Zillow, Rentometer, and local property management companies can give you rental comps.

Any recommendations on companies that provide these services?

My plan for property is to rent after rehab which the same realtor has a property management company we’ve discussed using. 

Is it difficult if I purchase a property in my name and then I want to transfer the mortgage over to the LLC will my mortgage company allow that?

Over the years I became more and more involved with some of those people and as an adult started taking them to lunch to "pick their brain" (Not my favorite term but you get the point).One of these Gentlemen I have continued to meet with and give him updates on my business.

Real estate is all about continuous learning.

Also it depends if you hire a company or if you are hiring a person and paying them hourly - the hourly cleaner will be cheaper, but there's more management involved on your side.I pay $120 per turn for a 2br condo.

My lender is a home loan company and not tied to any bank.

I'm with a construction and design company and we operate in NC - feel free to reach out, would love to work with you and help you create a high-performing STR.Here are a few we did in NC for you to check out:-https://www.airbnb.com/rooms/755582185230853225?
