The city wants to tear the property and surrounding properties down Zillow said it’s worth 38000The city offer me 13000.I could use some adviceHard to give advice with limited information, but as a general rule, the longer you wait and the further down the line their project is the more valuable your property will be to them.Zillow (and all automatic online) estimates are very unreliable, so don't base on that.

The objective is to upsell to a master mind program or the artificial intelligence datasets, which also have zero response rate.

I would approach this question with a few things in mind, such as what are your investing objectives and how much time do you want to dedicate to this. 

Spend at least 2 hours per day researching online about your desired investment strategies.

But damned if I can find anything online about landlords using it!

That's the main objective.

Documenting your journey online or engaging on LinkedIn can also help expand your network.

My recommendation would be to get approved as a Landlord, contact the director's office and request that an inspection be completed before a tenant is selected (sometimes they will do this as long as you select a tenant within 14 days - which you want anyways), and have an online application and screening resource in place.  

Online metrics can be good, but they wont paint the whole picture. 

Then you'll need to find land, acquire it, find a spec home buyer and set up meetings to design plans or buy a set online with mods.
