Knowledge and use of this information should help you to make a more realistic cost estimates for your models. 

@Jay Hinrichs yes to my knowledge there are other states that changed regs.Off the top of my head.

When you are new, you can be your worst enemy (due to lack of knowledge, ego, and FOMO).If you are new, do you have a person who tells you that some deals suck?

My personal experience after 40 + years in the real estate industry is that “wholesaling” is a very INEFFICIENT AND INEFFECTIVE way to gain knowledge and experience relative to real estate.

.- Tenant submitted a work order for low water pressure in 2 bathrooms- Tenant submitted a work order because the garage door doesn't close all the way and left a 2-3 inch gap at the bottom- Owner initially refused to address either work order- Owner demanding the tenants place furniture pads on each piece of furniture- Owner calling multiple times to speak through the work orders, asking when they've been scheduled, calling a couple days later requesting the invoices- Owner calling because they want to access their storage in the basement so they can remove several pieces of furniture being stored- Owner now emailing requesting multiple property inspections throughout the lease cycle- Owner questioning my experience and relative PM knowledge because I'm not following up with her in a timely manner (the following day after the work order)Keep in mind, this is 2 weeks after the tenants had moved in and the tenants are very happy in the home.This is something we see on a regular basis.

How limited is your knowledge base?

The tenants have paid and if someone is thinking about moving out then an extra surcharge that hits if they aren't out in time for us to turn the place for a lucrative AirBNB short term rental can help massage the move out timing.That said with MTR we do not have the cleaning costs that eat up a lot of STR gross, and its lower hassle in some ways.  

Unless you have time, desire and knowledge, hiring a property manager sounds like the right option.

It will all depend on what your goals are.Ask them questions that will help you determine whether they have the value/knowledge that you'll need to get closer to your goals.

If so, I'd 1) join a real estate investing mastermind that focuses on your asset class of choice (multifamily, industrial, storage, etc.) and learn as much as I could - it's worth the $10k-$20k in both knowledge and connections.
