I see multi family listing over there alot

Looking to buy and hold a multi family building in the chicago area or subur.

We've been laying the groundwork for a move to a larger property via running these 22 (soon to be 23) units successfully on our own, and by participating in syndications as passive investors where we learn at the feet of investors much more experienced in large multi-family projects.  

Multi-Family with NO Certificate of OccupancyI have discovered I am in a deal to purchase a houseand units with seemingly NO Certificate of Occupancy from the City.It appears these are supposed to be applied for by the original contractor,however the city has NO record.These units have been renting since 1951,does anyone have experience in this area ?

I am looking to purchase a multi family in Dallas.

I am an out of state investor of multi family living in CA.

It's going to be older/neglected real estate, so the sellers will generally go along with it if it helps get the house sold.Example:Identified a below-grade un-permitted basement bathroom with a jenky pump lifting the toilet waist up to ground level and into the sewer system that was all sorts of a hot mess, no way anything about that bathroom is up to code. 

Multi-Family Millions by Dave Lindahl is pretty good in that regard.

Just out of curiosity, why are you all targeting a house with a lot of rooms instead of a multi-unit house.

We are now at the point we'd like to move into small multi-family.
