Like websites or anything that gives accurate information. 

Is this accurate?

That is accurate for ARV conservatively.

@Dwight HenningRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

Connecting with local contractors or experienced investors in your area is also very helpful for getting accurate numbers.For ARV you’ll want to look at comps; You can start on Zillow or Realtor.com but I highly suggest connecting with a local agent.

There's a big swing here in insurance and tax calculations I see and getting those numbers accurate are critical for your ability to not miss on good deals

They gambled, and lost.

To navigate the nuance in the laws properly for compliance and to accurately structure our LLC, I am looking to consult with an attorney who knows immigration + business + tax laws. 

Additionally, be sure to have an accurate ledger and your signed lease agreement.
