It looks awesome, its bullet proof, dropped tools off a ladder on it and no damage.

Then would start the search for a reputable contractor 

was the water damage visible in the basement when you bought?

But many people like having a feel for what's going on at their property, and find controlling their reputation and product is easier with small or mid-sized buildings.

(I won't name the very reputable course) The course experience is double edged...as I needed to learn; but there was just way too many hours of talk and information that could have been wrapped up in an hour rather than 10 hours.   

I wouldn't depend solely free advice and on contractors' estimates, although there are certainly reputable ones available.

This past winter did some damage and it needs attention sooner rather than later.Does anyone have any recommendations of a contractor to repair retaining wall in Cleveland, OH (Brooklyn Heights).  

Anyone have any recommendations for any of the following:-Local fix/flip mastermind groups or general real estate investing groups-Reputable hard money lenders with a good reputation - ideally one that has reliable contractor references-Fix/flip friendly contractors-Fix/flip friendly agent that has hyper-local market knowledge of North Dallas markets-Wholesalers worth talking to

They don’t have a great reputation in that area.  

The damage could be real.
