I guarantee you stop at 10 sites, one of them is going to hire you to pick up roofing nails, wheelbarrow concrete or sling bricks. 3.

Juts like you don't need a Contr's license to work on your own property and hire subs.Whether or not you should hire an experienced Realtor or General Contractor to work your deals is an entirely different subject.

The contractors I hired out did well up until the last 3 weeks of the project.

Hire a PM if you don't want to be a landlord and enjoy the passive income. 

Hiring a PM company for few properties isn't worth it if you're new to REI.

Now, I have to go to las Vegas to replace every floor molding in the house and I will have to hire an HVAC contractor to repair the AC and hire a welder to repair or rebuild an iron gate and fence.

You can hire a security guard, use fencing/gates with camera's and alarms or just not invest in neighborhoods that bad I guess.

One of the biggest things we see over and over again is people being unsure who to hire, when to hire, how to hire, and how much to pay them.

Which ones did you do yourself vs hiring a contractor?

We will be hiring our first employee (admin/coordinator) by the end of Q3.
