One that I'm getting close (hopefully) to the end of, was a flip that was a public nuisance property with two lots on either side full of junk (like 10 dumpsters worth..)There was great opportunity with the house, but we bought the other lots as well and cleaned them up (as no one would ever buy the house with those lots filled with junk). 

I would consider getting out of property management and getting into cleaning IF you think they are doing better than you . 

A little conversation redirect here: this "method" as posed by the original poster has been thoroughly and utterly debunked.A quick analogy:I brush my teeth two minutes per cleaning.

Then I sit down with a spreadsheet and analyze all parcels for an area and generate a list of target properties right from my computer.  

I generated the list by combining Zillow's smooth, seasonally adjusted home value dataset (ZHVI) with their rent index (ZORI) for metro areas.

Quote from @Matt Weddon: Really what generated this question was a section from Brandon and Heather Turner's Management Book, which has been incredibly informative and helpful.

Additionally, consider operational costs like cleaning, staffing, and marketing, as they can quickly add up.For management, outsourcing to a professional property manager or leveraging tech platforms for bookings and operations could streamline things, especially if you plan to scale.

That said there are some nuances and requirements to property implement interest tracing so ensure you talk to your tax professional ahead of time and keep the funds movement as clean as possible. 

The pay stubs can be hard copies or digital PDFs generated directly by your employer and sent via email; we cannot accept screen captures to verify income.Once your completed application materials have been received and it appears that you would meet our qualifying criteria, we would send you a link to perform a credit/criminal background check (this minor expense would be yours), and if those results come back acceptable, we would offer to proceed.

The IRS should have cleaned up on the billions of tax fraud being committed.
