@Tarik Kafel recommend checking NARM.com for professional and licensed PMCs.Also, here's our copy & paste advice: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.

Was it just through word of mouth/networking? 

Your PMC is recommending the path of least resistance, because mold claims could be VERY expensive.Also, many insurance companies will NOT cover mold issues.So, call your insurance agent and see if this will be covered or not.At the same time, direct your PMC to get a professional mold test done to determine if there actually is a problem or the tenant is mistaken or exaggerating. 

NETWORK!!!

The network name at each place is the street address. 

Did you have a professional inspection done and have you really gone over it to project what other repairs may be needed in the future?

Also find out if they have a move out list for you to check and what the expectations are (ie I expect any carpet to be professionally cleaned and want a receipt, over is cleaned, if you had a pet any poop in the yard to be picked up, etc).  

You should contact your attorney and/or tax professional to obtain advice with respect to any particular issue or problem.

One is having the tax status of qualified real estate professional, which basically means that your primary job is on real estate.

Readers are advised to seek professional advice.
