I am looking for recommendations on which CITIES should I attempt to purchase the property.

I've found houses listed for rent on Zillow for over 100 days vacant and will attempt to purchase them from the landlord. 

Are there ways to judge a person's character/background to determine they won't spread information? 

I don't care if it's regular wear and tear or damage caused by the tenant, I want to know and I don't want the tenant to attempt to fix anything. 

I tried uploading my picture but I am still unsuccessful after many attempts. 

Cut off all communication from the tenant, including promises to pay or attempts at negotiation, and let the lawyer clean up the mess.While your attorney is handling that, you should be looking for a property manager.You can start by going to www.narpm.org to search their directory of managers.

It's called the 5 C's of credit character, capacity, conditions, collateral, capital

It's grandfathered in because it hasn't been redeveloped but this is where municipalities attempt to force redevelopment.

That being said, you should consult an attorney to help draft the terms you are attempting to construct.

I figured if I just purchased the property and put a mobile home on it, I could rent it out until the property was paid for and once I’ve got all of the note paid off on the home I would either continue to rent it until the market picked back up or just attempt to sell it and get out what I’ve out into it.
