So far, we have not had an issue with abuse, but as @Neil Metzger mentioned, that is always a possibility.  

I have a steady income through another business that I enjoy and will not be leaving anytime soon so income replacement is not an issue and I surely don't need another job as a flipper or wholesaler.

The two risk factors I see in this scenario are: The Class A- property allows me to leverage my cash into a better property in a better neighborhood minimizing the risk of higher vacancy rate, the need to rely on subsidized rents, and getting a better qualified tenant mix for the long term, minimizing the possibility of fewer headaches.The Class C/C- property comes with a lot more cash flow due to there being no debt on the property, however it also comes with a lot more risk in the form of all the issues that come with renting a C/C- property and there seems to be a lot of them.

Hi Everyone,The apartment community that I own a building in, has been having an issue with the public coming to dump their trash in our community dumpster.

The only issue is there is 1 boarded up house about 6 doors down.

If there are any huge issues with a gravel basement, I would like to find out now, as we could get out of the contract before we pay the inspection fees. 

But he's on vacation for the week and I'm curious.I have a rental that has been having issues with clogged main sewer line.

There are posts here on BP to address any issue.

The rehab costs have far surpassed our budget due to some masked  issues(missing copper lines in walls, dangerous wiring almost throughout...all covered with sheetrock) Also, the city is requiring us to pour new approaches at "multifamily" thicknesses; about $9k worth. 

Here are some other things that could go wrong which may cause failures:Unknown necessary repairs (i.e. sewer lines, roof, etc)Not having cash reserves to cover vacancies / major repairsUptick of crime / vandalism in neighborhoodVandalism of propertyInfestations (pests, other)Bad tenants / No tenants / tenant family issue impacting stay (i.e. death, divorce)Rezoning of school districts / Loss of accreditation of school district Insufficient Property Management (not addressing tenants concerns, no notification of repairs timely - causing further damage, etc)Not following market pricing on rental / raising rent to frequently or too much at onceLegal issues (i.e. tenants sue for injuries on property, taxation, etc) I think you get the idea.
