From what you have given us, we don't have enough information to pass judgment.

This will help you make a more informed decision. 

Because you want property information that realtors are listing correct?

I have been getting a lot of questions from owners about letters being sent out by the municipalities here in Milwaukee to tenants informing them about potential lead service lines leading from the street into the house.

Firstly, well done for persevering and trying every avenue you thought would get you the data you needed.Most would have caved earlier and handed out there hard earned cash for old, saturated leads/records from the same prominent platforms which dump them pretty much when they receive them from either 1).the same large brokers AFTER the county has listed them on the county website or, 2). from the counties themselves directly AFTER the county has listed them on there own website, or, 3). from data scrapers on Upwork/Fiverr who scrape the data from those same platforms AFTER the counties/brokers sell those platforms the data being scraped by the freelancers.Anyway, rant aside you seem to of made the same mistake i made when I first started branching out away from providing leads to my original couple of clients i got from Upwork who wanted me to scrape data from court records in FL for pre FC leads.Simply, I didn't know where to look for the information I needed in states outside of FL.FL only allows the judicial route to foreclosure so I only needed to know/find/scrape the data from Lis Pendens documents for counties they requested.

The information contained in this post is not to be relied upon.

Perhaps there is a realtor association that has this information?

The sellers have not been responsive when asked to provide that information, which is why I was wondering if it's a typical practice prior to submitting an offer. 

I feel if there is too much information out there like that when new investors start analyzing deals and they don't see the numbers work like many describe it discourages them to the point of passing on good deals or passing on real estate investing all together.I am still new and didn't get started until 2021.
