What most people I´ve spoken to do here is just going to networking events, talking to a lot of people and slowly compiling their investor lists, but this is probably not a very efficient way.

My wife and I live in Northern California and thus far have compiled four doors by buying, moving and then renting.

I just spent a great deal of reviewing the statute and reading legal docs and articles on the subject and compiled a notice that satisfies the aforementioned provision. 

You can also buy lists from companies like list source and there are some REI software companies that have a cash buyer search feature.Best way to find motivated sellers is to purchase lists and compile lists from city and county for 60-90-120 days late on mortgage, pre-foreclosure, delinquent taxes, water cutoff, code violation, probate, divorce, high equity, etc. and mail or cold call.Other methods are driving for dollars, door knocking, wholesalers, craigslist, Realtors, FSBO sites, expired listings, foreclosure sites, put out bandit signs, billboards, newspapers, other offline publications.You can use pay per click/adwords, facebook, Linkedin, Youtube, and other forms of online and social media marketing.

I would recommend you start there especially if you know it well.Yes these properties can be found on and off market.The best way to find off market and multifamily properties is to compile lists through a paid service like list source, Reonomy and CoStar or you can use free resources like Loopnet, CREXI, CBRE, Craigslist, tax database, brokers, property managers, title companies, multi family inspectors, appraisers, landscapers and other companies that service commercial and multifamily properties and driving for dollars.The real key is in how you approach the owners and then the follow up.

If so, what they're renting for can give you a fair bit of info too.Your best bet is to compile this info and come up with a "per door" average price to get your total ballpark number.

The title company compiles the title report by searching the history of the property from county records.
