Are there specific websites I can refer to?

IE FSBO, off-market deals..The deal I'm referring to was an expired listing, though if it was on-market I can still make an offer and state in writing that the selling agent isn't the dual agent and will not be representing me; this will typically save the seller 3%.  

First reference look at average apartment maintenance/cap ex which NAR publishes.

I explain I will proceed with the eviction, the eviction will show with any decent credit/background check and will negatively impact their credit score, that I will attempt to garnish future wages, and that it will be very difficult for them to ever rent a nice place in a low vacancy area like San Diego.As part of my tenant criteria: no evictions ever (no excuses accepted), decent credit (I want tenant to have credit such as they do not want it to take a significant hit, strong LL references and in the add I specifically specify paying rent alone does not suffice for a strong LL recommendation.I recognize with my number of units and how many years I have been a landlord, I have been fortunate to never having to evict a tenant and at some point my good fortune in this matter will end.  

If anybody has any clue as to what he might've been referring to, please share!

In reference to finding the best contractors, I highly recommend networking and getting to know high volume investors in your area and asksing them for recommendations.

Negative, if you could refer me to one it could be greatly appreciated 

Recommend 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.

For reference, in the pictures, we converted a loft space into a thriving community space for the arts in Brooklyn.

If we need to find our own PM, we will strictly base on referral and reference.
