If you are searching for offmarket, you can network with local wholesalers, and also use something like dealmachine to generate leads.

Quote from @Scott Trench: Wait... the guy who buys all the ads (through Google) on BiggerPockets YouTube videos and attempts to reach BP viewers says that Tax Liens are the best way to build wealth, asking me repeatedly and agressively why I'm not doing it? 

I was doing some general forum searches and saw this. 

Here are a few suggestions on how you can maximize the wealth of information available: Check out the blogs and podcasts, or take advantage of the search feature (magnifying glass).

When all the dust settles, and the  person searching is tired and discouraged and gives up, Jerry may not have bought  a single lot, but he's made some money from the training he sold you, which was his main goal from the beginning!

Just Google Maps and see it from yourself.

I think you can through BP or through the aforementioned REI meet ups more than likely.i am inclined to agree with a previous poster in that i'm not sure driving for dollars will necessarily yield you what you are looking for.Network with as many other MF investors as possible in your area and find an agent that knows the market and can at the very least set you up on an MLS search for your criteria.Coupled with BP's deal analysis calculator you can then begin underwriting properties you receive from the MLS with your agent or on your own to better understand your market and tailor your expectations moving forward.I'm an investor focused agent that focuses on MF and while we are not in the same market if you have any questions about moving forward with MF LTRs i'd love to see how i could help.

I'd say just start your search with all 2-4 unit properties, and when you find one where the numbers make sense and it checks your other boxes (somewhere you actually want to live and house hack), then it probably makes sense. 

I saw this post in my own search for rezoning information in Denver.

Called up to them and they asked me to search for their lawyer name.
