Most of my houses earn around 30-40% total return year after year.  

Total number of people in the 4 plex is 6. 

I'm totally fine using resources like books, online research, and AI, but I was looking for real-life, experienced individuals who could shed some real light.

Typical Project Management Fee for a GC General contractors (GCs) typically charge a project management (PM) fee of 10-20% of the total project cost.

The total cost including construction and permits (but excluding the land) comes to about $2.14 million.

So, $3,000 per call multiplied by the total number of calls you have the company place.Furthermore, while most real estate investors don't realize that their calls can be considered "telemarketing" under the TCPA because they think of a telemarketer in a common sense approach versus the legal definition, there would probably be other violations under 47 C.F.R. 64.1200(d) which could add another violation to the mix.

I found nothing good at the ones near my STR, it was total crap that I would be embarrassed to have my guests use.

Keep looking. totally agree with you, thanks for taking the time to responde

The sum total of taxes of each of the 4 units will usually be higher than if it were apartments.

I'd be very surprised if they would consider a less than total deal, unless they're really desperate.
