Waste of time, huge room for error and zero reason for a customer to do this.....any Contractor worth his salt will have better pricing/quality/selection on the big stuff and will have guys on his crew that can do those dreaded 'parts runs' for the little stuff. 

These days as you mention with STR almost everything can be handled remotely...cleaning, painting, locksmith, yard care, even drive by pictures of the house occasionally or internal pictures too. 

Even still, it could be said that I've still lost money due to my time on the tools instead of prospecting as a real estate agent (the cost of lost opportunity).If you can truly do 80%-90% of the work yourself (at acceptable quality levels) and you aren't sacrificing your time where you can get better returns for your efforts, then yes, it can work even up here in Canada.

For example, to get up-to-date property tax data you would need to scrape every county's tax data website (thousands of different websites, data formats, issues, etc...) then aggregate and clean the data.

have looked into Batchleads as well but quality of data looks comparable  Check out traceestate.com $0.08 per individual and $0.15 per LLC.

Which results in more wear and tear and cleaning. 

(Just need to clean filter every month? 

@Christopher HeidrichRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

But we’ve got plenty of testimonials from real people, giving real feedback on the quality of our program and our commitment to our participants’ success.

And note in this I do NOT skimp on material quality.
