Is this presented to the city prior to acquiring a property during the due diligence period or is a land use attorney or city planner used?

BP has an events section that you can trim to local events and as @Barry Pekin said, Meetup is your best resource.

They're going to have a taxable event if you do this unless they 1031 as well. 

As a co-signer, you're typically acting as a non-owner guarantor of the loan, who does not occupy, basically saying you would backstop the loan in the event of default, where if you all are a co-borrower, everyone is on the loan equally with equal ownership.

A escrow might be required at closing to correct a deficiency@Ruben M.I cannot stress enough as to the need to go with a lender who has experience with HUD homes(not just FHA) and has a work around in place in the event the utilities are not able to be activated as well as an escrow provision. 

I didn’t anticipate any of these events either and that’s why I’m saying it is putting us to the test of how good we can be.

Don't see him on the podcasts or webinars or social events. 

Economics depends on studies of past human actions/reactions to formulate models of action to predict future events, which then largely fall on their face as humans screw up the model by doing what they do best - act irrationally.

Although I had lived at the property and was pretty certain that the interior pipes were NOT lead, in the event there were lead pipes found interior to the home, it would probably trigger significant liability and cost issues for most landlords.

However, if you don't follow the rules, you could purchase a property the wrong way, disqualify the IRA, and create a taxable event.
