A DCR of 1.05 means you are just barely paying the mortgage, is there some serious upside on rents you have not mentioned?

figure $12K for a bare bones 20x22 garage in Chicago which will end up messing up your parking spots for the other tenants.  

They can charge 10% for any repairs and then charge another 1/2 month's rent to re-lease the place.There are people who really don't want to be property managers and so therefore do the bare minimum at their job.There are property managers who take money from the tenants and don't remit to the owners.

Bare with me, but the reason I kept all duplexes as experiencing the same exact problems, is to keep things equal across the board to see what would happen in this scenario.  

After a 20% down payment the monthly mortgage comes to ~$235 leaving just over $300 cash flow, so barely $100 per unit. 

Just spot checking the search results there are addresses I know are barely standing, partially burned, or boarded up, that they have categorized as "occupied". 

I would add that land is highly regional.. some of the things you mention should be self evident in a physical inspection.. and depending on where the land is it may or may not have any true underlying value.IE.. take a bare lot in an area were homes sell for far less than it cost to rebuild them.. in those areas lots are basically worth zero.. 

Quite often they report many "dumps" and thus was wondering if in the landlording business (especially small timers like myself or perhaps even larger mgmt groups) many focus on the bare minimum for a rental offering?  

A CFD is a pink elephant today.

Barely any rentals.
