@Chungying ChuIf you want more liability coverage, ask your insurance company if you can increase it.

My company provides an all-in-one solution for clients.

One if you do not register your company as a foreign company you usually cannot file an answer in court if you are sued. 

@Kyle Carter My top recommendation is to begin by contacting property management companies in each target area.

In order to have checkbook control, the IRA account will need to be at a trust company that will allow the IRA to invest in an LLC (where you will be the manager and your IRA will be member - an as manager you will have checkbook access to the LLC bank account).

How do I research the company?  

They seem to be a reputable company, but nothing beats personal testimonies!

Or suggestions for other companies that provide a similar service?

You can reach out to the Title company and see if there are any funds remaining for dispersement, if so then ask if there is a way to make a claim to those funds.

I own a roofing company in Denver and a separate gutter company there too.
