Tell them to pound sand and if they complain, let them take it to the housing department or a court and see if their case has merit.

@Eddie Starr  Completely agree with Greg's comment above, a local bank and their commercial lending department would be your best bet. 

@Brenda WhittakerSounds like you should do the following1) Notify the tenant of an increase in cost, if they don't agree, ask them to leave or evict them if necessary.2) Do a full inspection of the house and prepare to do some maintenance and keep up with it, I actually have a resource in this department that helps coordinate maintenance on your behalf so let me know if you want my recommendation3) Reach out to a qualified leasing agent or a property manager who does 1 time leasing, OR screen tenants by using services like Naborly that do tenant screening for you.

I would set up a meeting with someone in the community development department and ask about the parcel.

If not I will just do copper and insulation  Call  the building department as to the definition of non potable.

Ultimately I will probably have to get what break I can from the Water Department and suck it up this time. 

And the fire department had to inspect the foundation, confirm that all burnt wood was removed and that something did not happed to make the cement more likely to crumble and that the metal bracing did not melt or soften.This was in CA is an area that had over 300 houses burn during a wildfire a few years earlier, so maybe they had way more experience nd thus requirements than most places. 

For the tear down, sometimes the local fire department will burn it as part of their training is it is not too close to the neighbors.

for clarity send your business plan with copies of your marketing to your state department of real estate and ask for a formal ruling.. they will do that in writing.. once U have that your good to go on whatever they tell you.I know that advertising in public be it e mail blasts website etc homes you dont own is simply not legal in any state.it just up to the states if they are going to spend time and money regulating those activities.. and in Inner city urban core where this activity is about 80% of the transactions..
