Thank you for the compilation!

I compiled property lists using Maryland SDAT's website, uploaded them to batchskiptrace.com, and spent lunch breaks @ work cold-calling owners.

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 free methods are driving for dollars, door knocking, wholesalers, craigslist, Realtors, FSBO sites, expired listings, foreclosure sites, put out bandit signs, If you have the funds you can use billboards, newspaper ads, other offline publications., TV commercials, radio ads, do pay per click/adwords, facebook, Linkedin, Youtube, and other forms of online advertising and boosted/promoted social media postings.Bottom line is consistency.

Say you compile a list of people who contact you about buying their house in a distressed situation.

The best way to find off market commercial 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, 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.

In order to more accurately find inputs for our expenses we were hoping to find a way to compile and download average property appreciation, taxes, insurance, water, waste, electric etc..by zip code to an excel csv file. 

@Kevin Mehner Some of the the best ways to find off market commercial and multifamily properties is to compile lists from city and county websites if available or through a paid service like List source, Reonomy and CoStar or you can use free resources like Loopnet, CREXI, Ten-X commercial, Craigslist, tax database, general networking, brokers, property managers, title companies, environmental consultants, building inspection companies, appraisers, landscapers and other companies that service commercial and multifamily properties and driving for dollars.

However, looking at the compilation of all these red flags (and there are a few that I've missed) I am more certain that I should look to work with another company.
