One of best ways in the short term would be to connect with a Registered Real estate agent who shares your goals and  would be willing to search the MLS on your behalf.

I know this topic has a lot of forum questions dedicated to it already, but my go-to resources direct mail list resources seem to be set-up differently then in the past.I have used Reonomy and List Source previously for direct mail leads with good enough results that I'd use them again, however Reonomy has just recently been forcing an annual contract instead of monthly which is WAY too costly for what I need, and List Source has split up the commercial properties list differently then the last time I used them and almost all of them are listed in "Commercial: miscellaneous" with every other property types, and I have tried filtering differently with no positive results.My goal is to get "true ownership information"(Names, Addresses, Phone Numbers of people who own LLCs & INCs), but for now this is a one time thing, so I don't need an annual contract, and I don't want to pay thousands for Co-Star for an entire year or something.I do have TLO, however pulling multiple owner's information is very time consuming, so I'd like to do this only for a few select properties.Long story short, I'd settle for any ownership information whether it's company data or not, but I'd like to do a one time deal and get 500-1000 leads.

Make sure you find somebody with like minded financial goals and ambitions.

My goal is to go all in and retire from my police career.

What are your goals?

Also, cash talks so look into a hard money or private short term investor so you can secure the deal and then structure it later the way you see fit!

I am not sure if that is normal, these guys are in the SF Bay Area, but they put in the labor to do their renovations on those periods of days that they are off and they seem to love the time fit between the two.

But I am open to other opportunities.Long term goals: Invest in Real Estate, of course! 

What ever you get, make sure it can fit full sheets of plywood and drywall inside. 

I decided not to go the STR route with my properties as they were not a good fit.
