It creates inventory on the market that wasn't there before and increases surrounding home values in the process. 

As a new real estate investor, I recently bought a SFH and hired a PM company to handle it.

I house hack my primary home in which I do a thoroughly credit check, background check and interviewing process.

I am now trying todo a cash out refinance to pay off my HELOC so I can repeat the process.

I have all my systems and processes down to fix and flip a house tomorrow with the team I’ve built, i have private money lenders that want to invest but wanna see some skin in the game first.

However in the past I've done the majority of the physical labor on the jobs, and have grown weary of this part of the process, I've tried hiring contractors but pricing seems so high it's hard to make deals work, so my question is where do you find people to hire full time for general work like drywall, flooring, painting, etc.....

About 10% of home sales the seller does not hire an agent.

What are their screening criteria and processes?

I can offer insights from the perspective of someone who hires real estate analysts

Now hire the best PM you can find.
