We ultimately sold that one to a handyman and only made about 1/2 the profit we could have made on it - but we were worried about being able to sell it on the open market with how bad it smelled.  

The path to wealth is a road through a grave-yard littered with bodies all saying "it was so good, until....". 

No body ?

I would be afraid of ending up like Benito Mussolini after WW2.If you don't know, he and his mistress and his generals were summary executed and their bodies were hung upside down in Milan at the carport of a gas station. 

Look up medical for Shock Wave therapy and/or Pre Nuvo body scan.I just don't like Enabler or Victim approaches. 

Over the years I picked business degrees, real estate license, tax preparation training, loan officer licensing and training, investment / CFP training and it is all tied together in one big connected body of knowledge that emphasizes appreciation, debt pay down, cash flow, and tax write-offs...  

Loud parties after hours, smoke smells between units, roaches coming from the neighbors, and aggressive dogs. 

Something where I can make selections such as limit to topics only or include the bodies.  

Any way  so in a short hand way I agree with you on stopping to smell the roses when your young enough to do it.. but many simply dont have those choices they choose a job that they must keep at until they can retire and maybe  a week vacation to Hawaii or go party at Vegas is some highlights. 

And third, you can make sure your lease's guest policy and non-smoking clauses are beefed up and made extremely clear to the tenants.Lastly, you probably inspected the property at least once or twice before closing, so you would have likely been able to determine if there was any significant smoke damage or cigarette smell inside.
