So this year I hired a very expensive CPA.

As many agents are not familiar with 1031 exchanges, I think that hiring a 3rd party expert is definitely the right move. 

As of now I don't think I'm going to hire a property manager since it's just one property so I've been looking into software to streamline the whole process of managing a property.

I decided that I was going to do as much work myself as I could, and that I would also hire my wife's coworker, who had experience remodeling homes, to help facilitate the work that I wouldn't be able to do on my own.

should I just hire attorney and let them know if they don't pay accordingly to the contract, a legal action will be taken against them?

The buyer should hire an inspector (with your direction) that they trust.

Even if the project were to be executed in two phases, the land value would still fall short of all of the equity needed to do the deal.So, Your Options appear to be: Sell or Lease the Land, Develop it Yourself (with or without an Investor), JV with an experienced developer or hire and pay a developer a fee:1.Sale or Lease of the Land demands that its value to be established2.Develop yourself looks like a very heavy lift if you haven’t done this before.

I am looking to hire a general contractor to reinstall my roof but having a hard time finding one.

My wife wants to be one, but we don't know which website / area would be the best to go to for getting certified.2) when you bought your first rental(s), did you hire a management company immediately to tend to them, or did you manage them yourself?

After the inherited tenants moved out we hired a contractor to paint, fix small items, and lay new floor.
