But once you have a tenant, it's easy, if you fixed your house to code or have done somewhat a decent job.

I own a restaurant that is going through a tear down and rebuild and am up to my eyeballs in contractor issues, etc (more city code issues than with the contractors.

Give your name and number and ask them to respond if they are interested in selling or maintaining the house to local and county codes  since it is clear that the house needs some maintenance. .I use the code approach to push the issue that their asset is declining and see if you can help - maybe they got cited already by the city - I find it generates more response than just a I BUY HOUSES card. good luck!

Lower income jobs, purchasing properties below replacement cost, some poverty, city government that has a understaffed code enforcement department, local lenders that understand real estate and the market, low quality properties for rent so you can provide a better product...  

(see Ohio Revised Code section 4735.022) However, it is completely legal to assign a contract on a property, and to collect a fee for said assignment.

Commercial real estate contracts are lengthy and one word and where it is placed etc. can alter everything.

I love my architect in SF because he knows the nuts and bolts of pulling permits as much as he knows building codes and design.  

Also, who must I meet with in order to ensure that what I want to build is up to code/ legal?  

What neighborhood grade would you give zip code 45417 within the bordering streets of Nicholas Rd, S Broadway, W 3rd and S Gettysburg??

It does a lot of things "OK" but to do really "great" things with you better understand how to open the hood and work with CSS, do coding, etc.
