@Heidi Saelee there's no logical reason for you not to get your monthly statements timely.Whether those statements show you're owed money or not is a separate issue.So, unfortunately, it's probably time to find another PMC.Be careful about WHEN you report your current PMC to their RE Board, state AG, etc., as they may not cooperate with the transfer of your property to the new PMC:(

@Lloyd PreeceRecommend 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.

Hello Bigger Pockets Community, my name is Mark (24 y/o) , I currently live out here in California, right in the middle of LA county and Orange County.

Check with any current/recent customers also.  

Unfortunately, this property has a variable interest rate that is currently 6.5 %.

Life choices.Now look for your REI strategy that will achieve your targets in your market, with your current resources.  

I have (13 months) remaining on a lease of a townhouse I am currently renting.

Are there any current active investors in that area who can share their experience of that area and what kind of rents they are fetching?
