North Bay to be more specific. 

Once you have that information it is also important to look into the stats and data of the specific market you are looking to invest it. 

I believe I have an unfair advantage when it comes to finding the best person for a specific job, due to being on union job sites all around the east bay daily.

I am interested in acquiring a property with pretty specific criteria:Multifamily (duplex to quad) with at least 1 unit a 3 bedroom/1+ bathroom.

It depends on the specifics, and especially how well it's managed.

If you ask someone specific a question in a forum be sure to tag them so they get the e-mail alert.

You need to be a little more specific, what type of advice are you looking for? 

I'm not going to name specific markets but there are a LOT of cities throughout the US within geographic boundaries that are often very close to each other, that have extreme disparities in income, educational attainment, safety, etc. 

The HOA restrictions specifically say that "Pets must be kept in a manner that does not disturb the peaceful enjoyment of residents of other lots" and one of the terms of the lease is that the tenant abides by the HOA restrictions.How would you handle this if it continues after you warn the tenant, and the neighbor keeps complaining?

Unless you have a specific strategy, there's no reason to put down 25% on a 2-4 unit property.
