If you are located in a stable market with no population loss predicted in the next decade (us census has very detailed and very educated forecasting models for most zip codes)then each month your tenant pays down your mortgage will count as money in your pocket.

Additionally, depending on size of the building/units local code may require fire alarm systems requiring monthly monitoring service and a dedicated phone line.On the flip side (income) is there an on-site laundry, storage locker/rooms for other income sources?  

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.

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??
