, mom and pop tenant multi-unit operator, franchisee single tenant operator, multi-franchisee location operator, national tenant (private credit), national tenant (publicly credit rated but not investment grade), national tenant (investment grade).Then you get into how many locations or type of credit is backing the lease and a ton of other factors. 

This type of quality work is likely the reason they are suggested a ton on BP.

That's very dependent on the market, size of the property, class of neighborhood (low or high quality finishes) and end use of said property (rental or flip).

Those commercial tenants that have expressed concerns over rent & cam payments, I've been using an addendum "security deposit towards outstanding balances", where that security deposit will need to be replenished at least 6 months before their lease expiration.
