@Greg Scott I have a picture of me inside a hole looking an a rusted, broken, and clogged cast iron pipe.

How do I get the phone numbers of the owners of the properties?

I think that it is a good long term investment with some serious upside, but don't kid yourself - your car (or your tenant's car) will likely get broken into at some point.

See, Nada, only new phone."

Quote from @Mike Levene: contractors should give exact quotes, come in give you a full detailed list of how much it will be to cost for labor and materials broken down.

What we found was only one other person contracted under $200 per square foot for clients and they also built within the city of columbus. the numbers have a much higher premium the closer you get to downtown. if you can't get the numbers to work my recommendation would be to get closer to downtown. we do build to rent development and single family home development and every line item is broken out. on the triples we have to build exterior staircases etc there are some things you can't really understand unless you build a lot. hope that helps but no one is going to build you for 110 a square foot. the lowest cost homes in our market at cost without a profit barely dip into 140 a square and we are in one of the cheapest construction markets and states in the country. 

The repair was extensive and costly, requiring excavation (about 3x6 feet) to replace the broken section and clean up the mess.

The broken kitchen sink needs to be replaced.

If you have broken up those stays, every 2 weeks, then you should be able to call the police and have them removed.

Not sure if they called off the sign, or if they still have the listing up on their phone and find the number to call from there.
