Just some advice, we encountered some struggles to get financing due to our condo being considered "non-warrantable".

I've definitely encountered my share of melted vinyl siding. 

The plumber went to the property and encountered an issue where he too couldn’t access the stack line and found no outside clean out and said to gain access to vent he would likely have to make cutouts in the wall between the bathroom and the adjacent bedroom.

I had to make the decision to either sell all of them and focus on another type of asset with less issues, or buy so many that the scale absorbed the inevitable issues one generally encounters with older properties in rough neighbourhoods with sometimes problem tenants.I chose the scale route, and we are well on our way to 300 units.

A golf course would have the potential to be the biggest money pit you may ever encounter.

Does anyone have input on any issues that I may encounter?
