I learned how much an escrow account check matters to your overall mortgage payment.

@Stacey OlsonRecommend 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.

I also understand accounting and legality may play a role.

Here in the USA you need what's called a "construction loan" and it's also very hard to find a company that will insure you if you're a newbie.

Or does one need a special license / need to open a company?   

Always ask your agent to ask the listing agent which title company/closing attorney that they are working with.

Multiple new accounts with almost 0 posts are saying they are good....RUN 

You also need to account for the eviction process, state laws etc...
